at a pressure of natural gas up to 1.2 MPa inclusive - lining the cleaned inner surface of gas pipelines with a synthetic fabric hose on a special two-component adhesive, subject to confirmation in the prescribed manner of their suitability for these purposes for the specified pressure or in accordance with the standards (technical specifications), the scope of which applies to this pressure.

When pulling, polyethylene pipes are used without a protective sheath, with a protective sheath, with co-extrusion layers PE 100/PE 100-RC. When pulling a polyethylene gas pipeline inside metal pipes, measures should be taken to prevent its mechanical damage.

It is also allowed to use other reconstruction (restoration) technologies provided for by GOST R 56290.

(Changed edition. Rev. No. 2)

5.7.2 Reconstruction (restoration) and overhaul of worn out steel gas pipelines may be carried out while maintaining:

Intersections of restored areas with underground utilities without installing additional cases;

Depths of laying of the restored gas pipelines;

Distances from the restored gas pipeline to buildings, structures and networks of engineering and technical support according to its actual location, if the pressure in the restored gas pipeline does not change or when the pressure in the restored gas pipeline rises to 0.3 MPa.

Restoration of worn-out steel gas pipelines with the possibility of increasing pressure to high pressure is allowed if the distances to buildings, structures and utility networks meet the requirements for a high-pressure gas pipeline.

(Changed edition. Rev. No. 2)

5.7.3 * The ratio of the dimensions of polyethylene and steel pipes during restoration and overhaul by the pulling method is selected based on the possibility of free passage of polyethylene pipes and parts inside steel pipes and ensuring the integrity of polyethylene pipes. It is recommended to seal the ends of reconstructed (restored) and overhauled sections between new polyethylene and worn steel pipes.

SOLUTION

IN THE NAME OF THE RUSSIAN FEDERATION

Oktyabrsky District Court of the city of Kirov

Judge Starodumova S.A.,

under the secretary Kultysheva E.S.,

examined in open court a civil case under the claim Prokashevoj T.A. to Gazprom Gas Distribution Kirov JSC on the obligation to replace an expired gas pipeline,

INST A N O V&L:

Prokasheva G.A. applied to the court with a statement of claim against OAO Gazprom gazoraspredeleniye Kirov, represented by a branch in the city of Kirov, on the obligation to replace an expired gas pipeline. In support of the claims, she indicated that the plaintiff lives in the house at: , built in 1972. In the same year, a gas pipeline was put into operation to this house, i.e. the gas pipeline was completed 43 years ago. According to clause 5.3.7 of the Safety Rules for facilities using liquefied hydrocarbon gases, approved. By Decree of the Federal Mining and Industrial Supervision of Russia dated May 27, 2003 No. 40, existing external gas pipelines must be subject to periodic bypasses, instrumental technical inspection, technical condition diagnostics, as well as current and major repairs. Underground gas pipelines with a service life are subject to diagnosis: steel - 40 years; polyethylene - 50 years. Gas equipment (technical devices) are subject to diagnostics after the service life specified by the manufacturer, but not more than 20 years of operation. In case of violation of the operation of the gas pipeline due to leakage, if there is damage on the gas pipeline, an explosion of the house may occur. They can appear from loose connections, from damage to the gas pipeline itself (corrosion, panic effects). Diagnostics involves checking the wall thickness of the gas pipeline pipe, the presence of corrosion. The gas pipeline can be laid not only underground, but aboveground and aboveground. According to paragraph 4.3 of SNiP 2.04.08-87 "Gas supply", the laying of external gas pipelines on the territory of settlements should be provided, as a rule, underground in accordance with the requirements of SNiP 2.07.01-89 *. Above ground and ground laying of external gas pipelines is allowed inside residential areas and courtyards, as well as on other separate sections of the route. Paragraph 4.22. * of the same SNiP provides that above-ground gas pipelines should be laid on separate supports, shelves and columns made of non-combustible materials and along the walls of buildings. At the same time, laying is allowed: on free-standing supports, columns, overpasses and a stack of gas pipelines of all pressures; along the walls of industrial buildings with premises of categories C, D and D - gas pipelines with a pressure of up to 0.6 MPa (6 kgf / cm2); on the walls of public buildings and residential buildings not lower than III-IIIa degree of fire resistance - gas pipelines with a pressure of up to 0.3 MPa (3 kgf / cm2); along the walls of public buildings and residential buildings of the IV-V degree of fire resistance - low-pressure gas pipelines with a nominal pipe diameter, as a rule, not more than 50 mm, and when gas pressure regulators are placed on the outer walls and other structures of these buildings - gas pipelines with a pressure of up to 0.3 MPa - in the areas before entering them into the regulators. The transit laying of gas pipelines is prohibited: along the walls of buildings of children's institutions, hospitals, schools and entertainment enterprises - gas pipelines of all pressures; along the walls of residential buildings - gas pipelines of medium and high pressure. According to clause 4.1* of the Code of Rules “Gas distribution systems. Updated version of SNiP 42-01-2002”, design, construction, overhaul, expansion and technical re-equipment of gas distribution and gas consumption networks should be carried out in accordance with gas supply schemes developed as part of the federal, interregional and regional gasification programs of the constituent entities of the Russian Federation in order to ensure the envisaged these programs of the level of gasification of housing and communal services, industrial and other organizations. The construction of gas distribution networks and the reconstruction of worn-out steel gas pipelines should be carried out: using mainly polymer pipes and fittings (for example, from polyethylene and its modifications, polyamides); with the installation of control and safety devices for each consumer; with the laying of gas pipelines in places of limited access. In gas consumption networks, the safety of gas use must be ensured by technical means and devices. When designing gas pipelines from polyethylene and steel pipes, it is allowed to provide for their connection to existing gas pipelines without pressure reduction. In accordance with clause 4.16*, the operability and safety of operation of gas distribution and gas consumption networks and LPG facilities must be maintained and maintained through maintenance and repair in accordance with operational documents, technical regulations, national standards and codes of practice approved by federal executive authorities, and other normative legal documents. The connection of gas pipelines without pressure reduction must be carried out using special equipment that ensures the safety of work according to the technologies and production instructions approved in the prescribed manner. As indicated in 5.1.2*, gas pipelines should be laid underground. In exceptional cases, above-ground laying of gas pipelines along the walls of buildings inside residential courtyards and quarters, as well as in certain sections of the route, including sections of crossings through artificial and natural barriers, when crossing engineering and technical support networks, is allowed. Such laying of gas pipelines may be envisaged with appropriate justification and carried out in places where access of unauthorized persons to the gas pipeline is restricted. To numerous requests from the plaintiff to the defendant about replacing the old underground gas pipeline with a gas pipeline along the facade of the building, the defendant replied that the diagnostics of the gas pipeline was carried out in 2010 by a specialized organization Kostromadiagnostika LLC, according to the conclusion, the gas pipeline is suitable for further operation. However, the conclusion itself was not made known. The presence of a gas pipeline on a land plot causes the establishment, in accordance with the Rules for the Protection of Gas Distribution Networks, approved by Decree of the Government of the Russian Federation of November 20, 2000 N 878, of a gas pipeline security zone, within which it is prohibited (clause 14 of the Rules): to build industrial facilities; arrange warehouses, dig and cultivate the soil with agricultural and reclamation tools and mechanisms to a depth of more than 0.3 meters., i.e. i.e. residents of the first floors of the house cannot attach balconies. The plaintiff asks to oblige the defendant to replace the expired underground gas pipeline with a ground one, along the facade of the house .; recover from the defendant the cost of paying the state duty and paying for legal services - 6 200 RUB.

