Everything about the distance from the gas pipe to other elements and buildings. How to correctly determine the distance from a gas tank to a residential building: we choose a suitable place on the Snip gas pipeline section, the distance from a private house

Hello dear readers. If there is a gas pipe in the kitchen, there are special standards for it. This is the distance from surfaces, and from household appliances. Competent installation of gas pipes throughout the apartment is also important.

Housing standards

The gas pipeline is installed in the apartment according to a previously developed plan. But even before that, it is necessary to determine the operating conditions of the gas pipeline. So, if gas pmi 2013 units function in the kitchen, it will become an indispensable element for them. Its presence in the boiler room is a guarantee of heat throughout the house.

According to the positions of the gas pipe in the kitchen and apartment, the norms are as follows:

1. No installation in residential premises and ventilation shafts.
2. Intersection with an opening for windows and doors is unacceptable.
3. Laying in hard-to-reach areas is prohibited. For example, behind a designer finish on the wall. Gas appliances must be easily and quickly accessible in case of malfunctions.
4. The minimum distance of the gas pipe from the floor is 2 m.
5. When using a pipe with thin walls, the length of the flexible communication components should not exceed 3 m. The density of the connections of the network elements is also of great importance.
6. Installation is allowed only in those rooms where the minimum ceiling height is 220 cm. And these rooms must be well ventilated.
7. The kitchen should not be provided with ventilation affecting the living quarters.
8. Wall and ceiling surfaces close to gas appliances must have a special coating of non-combustible plaster. If there is no such coating on the wall, it must be isolated from gas appliances using a metal sheet. Its suitable density is 3 mm.

Private house question

To lay in a private house, you also need to know the rules. To begin with, gasification here begins with the notification of the local gas organization and the planned work. It provides a technological condition that determines the algorithm for constructing a gas pipeline. A technical issue is being resolved. A personal development is being created for the gasification of a certain area. Also, a warrant for the installation of a gas pipeline is issued by the traffic police.

If the neighboring houses are already provided with gas, it is only necessary to connect the pipes in a particular area to the main network. The working pressure factor is also important here. Its parameter in the main pipes determines the choice of pipes for passing into the house.

The preferred gas source determines the gas supply technology: centralized or autonomous.

Also, gas pipelines can follow to private houses underground or above it.

And the norms for conducting a pipe to the kitchen in a private house are identical to the points in the housing issue.

Installation standards

The rules and regulations for installing a gas pipe in the kitchen are as follows:

1. Before work, the main valve is closed.
2. The gas pipeline is blown if the pipe is transferred.
3. Provided pipe fasteners to the wall. These are special clamps and staples.

The type of fastener is determined by the length and diameter of the pipes.

1. If there are electrical cables near the pipes, then the minimum distance here should reach 25 cm. And the gas equipment is 50 cm away from the electrical panel.
2. The location near the cooling equipment is unacceptable. In this matter, the owners often make mistakes. Is it possible to put a refrigerator near a gas pipe? It is forbidden. So the refrigerator radiator can quickly overheat, and the device itself will become faulty.
3. The minimum distance from the gas pipe to the stove is formed as follows: a branch to it goes only on the line of the connecting fitting. The shut-off valve is placed 150 cm from the floor and 20 cm from the side of the stove. The installation of the cash advance businesses slab takes place using a heat-resistant flexible sleeve.
4. Work should be carried out in a room with stable ventilation and natural light.
5. The minimum ceiling height is 220 cm.
6. The slab and the opposite wall must be separated by at least 100 cm.
7. Surfaces near pipes and slabs are covered with fire-resistant material - plaster.
8. The pipes are bred so that the plate is 7-8 cm from the walls.
9. The stove is operated only in the kitchen, which has a fence from the corridor: a wall or partition and a door.
10. The height of the gas pipe from the floor is at least 2 m.

Another important aspect is the maximum length of certified gas hoses. In Russia, it has no restrictions. In Europe it is 2 m. We can have products from 2 to payday loans gallatin tn 10 m and more. It all depends on the tasks of the owners and working conditions.

Transfer aspects

When a gas pipe interferes in the kitchen, it can be moved or disguised. In the first case, you must strictly comply with the regulatory requirements for the transfer of a gas pipe in the kitchen.