Claimant Prokasheva T.A. and its representatives Shulepov A.B., Prokashev V.N. at the hearing supported the arguments and requirements of the claim. Additionally, it was explained to the court that the diagnostics of the gas pipeline did not meet the requirements of the standards, the submitted conclusion was not trusted, it was falsified, since in fact the state of the gas pipeline was not verified by the drilling method, their house was not indicated in the act. They believe that the underground gas pipeline violates their right as owners to use the land and to build balconies. It is also believed that since there was no opening of the land plot, they are afraid of corrosion on the gas pipeline, which poses a threat to life. An elevated gas pipeline is easier to control. They are not ready to bear the burden of paying for the replacement of the gas pipeline, because it is the property of Gazprom.

The representative of the defendant AO «Gazprom gazoraspredeleniye Kirov» by proxy Sannikov E.S. she did not recognize the claims, she explained to the court that the underground low-pressure gas pipeline laid in the city of Kirov at the following addresses: belongs to Gazprom Gas Distribution Kirov JSC, is a distribution gas pipeline for supplying natural gas. Due to the fact that the underground low-pressure gas pipeline, including at the address, was put into operation in 1972, at the request of Gazprom Gas Distribution Kirov JSC (formerly Kirovoblgaz JSC), technical diagnostics of the specified underground gas pipeline was carried out for assessing the compliance of the object with the requirements of industrial safety imposed on it by KostromaDiagnostika LLC in 2010. According to the results of the pit control during the examination, no damage was found to the welded joints of the gas pipeline, the insulating coating of the gas pipeline is good, there is no corrosion of the surface layer of the pipe metal. According to conclusion No. 17.2010/0006-5-3, the underground low-pressure gas pipeline complies with the industrial safety requirements imposed on it and is allowed for further operation. The period of safe operation of the gas pipeline has been extended until October 2020, taking into account the results of this opinion. After the expiration of the specified period, it is necessary to conduct an examination of industrial safety. Relocation of the underground low-pressure gas pipeline to the address is impractical, because according to conclusion No. 17.2010/0006-5-3, the specified underground low-pressure gas pipeline complies with the industrial safety requirements imposed on it and is approved for further operation. The removal of the gas pipeline to the facade of a residential building will contradict clause 4.7 of SP 42-101-2003, since the laying of gas pipelines on the territory of settlements is provided mainly underground. When the gas pipeline is moved to the facade of a residential building, there is no way to restrict the access of unauthorized persons to the gas pipeline and protect an indefinite circle of people from accidents and the consequences of these accidents. Due to the fact that the underground gas pipeline is a distribution gas pipeline, when the gas pipeline is moved to the facade (a complex of construction and installation works), for some time some of the residential buildings at the address will remain without gas supply services. Gazprom Gas Distribution Kirov JSC bears the burden of maintaining the said gas pipeline (operation, maintenance, diagnostics, repair, emergency dispatch support). In the event of the removal of a gas pipeline approved for further operation on the facade of a residential building, these costs must be reimbursed to the owner of the gas pipeline at the expense of the owners initiating the said removal. The presented act of technical research in the period from 07/08/2015 to 09/17/2015 confirms the inspection of the entire gas pipeline line, including the disputed house passing through the land plot, since the gas pipeline is a single object. in a lawsuit.

The representative of a third party - LLC UK "Paritet" Myshkin D.S. claims Prokasheva T.A. supported.

The court, after hearing the parties, examining the written evidence, came to the following.

I DECIDED:

In satisfaction of the claims Prokasheva T.A. to JSC "Gazprom gas distribution Kirov" Kirov on the obligation to replace the gas pipeline with expired service life refuse

The decision can be appealed to the Kirov Regional Court through the Oktyabrsky District Court of the city of Kirov within a month from the date of the final decision - 06 October 2015.

Judge S.A. Starodumova

Norms for the location and rules for the transfer of gas pipes in the kitchen

Most of the goodies on the tables appear with the participation of a natural gift - gas. Naturally, the owners of the house want the blue fuel to get into the kitchen unnoticed, without destroying the harmony, integrity of the design and style that has been thought out for months. Meanwhile, engineering networks are not a toy, you can’t joke with them, because in the pursuit of beauty you can lose the main thing - life. So, how and where should a gas pipe be installed in the kitchen: rules and regulations for handling the system.

If earlier people could not imagine life without water, now they don’t know how to exist without gas either.

To begin with, it is worth finding out under what circumstances gas pipes in the kitchen are operated. The use of blue fuel in such a room most often means the installation of a stove. It's time to read the terms of use. So, remember the main postulates:

gas stoves are allowed to be installed in kitchens with a height of 2.2 meters or more (if the ceiling in the room is sloping, then to install the stove, you should choose a place where it reaches the established norm);
the kitchen should be equipped with a window with a window so that during the day repairs can be carried out without artificial lighting, ventilating the room (the presence of a functioning ventilation duct is welcome);
between the slab and the opposite wall there must certainly be a passage with a width of 1 meter or more;
the ceiling and walls made of materials prone to burning, according to the norms, must certainly be covered with plaster;
the stove is allowed to be used in kitchens separated from the corridor by a reliable wall / partition and a door;
the layout of gas pipes in the kitchen should be done so that the distance between the walls and the stove is from 7 centimeters;
a branch to the plate is allowed only at the level of the connecting fitting;
the shut-off valve should be installed at a level of 1.5 meters from the floor and at a distance of 20 centimeters to the side of the stove;
for mounting the plate, it is permissible to use a special (heat-resistant - from 120 degrees) flexible sleeve and do not forget to change it, based on the recommendations specified in the product passport.

The handling standards are indicated mainly with already installed pipes and devices attached to them. If you plan to change, transfer, or even cut off the gas pipe in the kitchen, then let's move on.

This is how you can hide a fragment of the network if it bothers you - without any transfer

Pipeline Requirements

What to do if the gas pipe in the kitchen interferes, and you know for sure that you won’t calm down until you move it? Study the rules below and change the network configuration without violating the rules, of course.

Installation rules

To remove the gas pipe in the kitchen or move it to another place, you need to know the following:

it is impossible to lay the pipeline through the door or window;
it is forbidden to lead the gas system through the ventilation shaft;
access to pipes must always be open (you cannot know when an accident will occur, who will fix the breakdown, but this someone must accurately find where the pipeline is);
the length of the flexible fragments of the network should not exceed 3 meters;
the distance between the floor and the system should be from 2 meters;
the rigidity of the pipe joints is no less important than other standards;
the pipeline requires painting;
the intersections of the network with the walls must have a special "package" in the form of a construction case.

It's important to know! And the most important rule: when working with a network transporting blue fuel, turn off the gas before starting the process!

Clearly decide what you want, and even better - draw and show to the masters

Pipe transfer

The decision whether it is possible to cut or move the gas pipe in the kitchen will be up to the relevant services. You are only free to propose a redevelopment of the network and voice your own version. And professionals will tell you whether such changes are real, whether they will pose a threat to people's lives, and they will also tell you how much such an “upgrade” will cost you. Where to begin? Where to knock?

Any transfer of pipes must be coordinated with the relevant services.

Issuance of a permit

Remember the step-by-step instructions for preparatory actions and coordination of plans for the transfer of gas pipes:

Contacting the gas service according to the place of registration. It happens that you need to “knock” on some subsidiary structure of this organization: everything will be explained to you on the spot.
Making an application. You will be provided with a sample appeal, on the basis of which you must write applications on your own behalf on the topic of what changes you want to make (the application serves as the basis for the master to visit you).
Inspection of housing by a representative of the gas service. The master will listen to you, examine everything, check, make the correct calculations (subject to compliance with all standards). It is not a fact that at the same time the expert will reject your plan, it happens, especially with a diligent approach and the homeowner studying the norms, that the master does not have to correct anything.
Drawing up a budget. This, in fact, is done by the office you contacted.
Budget approval. When the plan is ready, it will be given to you in your hands so that you familiarize yourself with the documents and give your consent to carry out this kind of work.
Payment. If the estimate suits you, you should pay for this service. If not, then don’t be upset, it can be improved, you just tell the master what you don’t agree with, and he will find a compromise proposal.

Worth paying attention! If it is not possible / safe to make the network configuration according to the “scenario” you propose, the estimate proposed by the service does not suit you, then it’s too early to hang your nose. Buy or order a beautiful box for a gas pipe in the kitchen, and your problem will be solved, and beauty will be multiplied.

Remember to install taps to turn off the gas if you want to change the stove

Preparing for the process

If the estimate is agreed upon by you, then within 5 days (as a rule) a team will knock on your house, ready to move the pipes according to your wishes. Is it necessary to prepare for the arrival of the masters? If you want the work to be carried out quickly, efficiently, and your house is not damaged by the visit of workers, you should do the following:

contact the craftsmen and find out if you need to provide any consumables (so as not to run after them during the work of the team, frantically looking for someone of your own who will look after the apartment, because strangers still work);
free up space where it is planned to dismantle and install new pipes - workers must have unhindered access to the network;
cover all kitchen surfaces, appliances and other valuable items, because craftsmen will cut, cook, dust and litter (it is better to use non-flammable coatings as a material, for example, tarpaulin, burlap);
turn off the valve to stop the supply of blue fuel to the pipes.

Siphon connection simplifies the process of connecting elements

Work order

Of course, you will be interested to know how to cut the gas pipe in the kitchen and install it, because for sure you will want to control the process, or even risk doing the entire block of work yourself (it's up to you to decide).

So, get acquainted with the process in stages:

After shutting off the gas, blow through the pipes in order to remove all kinds of debris.
Cut off the extra fragment of the system.
Plug the hole that appears.
Make a hole in another place - where you plan to connect a new network segment (a drill is acceptable).
Weld the new structure to the gap.
Weld other parts, if provided by the project.
Install a faucet.
Seal the joints with tow.
Connect the device (stove, column).
Check the quality of work (if the transfer will be carried out by the gas service, ask the master for a certificate of completion).

One last thing: if it is not possible to move the pipes, come up with a design to hide them. Now there are a lot of materials on this topic, so luck will certainly smile at you.

And the last thing: gas pipes in the kitchen are not a toy, treat all work related to blue fuel with seriousness and responsibility.

Home → Useful information → Briefly about different things → House, cottage and gardening → Norms for gasification of a private house

Conducting gas to a private house or cottage is a technically difficult task.

The gasification process, starting with the collection of the necessary documentation and ending with the installation of equipment, is laborious, not very cheap and lengthy.

But the cost of equipment and services for the installation of a gas pipeline will pay for itself over time, since gas, as you know, is the most economical energy carrier.

There is a procedure for solving the problem of gasification and norms for gasification of a private house, the observance of which is mandatory for homeowners and organizations performing work.

The very first step in solving the problem of gasification of a private house will be to obtain the appropriate technical conditions. They are provided by the gas service department at the place of registration of the house. The term for the provision of technical specifications from the date of application, in accordance with applicable law, is no more than 10 days.

This service is provided free of charge.

The next stage of the task of conducting gas to a private house is the preparation of a package of design estimates. Such work is carried out by design organizations, sometimes by the gas supply organization itself.

After receiving the technical conditions, it is necessary to conclude an agreement with them to develop a project for supplying gas to a residential building.

The developed project is further coordinated with the technical department of the organization responsible for providing gas in a particular region. Upon completion of the coordination procedure, it remains to choose an installation organization that will directly conduct gas to the house.

In each case, when developing a gasification project for private houses, many circumstances are taken into account. Let's briefly review the main ones.

Pipeline selection

Gas pipelines, according to their placement relative to the surface of the earth, are divided into such types as aboveground and underground.

They differ in the way they are directly introduced into the room for the subsequent distribution of gas throughout the house (floors).

The price also depends on the type of pipeline. Thus, an underground gas pipeline is approximately 60% more expensive than a surface gas pipeline. But, despite this, the owners of houses distinguish it as preferable.

An underground gas pipeline has greater protection from environmental influences. It is more difficult to damage it mechanically. In addition, it has a long service life.

Aboveground gas pipelines also have positive features. As already noted, the cost of an aboveground gas pipeline is noticeably lower than an underground one. Aboveground pipelines are recommended in cases where the composition of the soil causes corrosion of the metal of the pipes, which will significantly affect the performance of the gas pipeline in the underground version. If the distance from the highway to the house is large, it is much easier to conduct gas above the ground.

Requirements for the selection of pipes

Polymer pipes are highly resistant to various chemical compounds. They are elastic, durable and reliable, almost seven times lighter than steel, do not conduct electricity, and therefore do not require additional protection against electrochemical damage before laying in the ground. Their installation is simple and convenient, and the warranty period is about 50 years. Such pipes are very often used in regions with low temperatures.

However, the introduction of pipes directly into the building, in accordance with the current norms for the gas pipeline, is carried out only from steel. The same rules apply to gas pipes inside the house.

How to move a gas pipe in an apartment: transfer rules and location tips

Polyethylene pipes must not be used in places where winter temperatures are below -50 degrees, in areas with high seismic activity. Do not use polyethylene pipes for ground gas pipelines, etc.

On the norms and rules for the installation of a gas pipeline

There are a number of rules that builders who perform installation work when conducting gas to the house must follow:

the optimal depth of laying a gas pipeline in the local area should be from 1.25 to 1.75 meters from the ground surface;
directly at the entrance to the building - from 0.75 to 1.25 meters;
you can enter the gas pipeline into the house through the wall or through the foundation;
the height of the room where it is planned to install a gas stove should be at least 2.2 meters;
without fail, the room must be equipped with a ventilation system with access to the street;
it is impossible to mount kitchen ventilation adjacent to living quarters.

Requirements for autonomous gasification of a private house

If it is impossible to conduct gas to a private house from the central highway, it is possible to gasify a private house by using imported gas - propane-butane cylinders, the volume of which can be 50 and 80 liters.

The volume of gas in such cylinders is enough to meet the household needs of a family of 4 people for 1 month.

Such cylinders should be stored in a designated place (preferably outside the living quarters) in a metal cabinet. This will protect the house from accidental gas leaks or unexpected fires.

It is necessary to attach a special pressure regulator to the cylinder, which should bring the indicator to normal, and only after that the gas will flow directly to the devices.

The entry points for the gas pipe must be provided at the stage of drawing up the project of the house.

The cylinder cabinet must be installed on a foundation, at least 0.2 m high, and also firmly attached to the wall of the house.

When laying the gas pipeline from the cabinet, the following requirements must be met:

the height of the pipeline should be at least 2.5 m from the ground;
the pipeline must be securely fastened to the walls of the building.
the pipeline should not cross window and door openings;

Balloon equipment will not cope with the task of heating a house, but if the stove is the only consumer of gas, then this will be the best option for a private house or cottage.

The installation of an autonomous gasification system will help to solve the issue of heating the house. And here specialists will come to the rescue, for example, the company "Nordstroy"(St. Petersburg), which has serious experience and performs work on the gasification of private and commercial, industrial facilities, maintenance of boilers and engineering networks.

About normative documentation

The building standards for gasification of a private house are set out in the regulatory documents that are valid today - these are SP 42-101-2003 and SNiP 2.07.01-89.

Gas distribution networks can be conditionally divided into external and internal.

Gasification, i.e., the construction of gas distribution stations and external networks in villages, towns and other settlements, is carried out by specialized organizations that have a license to carry out these works.

They are required to adhere to all the rules that are set out in the regulatory documents.

During the gasification of settlements, these organizations strictly comply with the requirements of both special building standards and regulatory documents of the Ministry of Emergency Situations and power engineers.

Internal networks are those networks that are located directly in the house along with gas equipment.

Standards for gasification of a private house every homeowner should know.