Here the same installation criteria are met:

The maximum length of flexible elements is 3 m.

The norms of the gas pipe in the kitchen in height from the floor are 2 m (minimum).

Connection sections must be rigid.

The pipeline itself should be painted.

Sections of the intersection of the system with the walls are “packed” - a special case is used.

When working with a network that transfers gas, block the gas before working.

You need to define your tasks. It is better to designate them schematically and show them to specialists.

And the decision to cut or move the pipe in the kitchen is the prerogative of special services. The owner can only indicate his intention. And the masters can approve or prohibit it. They will tell you what the price of such an update is, where it is better to start with financial assistance grants and who to contact.

The algorithm of actions in solving these problems is as follows:

1. Contacting the gas company at the registration site. Create a statement of desired changes.
2. On the basis of the application, the masters arrive. They examine the conditions, carry out a check and the necessary calculations so as not to violate the norms for the location of the gas pipe in the kitchen.
3. Create a budget. When the finished plan is in the hands of the customer, other formalities are settled, the customer pays for the service. If necessary, the plan is revised.

If the customer's scenario is not safe, or the estimate is not good for him, he can disguise the pipe. For example, purchase a special elegant box

If there are no dilemmas with the estimate, then within 5 days sow its approval, the masters arrive at the customer. Prior to their visit, the client can:

1. Contact them and find out if they need any consumables and immediately resolve this issue,
2. Free up the area for dismantling and old products and installing new ones. Workers should not have problems accessing the network.
3. Protect all valuables, kitchen appliances and surfaces. A tarpaulin or similar material is used for protection. After all, the work ahead is very dusty.
4. The valve is blocked. Gas should not go to the pipes during this period. Attaching components is easier with a siphon connection.

The work itself goes like this:

1. Pipes are purged to remove residual gas and debris (after blocking the gas).
2. The unnecessary component of the system is removed.
3. The resulting hole is plugged.
4. A hole is made at the installation site of the new element.
5. A new structure and other elements are welded here, if they are in the project.
6. The crane is installed. The connecting sections are sealed with tow.
7. The stove is connected. The norm is observed at what distance from the gas pipe you can put the stove. This aspect has already been considered here (the valve is at the level of the connecting fitting, the minimum distance from the side of the plate is 20 cm). With the upper variation of the fixed annuity interest rate wiring, the shut-off valve is placed on the descent to the gas apparatus. Distance from the floor: 150-160 cm. The gas riser is at least 20 cm away from the tap.
8. An act of completed works is formed and signed.

A question of disguise

Is it possible to hide a gas pipe when there is no way to transfer it? It is possible and necessary. Special boxes are available for sale.

You can come up with your own plan on how to hide the gas pipe, and at the same time the counter in the kitchen.

If you have absolutely no idea how to do this effectively and harmoniously, look at the photo “How to hide gas pipes in the kitchen?”

Conclusion

It is necessary to install gas pipes in the apartment and in particular in the kitchen in accordance with current regulations. This is both legality and a guarantee of your safety.

The ends of the reconstructed sections between polyethylene and steel pipes must be sealed.

1. What is the distance of the gas pipe from the intake?

1.1. Dear Vladimir,

Issues with the construction of structures in the protected zone of gas pipelines are quite controversial. The main regulatory act in this area is Decree of the Government of the Russian Federation of November 20, 2000 N 878 (as amended on May 17, 2016) "On Approval of the Rules for the Protection of Gas Distribution Networks".
To start:
"protective zone of the gas distribution network" - a territory with special conditions of use, established along the routes of gas pipelines and around other objects of the gas distribution network in order to ensure normal conditions for its operation and exclude the possibility of its damage (clause "e" clause 3 of the Resolution);
According to p.p. "a" p. 7 of the Resolution,
For gas distribution networks, the following security zones are established: a) along the routes of external gas pipelines - in the form of a territory bounded by conditional lines passing at a distance 2 meters on each side of the pipeline.
I assume that you are talking about a conventional low-pressure gas pipeline, that is, pipes that are often laid along the streets on iron poles.