In particular, the above documents indicate that when gasifying a private house, it is necessary to adhere to the following standards:

When installing a boiler with a power of up to 60 kW, the height of the room from floor to ceiling must be at least 2.4 meters.
The glazing area of the room should be 0.03 m 2 per 1 m 3, but not less than 0.8 m 2.
If 1 (one) boiler is installed, then the area of the room must be greater than or equal to 7.5 m 2, if 2 (two) boilers - 15 m 2.
When installing more powerful boilers in the basement of a building, a gas alarm must be installed without fail.
When installing 2 burners, the volume of the kitchen must be greater than or equal to 8 m 3, and 4 burners - 15 m 3.

The process of gasification of a private house also includes the study of chimneys and hoods in case of possible accumulation of gas during the operation of gas equipment.

Gasification of a private house will solve many problems - this is not only cooking, but also heating, and the presence of hot water.

Gas equipment is practical and convenient to use, and gas supply is the most environmentally friendly compared to other types of fuel.

Company "Nordstroy" from St. Petersburg will help not only to quickly and efficiently connect gas to the house, but also draw up all the necessary documents, saving customers from wasting time on their supply and obtaining all permits.

MOSGAZ comment

Gas / Gasification and gas supply

How far from the outdoor gas pipe can the air conditioner be placed? We are publishing MOSGAZ's answer to this question.

Air conditioning on the facade of the house next to the outdoor gas pipe: what are the requirements for placement?

Question: Good afternoon! At what distance from the main external gas pipe running along the facade of the house can the outdoor unit of the air conditioner be installed?

Answer: Dear Hope! In response to your request dated October 31, 2014, MOSGAZ OJSC informs the following.

The installation of an air conditioner on the facade of a building in relation to a gas pipe is not regulated by regulatory documents.

According to section 5 of SP 42-102-2004 "Design and construction of gas pipelines from metal pipes", when laying a gas pipeline, it must be possible to inspect and repair it and exclude the possibility of mechanical damage.

Sincerely yours, Yury Evgenyevich Koloskov, First Deputy General Director of OAO MOSGAZ.

What should be the distance from the gas pipe to the building

Gas is the most affordable and therefore the most popular energy resource. It is used as fuel for the vast majority of heating systems and, of course, for kitchen stoves and ovens.

It is supplied in two ways: through the gas supply system or in cylinders.

Gas lines

The cost-effectiveness of this solution is obvious.

Firstly, a much larger number of objects are covered in this way, and secondly, it is impossible even to compare the volume of gas transmitted through pipes with what is supplied in cylinders. Thirdly, the level of safety of the gas pipeline is much higher.

For domestic needs, high-calorific gas is used, with a calorific value of about 10,000 kcal/Nm3.

The gas is supplied under various pressures. Depending on its size, communications are divided into three types.

Gas pipeline with low pressure - up to 0.05 kgf / cm2. It is being built to supply residential and administrative buildings, hospitals, schools, offices, and so on. Almost all urban utilities fall into this category.
Communications with medium pressure - from 0.05 kgf / cm2 to 3.0 kgf / cm2, are required during the construction of the main city boiler houses and as highways in large cities.
High pressure network - from 3.0 kgf/cm2 to 6.0 kgf/cm2. Arranged to provide industrial facilities. Even higher pressure, up to 12.0 kgf/cm2, is implemented only as a separate project with appropriate technical and economic indicators.

In large cities, a gas pipeline may include communication elements of low, medium, and high pressure. The gas is transmitted downstream from the higher pressure network to the lower one through regulatory stations.

Communication device

Gas pipes are laid in different ways. The method depends on the task and features of operation.

Underground communications are the safest way of laying and the most common. The laying depth is different: the gas pipeline transmitting wet gas should be placed below the freezing level of the soil, gas pipes moving the dried mixture - from 0.8 m below ground level. The distance of the gas pipeline to a residential building is standardized by SNiP 42-01-2002.
Transferring gas pipes in an apartment and a private house: are we ourselves with a mustache or is it better not to risk it?

The gas pipe can be steel or polyethylene.

Ground systems - allowed in case of artificial or natural barriers: buildings, waterways, ravines, and so on. A ground device is allowed on the territory of an industrial or large municipal building. According to SNiP, only steel gas pipelines are allowed for above-ground communications. The distance to residential facilities is not set. Pictured is an onshore gas pipeline.
Internal networks - the location inside the buildings and the distance between the walls and the pipeline is determined by the installation of consumer objects - boilers, kitchen equipment and so on. It is not allowed to lay gas pipelines in strobes: access to any section of the pipe must be free. For the organization of internal networks, steel and copper products are used.

In suburban areas, the construction of a ground version is commonplace. The reason is the cost-effectiveness of such a solution.

Permissible distances

SNiP 42-01-2002 determines the distance between the house and the gas pipe by the magnitude of the gas pressure. The higher this parameter, the greater the potential hazard of the gas pipeline.

A distance of 2 m is maintained between the foundation of the inhabited house and the low pressure gas pipeline.
Between gas pipes with an average value of the parameter and the structure - 4 m.
For the high pressure system, a distance of 7 m is set.

The distance between the house and the elevated structure is not regulated by SNiP. However, it establishes a security zone around the land gas pipeline - 2 m on each side. The zone must be highlighted. Accordingly, when building a house, compliance with this boundary should be taken into account.

Building rules regulate the placement of the gas pipe relative to the window and door opening - at least 0.5 m, as well as the distance to the roof - at least 0.2 m.

Hello! I really need your professional advice! The situation is as follows: on the privatized site there is a gasified house, we want to conduct gas to a newly built house in the depths of the site. It is possible to lay a gas pipeline in a straight line from the first house to the new one, but there is no distance of 1 m from the gas pipe to the fence and to the outbuildings of the neighboring non-privatized area.

How to move a gas pipe in an apartment and comply with all norms

We have a long-term dispute with a neighbor over the boundary, but I have an act of "Agreement and establishment of boundaries" by the Land Department (that part of the neighbor's outbuildings are on my territory). The problem is that the neighbor is an employee of Gorgaz. And the head of the technical department, being in collusion with her, refuses to lay the gas pipeline in a straight line (referring to the fact that there is no 1 m), and insists on laying the pipe around all my buildings. All over my yard! The boss refers to the standards of the underground gas pipeline, but we have it on the ground! What would you advise to do in this situation? It's a shame that the neighbor's gas pipeline partially passes through my territory (but this has been since 90, when my grandfather was the owner), that is, there is "not a word" about the meter, as well as a ground gas pipeline all over our street and there is no meter anywhere !

A man acquired a house as a property, and after some time it turned out that it was built in the zone of minimum safe distances of the main gas pipeline. And this is despite the presence of permits for construction and commissioning of the facility. Will the owner be required to demolish such a house? Recently, the Russian Armed Forces faced a similar case and gave an answer to the question posed. Let's consider the details.

The essence of the dispute

LLC "G" owns the main gas pipeline on a leasehold basis. According to the current legislation, the minimum allowable distance from a residential building to such a gas pipeline is 100 m. However, the cottage of citizen G.R. located at a distance of 98 m from the axis of the gas pipeline. The cottage village, together with the indicated cottage, was built by LLC "U" after the laying of the highway.

LLC "G" warned the developer LLC "U" that it would not agree on the construction, since the built-up area laid down in the project turned out to be in the zone of minimum safe distances of the main gas pipeline. The developer was asked to revise the project of the cottage settlement and coordinate it with the representatives of LLC "G", as well as to stop any construction work until the identified violations are eliminated. Since U LLC did not take any measures and built the house without the permission of the gas transportation organization, the latter filed a lawsuit against the owner of the house, G.R. and to the builder LLC "U" to eliminate the violations committed by demolishing the unauthorized construction at its own expense.