The types of activities prohibited in the buffer zone are established by paragraph 14 of the Decree, in particular, there is a paragraph. "e", prohibiting:
fence off and block off security zones, prevent the access of personnel of operating organizations to gas distribution networks, maintenance and elimination of damage to gas distribution networks.

The security zone itself must be marked in the land management documents for the site.

In doing so, keep in mind the following:
1. With regard to structures, including fences, it matters what was built earlier: the fence itself or the gas pipeline.
2. Now it is not uncommon for a gas transportation organization (the corresponding Oblgaz) stupidly concludes public easement agreements with land owners, that is, the owner must allow a gas service employee to enter his territory for pipe maintenance. This excludes claims about the fence in the security zone.
3. The law distinguishes between the concept of a security zone and the concept of a minimum distance to an object. If the object is located within the security zone and does not interfere with the operation of the gas pipeline, the courts do not make a decision on the demolition of such objects;
4. Disputes over the possible demolition of structures within the buffer zone are resolved exclusively in court, while, as a rule, land management and () or construction and technical forensic expertise is required. That is, not every fence neighbor / oblgaz will argue.

Based on this, if you need to erect a fence in the protected zone of the gas pipeline, I recommend that you go to the oblgaz and consult - perhaps they will not have claims if an easement agreement is concluded.

2. What is the distance of the gas pipe from the intake in snt.

2.1. Nina Vasilievna, it is impossible to unequivocally answer your question, since there are no data on the type of gas pipeline laying and its pressure in the appeal.
1. If the gas pipeline is underground: According to SNiP 42-01-2002 Gas distribution systems updated version of SP 62.13330.2011 Appendix B, the distance from the gas pipelines to the foundations of buildings and structures with a nominal diameter of up to 300 mm: - up to 0.005 MPa - 2 meters; - St. 0.005 to 0.3 MPa - 4 meters; - St. 0.3 to 0.6 MPa - 7 meters. Over 300 mm: - up to 0.005 MPa - 2 meters; - St. 0.005 to 0.3 MPa - 4 meters; - St. 0.3 to 0.6 MPa - 7 meters. Also, 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, a security zone is established for gas distribution networks along the routes of external gas pipelines - in the form of an area limited by conditional lines passing at a distance of 2 meters from each side of the gas pipeline.
2. If the gas pipeline is above ground: The distance to household buildings is not standardized. It is only necessary to comply with the conditions for crossing the gas pipeline with window and door openings - 0.5 m and below the roof - 0.2 m.

3. At what distance from the gas pipe can you put a barbecue.

3.1. Check with the pipe owner. Gas pipelines may differ in hazard class, respectively, and the zones may be different.
Sincerely.

4. Hello, at what distance from the gas pipe can a house be built?

4.1. To answer your question, you need to have information about the gas pipeline (class, diameter, categories, etc.), but if you have such information, you have the opportunity to independently determine the minimum distance at which there are legal grounds for building a residential building (in order to eliminate the risk of demolition of the house).
Be guided by clause 3.17 of the Decree of the SNIP Gosstroy of the USSR dated 30.03.1985 No. 30, SNiP 2.05.06-85 *.
I also recommend contacting the owner of the specified gas industry facility for clarification on your issue.
Get an extract for the land plot, the specified extract reflects information about the encumbrance, according to the specified cadastral number of the object of encumbrance, get an extract on the right of ownership.

According to Art. 90 of the Land Code of the Russian Federation, the boundaries of the security zones on which the gas supply system facilities are located are determined on the basis of building codes and regulations, the rules for the protection of main pipelines, and other regulatory documents approved in the prescribed manner. On these land plots, during their economic use, it is not allowed to build any buildings, structures, structures within the established minimum distances to the gas supply system facilities.
It is not allowed to interfere with the organization - the owner of the gas supply system or the organization authorized by it in the performance of maintenance and repair of gas supply system facilities, the elimination of the consequences of accidents and disasters that have arisen on them (point 6, article 90 of the Land Code of the Russian Federation).

Good luck to you.

5. At what distance from the gas pipe can you plow the ground.

5.1. The security zone is a piece of land located between two parallel lines running on both sides of the pipeline axis (parallel).