The court of first instance confirmed: the disputed facility is located in violation of the minimum distances from the axis of the gas pipeline, which poses a threat to the life and health of both G.R. himself and the citizens whose houses are located in the immediate vicinity. In addition, the structure of the defendant can be an additional catalyst and fire-spreading element in the event of an accident on the gas pipeline. In this regard, the court of first instance ordered G.R. demolish at his own expense a house located in the zone of the minimum allowable distances of the main gas pipeline, and refused to satisfy the claims against U LLC, since the latter is not the owner of the disputed building (decision of the Zelenodolsk City Court of the Republic of Tatarstan dated October 22, 2014 in case No. 33 -1941/2015).

The owner of the house G.R. filed an appeal with the court. He insisted that SNiP 2.05.06-85, which established the minimum distance from the axis of the pipeline to buildings and structures, was advisory in nature. In addition, the local self-government body of the city where the disputed facility is located knew about the presence and location of high-pressure gas pipelines, and, despite this, issued permits for the construction and commissioning of the facility. The court of second instance focused on the fact that the disputed building is located in the security zone only by its small part and at an angle to the gas pipeline. In addition, according to the appellate court, the plaintiff could choose another way to protect his interests - while the court did not indicate which one. Based on this, the Court of Appeal overturned the decision of the court of first instance and dismissed the claim (appellate ruling of the Judicial Collegium for Civil Cases of the Supreme Court of the Republic of Tatarstan dated March 5, 2015 in case No. 33-1941/2015).

Position of the RF Armed Forces

Disagreeing with the appeal ruling, OOO G filed a cassation appeal demanding that it be canceled and the decision of the court of first instance on the demolition at the expense of the owner of the building located in the zone of the minimum allowable distances of the main gas pipeline be upheld.

The Judicial Collegium for Civil Cases of the Armed Forces of the Russian Federation noted: in violation of the requirements of Part 1 of Art.

4 tbsp. 198 of the Code of Civil Procedure of the Russian Federation, the decisions of the lower courts do not contain motivated conclusions regarding how the courts determined the minimum allowable distance from the axis of the gas pipeline to a residential building. Buildings, structures and structures built closer than the minimum distances established by building codes and rules to gas supply system facilities are subject to demolition at the expense of legal entities and individuals who have committed violations (para.

Gas pipe in the kitchen: norms and rules for installing an engineering network

4 tbsp. 32 of the Federal Law of March 31, 1999 No. 69-FZ "On Gas Supply in the Russian Federation").

In addition, the court of cassation noted that the court of appeal, referring to the insignificance of the violation of the minimum allowable distances from the axis of the gas pipeline to G.R. .

According to the Judicial Collegium for Civil Cases of the Armed Forces of the Russian Federation, the violations committed by the courts are significant, affect the outcome of the case, and without their elimination it is impossible to restore and protect the violated rights and legitimate interests of the applicant. In this regard, the appeal ruling of the Judicial Collegium for Civil Cases of the Supreme Court of the Republic of Tatarstan of March 5, 2015 is subject to cancellation with the direction of the case for a new consideration to the court of appeal (Determination of the Judicial Collegium for Civil Cases of the Supreme Court of the Russian Federation of January 19, 2016 No. 11- CG15-33).

In the latest Judicial Practice Review of the Armed Forces of the Russian Federation, the highest judicial body clearly stated: buildings and structures built closer than the minimum distances to gas supply facilities established by building codes and rules are subject to demolition (Review of Judicial Practice of the Armed Forces of the Russian Federation dated July 6, 2016 No. 2). This means that when purchasing residential buildings, owners need to be especially careful, because building permits and putting an object into operation do not guarantee that the building meets all mandatory norms and legal requirements. However, if technical violations were nevertheless committed, the owner may try to recover the losses caused to him from the guilty person, for example, from the developer or the authority that issued permits (as the applicant did in case No. 4G-119 / 2015, considered by the Presidium of the Supreme Court Republic of Tatarstan April 8, 2015).

We draw your attention to the fact that this decision could be challenged in a higher court and canceled

homeowners association st. Kommunisticheskaya, 64 (hereinafter referred to as the Partnership) filed a lawsuit with the Arbitration Court of the Komi Republic against Gazprom Gas Distribution Syktyvkar Open Joint Stock Company represented by a branch in Syktyvkar (Syktyvkarmezhraygaz trust) (hereinafter referred to as the Company). The subject of the claims (taking into account their clarification) was the settlement of disagreements that arose during the conclusion of a contract for the maintenance, repair of external and intra-house gas supply networks of an apartment building and emergency dispatch services dated April 1, 2012 N 96. The plaintiff asked to accept paragraphs 3.1.6, 3.2.1, 3.2.4, 4.2, 5.3, 5.4, 5.5, 5.6, 7.2 and Appendix No. 3 to the agreement "Act of delimitation of operational responsibility" in the version proposed by him.
Among other things, the disagreements of the parties concerned the determination of the boundaries of the operational responsibility of the Partnership for the maintenance of gas supply networks. The partnership believed that the border runs along the outer wall of the apartment building. There are independent points of connection to the gas distribution network on the gas pipeline for each entrance. At each such point, a shut-off device is installed.
The company insisted that the border of the operational responsibility of the parties is located on a disconnecting device installed outside at the point of connection of the inlet gas pipeline adjacent to the house to the external underground low-pressure gas pipeline with a diameter of 219 mm, laid through the courtyard. Thus, the introductory gas pipeline laid along the facade of an apartment building refers to the common property of the owners of residential and non-residential premises of this building.
The court of first instance, by decision of 03.08.2012, left unchanged by the decision of the Second Arbitration Court of Appeal of 02.11.2012, adopted paragraphs 3.1.6, 3.2.4, 5.5, 5.6 and 7.2 as amended by the defendant, paragraph 3.2.1 and Appendix No. 3 to agreement as amended by the plaintiff, paragraphs 4.2, 5.3 and 5.4 outlined in his version. Proceedings on disagreements under clause 1.1 of the contract and Appendix No. 2 to the contract were terminated by the court.
Accepting Appendix No. 3 as edited by the plaintiff, the courts proceeded from the fact that shut-off devices are installed in each entrance. The external gas pipeline networks running along the facade of the building from the gas distribution network to the shut-off shut-off devices installed in the entrances do not belong to the Partnership and were not transferred to its balance sheet. Consequently, the border of the operational responsibility of the parties is located in the places of network tie-ins on the outer border of the wall of an apartment building.
In passing judicial acts, the courts were guided by:
- - Articles 290, 421, 422, 445 and 446 of the Civil Code of the Russian Federation;
- - Article 36 of the Housing Code of the Russian Federation;
- - Articles 2 and 36 of the Federal Law of December 30, 2009 N 384-FZ "Technical Regulations on the Safety of Buildings and Structures";
- - paragraphs 3, 5 and 9 of the Rules for the maintenance of common property in an apartment building, approved by Decree of the Government of the Russian Federation of August 13, 2006 N 491 (hereinafter - Rules N 491);
- - Clause 21 of the Rules for the supply of gas to meet domestic needs of citizens, approved by Decree of the Government of the Russian Federation of July 21, 2008 N 549 (hereinafter - Rules N 549);
- - paragraphs 2, 4 and 26 of the Procedure for the maintenance and repair of in-house gas equipment in the Russian Federation, approved by order of the Ministry of Regional Development of Russia dated June 26, 2009 N 239 (hereinafter - Procedure N 239).
Disagreeing with the judicial acts, the Company filed a cassation appeal with the Federal Arbitration Court of the Volga-Vyatka District, in which (subject to clarification) it asks to change the decision dated 03.08.2012 and the decision dated 02.11.2012 and accept Appendix No. defendant.
According to the applicant, the conclusions of the courts were accepted without taking into account the provisions of paragraph 9 of Rules N 491, section 1 of the Safety Rules for gas distribution and gas consumption systems, approved by the Decree of the Gosgortekhnadzor of Russia dated March 18, 2003 N 9 (hereinafter referred to as Rules N 9), and OST 153-39.3-051 -2003, approved by order of the Ministry of Energy of the Russian Federation dated June 27, 2003 N 259. The outer boundary of the gas supply networks that are part of the common property is the junction of the first locking device with the external gas distribution network. The gas distribution network is the technological complex of the gas distribution system up to the inlet gas pipeline to the gas consumption facility. The inlet gas pipeline includes a section of the gas pipeline from the disconnecting device installed outside at the entrance to the building to the internal gas pipeline. The internal gas pipeline is a gas pipeline laid inside the building from the inlet gas pipeline to the installation site of gas-using equipment. Thus, the owners of multi-apartment residential buildings (or the contractors of public services, which is the plaintiff) must maintain both the internal and the introductory gas pipeline. The version of Appendix No. 3 proposed by the Company complies with the specified legal norms.
The applicant believes that the courts unreasonably considered the disagreements that were not present at the conclusion of the contract. In support of his arguments, the defendant points out that when concluding the contract, the plaintiff did not indicate that he had disagreements on Appendix No. 3 to the contract. The specified appendix was signed by the Partnership without disagreement.
The Partnership in response requested that the disputed judicial acts be left in force and rejected the arguments of the cassation appeal, referring, among other things, to judicial practice in a similar dispute (case No. A29-282 / 2009). According to the Partnership, the external (facade) gas pipeline is not the common property of the residents of the apartment building and the plaintiff should not maintain it.
At the court session, the applicant's representative supported the arguments of the cassation appeal, referred to the various practices emerging in the consideration of similar cases, pointing in particular to case No. А29-3711/2012, considered in two instances.
The plaintiff, duly notified of the time and place of the consideration of the complaint, did not appear at the session of the court of cassation. The case was considered in his absence.
At the hearing, in accordance with Article 163 of the Arbitration Procedure Code of the Russian Federation, a break was announced from 03/01/2013 to 03/05/2013.
The legality of the adopted judicial acts was verified by the Federal Arbitration Court of the Volga-Vyatka District in the manner prescribed in Articles 274, 284 and 286 of the Arbitration Procedure Code of the Russian Federation.
In accordance with Article 286 of the Arbitration Procedure Code of the Russian Federation, the arbitration court of the cassation instance verifies the legality of decisions, rulings adopted by the arbitration court of the first and appellate instances, establishing the correctness of the application of substantive law and procedural law in the consideration of the case and the adoption of appealed judicial acts and based on the arguments, contained in the cassation complaint and objections to the complaint.
As follows from the case file, the plaintiff manages a multi-apartment residential building N 64 on Kommunisticheskaya Street in the city of Syktyvkar.
The company is a specialized organization for the maintenance of in-house gas equipment.
To settle the relationship for 2012, the plaintiff sent to the defendant a draft maintenance contract dated April 1, 2012 N 96. The subject of the contract was maintenance, repair of external and intra-house gas supply networks of an apartment building managed by the Partnership, and emergency dispatch services.
From the correspondence of the parties and the available protocols of disagreements, it follows that the parties did not come to an agreement on a number of terms of the contract, which was the reason for applying to the court with this claim.
The disagreements of the parties remaining after the consideration of the case in the courts of two instances are as follows:

The boundaries of operational responsibility are clearly indicated by the parties in the diagrams (case sheets 19 and 51, volume 1).
It follows from the explanations of the parties and the indicated diagrams that the disputed section of the gas pipeline is intended exclusively for gas supply to the multi-apartment residential building No. 64 on Kommunisticheskaya Street, runs along the facade of this house to the junction with an underground low-pressure gas pipeline with a diameter of 219 mm, laid along the courtyard of the same street.
Having studied the materials of the case, having studied the arguments of the cassation appeal and the response to it, the court of cassation adopted a decision based on the following.
In cases where disagreements that arose during the conclusion of the contract are referred to the court on the basis of Article 445 of the Civil Code of the Russian Federation or by agreement of the parties, the terms of the contract on which the parties had disagreements are determined in accordance with the decision of the court (Article 446 of the Civil Code of the Russian Federation).
According to paragraph 4 of Article 421 of the Civil Code of the Russian Federation, the terms of the contract are determined at the discretion of the parties, except when the content of the relevant condition is prescribed by law or other legal acts (Article 422 of the Civil Code of the Russian Federation).
By virtue of paragraph 1 of Article 422 of the Civil Code of the Russian Federation, the contract must comply with the rules binding on the parties established by law and other legal acts (imperative norms) in force at the time of its conclusion.
The owners of apartments in an apartment building own the common premises of the house, the supporting structures of the house, mechanical, electrical, sanitary and other equipment outside or inside the apartment, serving more than one apartment, on the basis of common share ownership. The owner bears the burden of maintaining the property belonging to him, unless otherwise provided by law or contract (Article 210, Clause 1 of Article 290 of the Civil Code of the Russian Federation).
The homeowners association is the executor responsible for maintenance of in-house engineering systems, and is obliged to independently or with the involvement of other persons maintain the common property of an apartment building, including in-house engineering systems, using which utility services are provided to the consumer. The norms obliging the contractor to maintain in-house engineering systems were contained in the Rules for the provision of public services to citizens, approved by Decree of the Government of the Russian Federation of 05.23. users of premises in apartment buildings and residential buildings (clauses 21, 31), approved by Decree of the Government of the Russian Federation of 05/06/2011 N 354 (hereinafter - Rules N 354).
In-house engineering systems are defined as engineering communications (networks), mechanical, electrical, sanitary and other equipment designed to supply utility resources from centralized engineering networks to in-house equipment. Centralized engineering and technical support networks are a set of pipelines, communications and other structures designed to supply utility resources to in-house engineering systems (paragraph 2 of Rules N 354).
In accordance with paragraph 5 of Rules N 491, the common property includes in-house engineering gas supply systems, consisting of risers, branches from risers to the first disconnecting device located on branches from risers, these disconnecting devices, the first shut-off and control valves on the outlets of intra-apartment wiring from risers, as well as mechanical, electrical, sanitary and other equipment located on these networks.
By virtue of paragraphs 2 - 4, 8 of Order N 239 and paragraph 3 of Regulation N 549, the structure of in-house gas equipment includes gas pipelines of an apartment building connected to a gas distribution network or to a tank or group cylinder installation, providing gas supply to the point of connection of gas-using equipment, as well as gas-using equipment and gas meters. The maintenance of the intra-house gas equipment of apartment buildings in good and efficient technical condition is carried out by carrying out a set of works for its maintenance, which include maintenance and repair of external and internal house gas pipelines of the gas consumption network.
As a general rule, the outer boundary of the engineering networks that are part of the common property is the outer boundary of the wall of an apartment building; the boundary of operational responsibility is the junction of the collective (common house) metering device with the corresponding engineering network included in the apartment building (paragraph 8 of Rules N 491).
A special rule has been established for gas supply networks: the outer boundary of gas supply networks that are part of the common property is the junction of the first locking device with the external gas distribution network (paragraph 9 of Regulation N 491).
The definition of various sections of the gas pipeline is given in Section 1 of the Safety Rules for Gas Distribution and Gas Consumption Systems (approved by Decree of the Gosgortekhnadzor of the Russian Federation dated March 18, 2003 N 9), as well as in paragraph 7 of the Technical Regulations on the Safety of Gas Distribution and Gas Consumption Networks (approved by Decree of the Government of the Russian Federation dated 29.10. 2010 No. 870).
So the gas distribution network is defined as a technological complex of the gas distribution system, consisting of external gas pipelines of settlements from the outlet shut-off device of the gas source to the inlet gas pipeline to the gas consumption facility. The gas distribution network is a single production and technological complex, which includes external gas pipelines, structures, technical and technological devices located on external gas pipelines, and is designed to transport natural gas from a shutdown device installed at the outlet of a gas distribution station to a shutdown device located at the border of the gas distribution network and the gas consumption network (including the gas consumption network of residential buildings).
The gas consumption network is a single production and technological complex, which includes external and internal gas pipelines, structures, technical and technological devices, gas-using equipment, located at one production site and designed to transport natural gas from a disconnecting device located on the border of the gas distribution network and the network gas consumption, to a shut-off device in front of gas-using equipment.
Inlet gas pipeline - a section of a gas pipeline from an externally installed disconnecting device at the entrance to the building, when installed outside, to an internal gas pipeline, including a gas pipeline laid in a case through the wall of the building.
Internal gas pipeline - a gas pipeline laid from the outer edge of the external structure of the building being gasified to the point of connection of gas-using equipment located inside the building.
Thus, the operational responsibility of the utility service provider for servicing the gas supply networks of an apartment building extends to the point of connection with the gas distribution network. At the same time, the introductory and internal gas pipelines are not sections of the gas distribution network. Essentially, both are designed to supply gas to a separate building and refer to an in-house engineering system designed to supply gas from a centralized gas distribution network to in-house equipment. The house engineering system is part of an apartment building.
The installation of an introductory gas pipeline in an outdoor version (along the facade of the building), in contrast to the laying of other utility supply systems, is due to the characteristics of the utility resource (gas) and safety requirements.
The parties did not dispute the fact that the gas distribution network is an underground low-pressure gas pipeline with a diameter of 219 mm, laid along the courtyard territory of Kommunisticheskaya Street in the city of Syktyvkar. Near the end of the apartment building N 65 on Kommunisticheskaya Street, the underground gas pipeline has an exit to the outside and is connected to the introductory gas pipeline. At the junction there is a locking device - the first between the plaintiff's network and the defendant's network. This information is confirmed by the diagrams attached by the parties to the acts of delimitation of operational responsibility. It follows that, in accordance with paragraph 9 of Rules N 491, the border of the operational responsibility of the parties in the disputed area should pass at the site of the tie-in into the underground low-pressure gas pipeline with a diameter of 219 mm, laid along the yard territory of Kommunisticheskaya Street in the city of Syktyvkar, that is, as indicated in the wording of the Society .
Based on the foregoing, the district court cannot agree with the conclusion of the courts of first and appeal instances that determined the operational boundary in the wording proposed by the Partnership.
The courts of first and second instance correctly established the factual circumstances relevant to the case, but incorrectly applied paragraph 9 of Rules No. 491 and the indicated legal norms determining the designation of sections of the gas pipeline, which, by virtue of paragraph 2 of part 1 of article 287, part 1 and paragraphs 1 and 3 Part 2 of Article 288 of the Arbitration Procedure Code of the Russian Federation is the basis for the cancellation of the contested judicial acts.
Shut-off shut-off devices installed between the inlet and internal gas pipelines are not the first shut-off devices with an external gas distribution network.
The Company did not need to prove the fact of the transfer of the introductory gas pipeline to the balance sheet of the Partnership, since this section of the network belongs to the in-house engineering gas supply system by definition and is part of the common property.
Among other things, in the wording of the plaintiff, the "introductory (facade) low-pressure gas pipeline d = 108/76/57", laid along the wall of the house, is listed as a transit one. At the same time, it does not follow from the scheme attached by the Partnership that gas through the introductory gas pipeline is in transit.
The cassation appeal is subject to satisfaction.
By virtue of Articles 110 and 112 of the Arbitration Procedure Code of the Russian Federation, the costs of the state fee for the consideration of the case in the courts of appeal and cassation in the amount of 2000 rubles are charged to the Partnership.
Guided by paragraph 2 of part 1 of article 287, part 1, paragraphs 1 and 3 of part 2 of article 288 and article 289 of the Arbitration Procedure Code of the Russian Federation, the Federal Arbitration Court of the Volga-Vyatka District