The distance from the axis of the gas pipeline to the border depends on the category of the gas pipeline. The following regulations are currently in effect:
along the routes of external gas pipelines - 2 meters on each side of the gas pipeline;
along the routes of underground gas pipelines made of polyethylene pipes when using copper wire to mark the route of the gas pipeline - in the form of a territory limited by conditional lines passing at a distance of 3 meters from the gas pipeline from the side of the wire and 2 meters from the opposite side;
along the routes of external gas pipelines on permafrost soils, regardless of the material of the pipes - in the form of a territory limited by conditional lines passing at a distance of 10 meters from each side of the gas pipeline;
around separate gas control points - in the form of a territory bounded by a closed line drawn at a distance of 10 meters from the boundaries of these objects. For gas control points attached to buildings, the security zone is not regulated;
along underwater crossings of gas pipelines through navigable and raftable rivers, lakes, reservoirs, channels - in the form of a section of water space from the water surface to the bottom, enclosed between parallel planes spaced 100 m from each side of the gas pipeline;
along the routes of inter-settlement gas pipelines passing through forests and tree and shrub vegetation - in the form of clearings 6 meters wide, 3 meters on each side of the gas pipeline. For above-ground sections of gas pipelines, the distance from trees to the pipeline must be at least the height of the trees during the entire life of the gas pipeline.
Moreover, the standard distances are established taking into account the significance of objects, the conditions for laying a gas pipeline, gas pressure and other factors, but not less than building codes and regulations approved by a specially authorized federal executive body in the field of urban planning and construction. That is, more than the above is possible, but less is impossible. These standards were introduced by Decree of the Government of the Russian Federation of November 20, 2000 No. 878 "On Approval of the Rules for the Protection of Gas Distribution Networks".

As a rule, on private land plots there are only pipes for supplying gas consumers. For example, it can be a steel pipe with a diameter of 80 mm. Such a gas pipeline has a security zone of 2 meters on each side.

My friends, more than 20 years ago, bought a plot where they built a house. Since then, they have paid taxes and made documents for the house, everything is as it should be. Only last year they found out that there is a main high-pressure gas pipe at a distance of 270 meters from the house. And there is a threat of demolition of the house. What can be done in this situation? Read answers (2)

6. At what distance should the power line support of 10 kV be from the main gas pipe.

6.1. GOST 12.1.051-90 Occupational safety standards system (SSBT). Electrical safety. Safety distances in the security zone of power lines with voltage over 1000 V

2. SECURITY ZONES OF POWER LINES

2.1. The security zone along overhead power lines is established as an air space above the ground, limited by parallel vertical planes spaced on both sides of the line at a distance from the outermost wires horizontally, indicated in Table 1.

7. At what distance from the low pressure gas pipe can trees be planted?

7.1. SW. Igor, according to those. norms, the security zone of the low-pressure gas pipeline is 2 meters. Based on this, it is necessary to take into account the possibility of forming a tree crown at a specified distance from the pipe.

8. A neighbor asks for consent to lay a gas pipe (aerial) in my area along the fence. A bathhouse adjoins the fence (about 1 m distance from the fence to the bathhouse). What are the burdens on me?

8.1. The security zone from the aboveground gas pipeline (depending on what kind of pressure) is 2 meters. There may be problems with the demolition of your bath.

9. A neighbor wants to run a gas pipe to his house along my fence, a fence 2 m high, brick posts between them a metal profile fence what are the standards for conducting a gas pipe by air to a private house, what should be the supports for the pipe, at what height, at how far from a neighboring house or plot, is it a violation to lay a gas pipe along the fence.

9.1. Good afternoon!
All these questions should be addressed, first of all, to the gas service.
As for your fence, if it is only YOUR fence, then placing a gas pipe on it is exclusively with your written consent.
Otherwise, the placement of an air gas pipeline to your neighbor's house is possible on the territory of the neighbor's land.

9.2. Hello, a neighbor without your consent has no right to run a pipe along your fence. This is your property and only you have the right to dispose of it as an owner in accordance with Article 209 of the Civil Code of the Russian Federation.

9.3. In accordance with SNiP 42-01-2002 FZ "Technical Regulation" No. 184 of 2002, as well as Government Decree No. 858 - SP 62.13.3310.2011, there should be a distance of 2 to 3 m.