decided:

to satisfy the cassation appeal of the open joint-stock company Gazprom Gas Distribution Syktyvkar, to amend the decision of the Arbitration Court of the Komi Republic of 03.08.2012 and the decision of the Second Arbitration Court of Appeal of 02.11.2012 in case N A29-4089 / 2012 in the part relating to the settlement of disagreements between the parties on Appendix N 3 to the contract.
Adopt Appendix No. 3 to the agreement "The act of delimitation of operational responsibility" as amended by the defendant: "The boundaries of the operational responsibility of the parties are the red lines of demarcation at the point of insertion into the underground low-pressure gas pipeline d - 219 mm, laid along the courtyard territory of Kommunisticheskaya St. in the city of Syktyvkar; internal networks gas supply to the places of tie-ins of intra-apartment gas pipelines into risers".
Collect from the homeowners association st. Communist, 64 in favor of the open joint-stock company "Gazprom Gas Distribution Syktyvkar" represented by a branch in the city of Syktyvkar (trust "Syktyvkarmezhraygaz") 2000 rubles of the state fee for the consideration of the case in the court of cassation.
Issue a writ of execution to the Arbitration Court of the Komi Republic.
The decision of the arbitration court of the cassation instance shall enter into force from the date of its adoption.

Aboveground gas pipelines should be laid on free-standing supports, shelves and columns made of non-combustible materials or along the walls of buildings. In this case, laying is allowed:

On free-standing supports, columns, racks and whatnots - gas pipelines of all pressures;

On the walls of industrial buildings with premises related to fire hazard to categories D and D - gas pipelines with a pressure of up to 0.6 MPa;

On the walls of public and residential buildings at least 3 degrees of fire resistance - gas pipelines with a pressure of up to 0.3 MPa;

On the walls of public buildings and residential buildings of 4-5 degrees of fire resistance - low-pressure gas pipelines with a nominal pipe diameter of not more than 50 mm. The height of gas pipelines along the walls of residential and public buildings should be taken in agreement with the operating organization.

It is prohibited to lay transit gas pipelines:

On the walls of buildings of children's institutions, hospitals, sanatoriums, cultural and entertainment, leisure and religious institutions - gas pipelines of all pressures;

On the walls of residential buildings - gas pipelines of medium and high pressure.

The connection of underground steel gas pipelines-inlets with the riser of the above-ground (basement) input must be welded using bent or sharply bent bends. Welded butt joints in sections of underground gas pipelines-inlets must be checked by non-destructive testing methods.

High pressure gas pipelines up to 0.6 MPa are allowed to be laid along the walls, above the windows and doorways of one-story and above the windows of the upper floors of industrial buildings with premises classified as fire hazard categories D and D, as well as buildings of separate boiler houses.

It is not allowed to provide detachable connections and shut-off valves on gas pipelines under balconies and under window openings of residential and public buildings.

In a free area outside the passage of vehicles and the passage of people, it is allowed to lay gas pipelines on low supports at a height of at least 0.5 m, provided that one or more pipes are laid on the support. Gas pipelines at the places of exit from the ground should be enclosed in cases, the above-ground part of which should be at least 0.5 m. The end of the above-ground parts of the cases must be sealed with bitumen to prevent atmospheric precipitation from entering the annulus.

Distance to buildings and structures see table

In places where people pass, the height of the gas pipeline on supports is 2.2 m.

When laying a gas pipeline on supports closer than 2 m to the edge of the carriageway, a protective fence must be provided. The minimum distance of the protective gas pipeline to buildings must be at least 2 m. The gas pipelines are fastened to the supports using clamps.

Permissible spans between supports:

Pipe d- 20mm - 3 m

25mm - 3.5m

The laying of the gas pipeline along the walls is carried out using brackets according to the series 5.905-8 (Fastening the gas pipeline along the walls of the building). The distance between gas pipelines and walls should provide easy access for inspection and repair.