9.4. From 2 to 3 m there should be a distance in accordance with SNiP 42-01-2002 FZ "Technical Regulation" No. 184 of 2002.

9.5. Gas pipe at the site: what restrictions and rules must be observed during gasification
Laying gas pipelines on the site of a private house is a responsible task, since gas is an explosive substance. The installation of the gas pipeline must comply with all building codes and regulations, as well as take into account some of the restrictions that are imposed on these systems for safety purposes. First of all, to understand the issue, it is necessary to understand the types of gas pipelines.
The presence of gas pipes and equipment on the site implies compliance with safety rules during construction.

7 Gas pipe on the site: what are the restrictions for the buffer zone?
Varieties of gas pipelines
Depending on the pressure under which gas moves through the pipes, gas pipelines are classified into three main types:
low pressure lines;
medium pressure lines;
high pressure lines.
Low pressure line. The pressure indicator in such communications reaches 0.05 kgf / cm². Such pressure in gas pipeline structures is typical for economic systems that supply gas to ordinary consumers. Such networks are mounted for residential and administrative buildings, which include: multi-storey residential buildings, educational institutions, offices, hospitals, etc.
Note! For household needs, as a rule, gas is used, which has a high thermal conductivity coefficient (about 10,000 kcal / Nm³).
Pipelines with average pressure indicators. In such pipelines, gas is transported under pressure from 0.05 kgf/cm² to 3.0 kgf/cm². In most cases, such lines are used as trunk lines, and are also mounted in the main city boiler houses.
High pressure pipelines. The pressure indicator in such pipelines can vary from 3.0 kgf / cm² to 6.0 kgf / cm². Such lines are mounted to provide gas to various industrial enterprises.
Gas pipe on the site what are the restrictions
Networks transporting gas to end consumers are low pressure lines
There are situations in which the pressure in the gas pipeline structure may go beyond the established limits. In some cases, it reaches 12.0 kgf / cm² (highest pressure lines). The organization of a system with such pressure indicators requires separate calculations. All gas pipelines are classified not only in terms of pressure, but also depending on the material from which they are made.
Operational features of gas pipelines from different materials
Gas pipeline communications with high pressure are mounted from pipes that have large dimensions. In the case when it is necessary to perform a structure of increased strength, seamless steel pipes are used. Docking of such pipes is carried out using welding equipment. Welding such products is a rather laborious process.
The most suitable material for pipes through which gas will be transported is copper. This is due to the fact that copper has several operational advantages over steel counterparts. The main advantages of pipelines from this material:
small mass;
simple installation;
corrosion resistance.
However, copper gas pipelines are used quite rarely, as they are very expensive.
If pipes with thin walls are used when laying gas transmission communications, it is recommended to take into account their high coefficient of thermal conductivity. Due to the high thermal conductivity, such products tend to be covered with condensate.
Helpful information! To ensure anti-corrosion properties, it is recommended to cover the surface of steel pipelines with oil paint (in several layers).
Gas pipe on the site what are the restrictions
When laying underground gas networks, the use of polymer pipes is allowed
When laying gas transmission lines underground, as a rule, pipes made of modern polymeric materials are used. The most popular polymers used for this purpose are polypropylene (PP) and polyethylene (PE). The main advantages of such polymers:
high coefficient of flexibility;
resistance to corrosion;
ease of laying;
democratic value.
Pipes made of polymer materials are ideal for underground installation, as they feel comfortable under such conditions. It is very important to remember that plastic pipelines are used only for organizing lines with low pressure indicators. Polymer pipes have the appropriate marking, which determines their operational affiliation. For example, polyethylene pipes used for gasification of private buildings are produced in black and have a yellow marking.
The layout of the gas transmission structure inside the house is carried out using special flexible hoses. Such hoses are made from a special material - vulcanized rubber, they also differ in that they have reinforcement. In most cases, they are used for joining gas stoves to gas water heaters.
Such hoses have operational limitations that you should pay attention to:
they do not apply if the room temperature exceeds +45 °C;
it is forbidden to use rubber hoses in areas that are located in seismically active areas (more than 6 points);
they are not used in communications characterized by high pressure.
Options for laying gas pipeline systems
To date, there are three main options for the installation of gas pipeline structures:
underground (closed);
elevated (open);
interior.
Gas pipe on the site what are the restrictions
The depth of the gas pipe at the site depends on the type of gas that will be transported through it
Closed way. This method of laying gas pipeline communications is the most common today. The depth of laying the pipe depends on the moisture content of the gas. If wet gas moves through the pipe, then it is laid below the freezing level of the soil. A pipe with dry gas is mounted from 80 cm below ground level. All necessary restrictions, including the distance to a residential building, are described in the relevant regulatory documentation (SNiP 42-01-2002). In a closed way, pipes made of steel or polyethylene can be installed.
Helpful information! Gas pipelines in suburban areas in most cases are laid in an open way. This is due to the fact that this method is considered the most appropriate, from an economic point of view.
Open way. As a rule, this method of laying gas transmission communications is used if it is impossible to mount the system underground due to the presence of natural or artificial barriers. Such barriers include:
reservoirs;
ravines;
various buildings;
other communications.
For laying in an open way, only those pipes that have high strength are allowed to be used. This description includes steel products, which are the main structural elements of such systems. The distance of an open steel gas pipeline to a residential building is not established.
Internal way. This method of laying gas pipeline systems implies their location indoors. In this case, the distance to the walls and to other objects inside the room is determined depending on the specific case. When laying internal gas pipelines, their installation inside the walls is prohibited. For the arrangement of internal gas structures, pipes made of steel and copper are used.
Gas pipe on the site what are the restrictions
For open installation, only metal pipes are used.
Rules for gasification of a private house
First of all, before starting the installation of a gas pipeline in a private area, it is necessary to inform the local gas service. As a rule, together with the gas service, the order of future work is determined. In addition, it is necessary to obtain permission to carry out future work from another inspection - the automobile one. Next, you need to draw up a plan for gasification of the site. To do this, it is recommended to contact specialists, since self-planning can lead to an emergency.
If there are already houses connected to the gas pipeline in your area, then the work is simplified. In such a situation, all that needs to be done is to connect to the main highway passing nearby. However, before connecting, it is definitely recommended to contact the gas service, which must necessarily provide you with the working pressure parameters in the main line. These data are necessary to select the material of the pipes from which the future structure will be mounted.
All systems transporting gas to consumers are divided into two main types:
autonomous;
central.
Consider step by step the steps that need to be performed directly when laying gas pipeline communications in a private house:
Lay the gas pipe from the distributor to the house. If necessary, a pipe is inserted into the main line.
At the point of entry of the gas pipe into the house, it is necessary to install a special cabinet. Such a cabinet must necessarily be equipped with a device that lowers the pressure (reducer).
At the next stage, intra-house wiring is performed. To organize a gas pipeline inside the house, it is recommended to use pipes that can withstand low pressure.
Next, the mounted system is checked for operability. All necessary commissioning works are being carried out.
Gas pipe on the site what are the restrictions
A special box is installed at the inlet of pipes to the house, in which a pressure reducer is located, and a gas meter can also be installed in it.
Important! The inspection of a new gas pipeline is carried out in the presence of a gas service inspector.
SNiP restrictions when laying a gas pipeline
As mentioned above, SNiP 42-01-2002 describes all the necessary restrictions on the installation of gas pipeline structures. The distance between the residential building to the communication is determined by the gas pressure: the higher this indicator in the pipe, the farther it must be located from the house.
Consider the main provisions that are described in SNiP:





The points prescribed by building codes and regulations must be complied with without fail, as they take into account fire safety and plumbing standards.
Gas pipeline security zone
The security zone of gas pipeline communication is the space that is located between the pipe and two imaginary lines located in parallel on the sides of it. The distance from the axis of the pipeline to these lines may be different, since it depends on the pressure indicator inside the communication.
Gas pipe on the site what are the restrictions
The security zone for areas with low pressure is at least 2 meters in each direction from the pipe
Consider examples of security zones for various gas pipelines:
for communications that are laid in an open way, the security zone will be 2 m on each side of the pipe;
for lines that consist of polyethylene pipes with special copper wires marking the route, it is 3 m from the communication (from the side of the wire) and 2 m from the other side;
along the gas transmission lines, which are laid in the conditions of permafrost, the security zone is 10 m on each side of the communication. This indicator remains the same regardless of what material the track is made of;
for points that regulate gas in the pipeline, a conditional, closed line of the buffer zone is 10 m from their borders. For private gas control points, the security zone is not regulated;
the security zone for gas pipelines laid under water is 100 m;
for communications laid in forest belts and in areas with tree and shrub vegetation, the security zone is 3 m (in the case of underground laying of the route). And for communications mounted above the ground, the distance from the tree to the pipe must be no less than the height of this tree;
for private purposes, as a rule, pipes are used, the cross-sectional index of which is at least 80 mm. For such a pipeline, the security zone will be 2 m on each side.
Gas pipe on the site: what are the restrictions for the buffer zone?
Certain restrictions are imposed on the territory that is located within the buffer zone. Consider them:
the construction of various buildings is strictly prohibited;
if a part of the bridge falls within the protected zone of gas transmission communication, then its demolition or work on its reconstruction is prohibited without obtaining permission from the relevant authorities;
Important! It is strictly forbidden to destroy fiducial and other signs located on the communication line.
It is forbidden to arrange landfills in the protected zone;
it is forbidden to store toxic waste, acids, alkalis or other aggressive chemical compounds within the security zone;
it is forbidden to erect blocking elements within the security zone (for example, fences);
on the territory that is within such a zone, in no case should a fire be made;
it is forbidden to cultivate the soil at a depth that exceeds 30 cm.
For gas pipeline structures that are in the process of being laid, the approval of such zones is carried out in the presence of the owner of the site. For existing gas transmission lines, the presence of the owner of the land plot is not mandatory.