To combat corrosion, metal structures and pipes are painted twice with a preliminary application of a primer.

insulating flanges. Purpose and place of installation.

Insulating flange connection (IFS). Protection of gas pipelines with the help of IFS and inserts lies in the fact that the gas pipeline is divided into separate sections, due to which the conductivity of the pipe decreases, and at the same time the current flowing through the gas pipeline decreases and the solution of the issue of their protection is simplified.

The installation of the EIF at the inputs provides for the impossibility of electrical contact between the house and the gas pipeline. Installation of EIF on gas pipelines - inputs to the house are not higher than 2.2 m (usually 1.6-1.8 m from the ground for ease of maintenance).

Flange connections when installing gate valves, compensators must be shunted with permanent jumpers.

Placement of disconnecting devices on the gas pipeline.

Disconnecting devices on gas pipelines should be provided for:

At the inputs of residential, public, industrial buildings, in front of outdoor gas-consuming installations (mobile boilers, bitumen-digesting boilers, kilns for drying sand and firing building materials, etc.)

At the inputs to the hydraulic fracturing, at the outputs from the hydraulic fracturing with looped gas pipelines in systems with two or more hydraulic fracturing;

On branches of inter-settlement gas pipelines to settlements or enterprises;

On branches from gas distribution pipelines to individual microdistricts, quarters and individual groups of residential buildings;

For sectioning distribution gas pipelines of medium and high pressure for the possibility of performing emergency and repair work;

When gas pipelines cross water barriers, as well as one thread with a width of a water barrier with a low water horizon of 75 m or more;

When gas pipelines cross railways of the general network and highways of categories 1 and 2, disconnecting devices should be placed:

In front of the territories of industrial, municipal or other enterprises.

Disconnecting devices on external gas pipelines should be placed in wells, ground fireproof cabinets or fences, as well as on the walls of buildings. Well-free underground installation of disconnecting devices connected by welding, designed for well-free installation and not requiring maintenance is allowed.

Disconnecting devices intended for installation on the walls of buildings should be placed at distances from doorways and opening window openings of at least, m:

For low pressure gas pipelines - 0.5 m;

For gas pipelines of medium pressure horizontally - 1.0 m;

For high pressure gas pipelines up to 0.6 MPa horizontally -3.0 m.

Distances from disconnecting devices placed on the walls of buildings on the gas pipeline to receiving devices for supply ventilation must be at least 5 m horizontally. When the disconnecting devices are located at a height of more than 2.2 m

platforms made of non-combustible materials with stairs should be provided.

Purpose, device of shut-off and control valves?

Industrial pipeline fittings are:

1. shut-off

2. regulating

3. safety

4. control

Shut-off valves are designed to turn on and off individual sections of pipelines during operation. It includes taps, valves, valves.

Control valves are designed to change the pressure or temperature, or the flow rate of the transported medium.

Safety fittings are designed to protect pipelines, gas equipment, tanks from excessive

high pressure, as well as to maintain the required pressure in the pipeline.

Shut-off valves must be airtight in relation to the external environment. Valves, cocks, gate valves and rotary locks provided for gas supply systems as shut-off valves (shut-off devices) must be designed for hydrocarbon gases. The tightness of the gates must correspond to class 1 according to GOST 9544.

Valves and butterfly valves must have rotation stops and position indicators "open-closed."

Stop valves are made of gray cast iron, ductile iron, carbon steel, copper-based alloys.

Shut-off valves in accordance with GOST 4666 must be marked on the body and have a distinctive color. The marking must contain the manufacturer's trademark, conditional or working pressure, conditional passage and flow direction indicator, if necessary.

KPO on underground gas pipelines. Terms of inspection of gas pipelines. Paperwork.

Underground gas pipelines (made of metal and polyethylene pipes) in operation must be subject to technical inspection, incl. and complex instrumental examination. KPO, with the help of devices according to specially developed instructions, and if necessary, drilling is also carried out. During the technical examination

gas pipelines, the actual location of gas pipelines, the state of structures and equipment on them, tightness, the state of the protective coating and electrochemical protection should be determined.

When performing KPO, the following are checked:

location and, if necessary, the depth of the gas pipeline;

tightness of the gas pipeline;

continuity and condition of the protective coating.

Technical inspection of underground steel gas pipelines is carried out:

with a duration of operation up to 25 years - at least 1 time in 5 years. The first one a year after commissioning;

when operating for more than 25 years and before the expiration of the depreciation period of operation - at least 1 time in 3 years;

when they are included in the overhaul or replacement plan, as well as with a protective coating below the “highly reinforced” type - at least 1 time per year.

Extraordinary KPO of gas pipelines must be carried out:

If the service life exceeds for steel gas pipelines - 40 years, for p / et - 50 years;

If leaks or ruptures of welded joints, through corrosion damage are detected;

When the “gas pipeline-ground” potential drops to values below the minimum allowable, subject to a break in the operation of electrical protective installations for more than 1 month - in the zones of influence of stray currents and more than 6 months - in other cases provided for by DSTU B V.2.5-29:2006 " Engineering equipment of houses and structures. External networks and facilities. Gas supply systems. Underground steel gas pipelines. General requirements for corrosion protection".

On gas pipelines with a protective coating lower than the "highly reinforced" type, in addition to KPO, control drilling should be carried out to determine the condition of the pipes and the quality of the welded joints. Technical inspection of the condition of polyethylene gas pipelines is carried out within the time limits established for steel gas pipelines.

At KPO, a worksheet of 2 copies is compiled, one is given to the foreman of the network section.

Drilling on the gas pipeline. Drilling assignment. The order of the work. Formulation of documentation.

Inspection of underground steel gas pipelines in order to determine the state of the protective coating, where the use of devices is hindered by industrial interference, is carried out by opening control pits on gas pipelines with a length of at least 1.5 m every 500 m.

The places for opening control pits, their number in zones of industrial interference are determined by the gas enterprise or the enterprise operating the gas facilities on its own.

For visual inspection, selected areas are subject to the greatest corrosion hazard, the intersection of gas pipelines with other underground utilities, condensate collectors. At the same time, at least one pit should be opened for each kilometer of distribution gas pipelines and for every 200 m - a yard or intra-quarter gas pipeline, but at least one pit per passage, yard or quarter.

Checking the tightness and detection of gas leaks from underground gas pipelines during the period of soil freezing, as well as in areas located under improved road surfaces, should be carried out by drilling wells (or pinning) followed by taking air samples from them.

On distribution gas pipelines and inlets, wells are drilled at the joints. In the absence of the location of the joints, wells should be drilled every 2 m.

Their drilling depth in winter should not be less than the freezing depth of the soil, in the warm season it should correspond to the pipe laying depth. Wells are laid at a distance of at least 0.5 m from the gas pipeline wall.

When using highly sensitive gas detectors, it is allowed to reduce the depth of wells and place them along the axis of the gas pipeline, provided that the distance between the top of the pipe and the bottom of the well is at least 40 cm.

The use of open fire to determine the presence of gas in wells is not allowed.

Pit inspection of polyethylene gas pipelines is carried out only at the installation sites of steel inserts.

For 1 km of gas distribution pipelines and for each quarterly distribution, at least 1 insert is checked. To be able to inspect the joints of the joints of a polyethylene gas pipeline with a steel insert, the length of the pit should be 1.5-2 m. The opening of the pits is carried out using mechanisms or manually. Checking the insulation and metal of steel inserts must be carried out at least once every 5 years.

Based on the results of a technical inspection of steel and polyethylene gas pipelines, a protocol should be drawn up, in which, taking into account the identified defects and an assessment of the technical condition, a conclusion should be made on the possibility of further operation of the gas pipeline, the need for the timing of its repair and replacement. Information about the work performed and the results of the survey is entered in the passport of the gas pipeline.