9.6. Dear Svetlana, Krasnodar!
Article 274 of the Civil Code of the Russian Federation The right to limited use of another's land plot (servitude)
Part 1. The owner of real estate (a land plot, other real estate) has the right to demand from the owner of a neighboring land plot, and, if necessary, from the owner of another land plot (neighboring plot), the right to limited use of the neighboring plot (servitude).
An easement may be established to ensure passage and passage through a land plot, laying and operating power lines, communications and pipelines, providing water supply and melioration, as well as other needs of the owner of immovable property that cannot be provided without the establishment of an easement.

Based on the above:
- only after the establishment of the Easement (paid) by the Court, this gas pipe can be laid along your fence.

Good luck Vladimir Nikolaevich
Ufa 30.08.2019

9.7. Firstly, if the fence is yours and built with your money, then the neighbor cannot block his gas without your consent, "Civil Code of the Russian Federation (Part One)" dated 11/30/1994 N 51-FZ (as amended on 07/18/2019)
Civil Code of the Russian Federation Article 209. Content of the right of ownership

1. The owner has the rights to own, use and dispose of his property., secondly, this action is contrary to the requirements of SNiP 42-01-2002 FZ "Technical Regulation" No. 184 of 2002, as well as Government Decree No. 858 - SP 62.13.3310.2011, as they provide a distance from the boundary of 3 meters. If he holds without your consent, you can oblige him through the court to remove everything back.
Good luck!

9.8. Your fence is your property. Only you have the right to dispose of this property (Article 209 of the Civil Code of the Russian Federation).
And for the construction of the gas pipeline there is a land plot, which is to be determined by the building organization.

9.9. To run a gas pipe along your fence, a neighbor must take permission from you, this is expressly stated in clause 7 p.p.e)
Decree of the Government of the Russian Federation of December 30, 2013 N 1314 (as amended on February 21, 2019) "On approval of the Rules for connection (technological connection) of capital construction facilities to gas distribution networks
f) the consent of the main subscriber to connect (technological connection) to the gas distribution and (or) gas consumption networks of the main subscriber, as well as the construction of a gas pipeline on the land plot of the main subscriber, if the connection is carried out on the land plot, the owner of which is the main subscriber, in the cases provided for in clause 34 of these Rules

The issue of issuing a technological opportunity to connect to a private house to a neighbor is decided by the gas distribution organization.

9.10. SNiP 42-01-2002 describes all the necessary restrictions on the installation of gas pipeline structures. The distance between the residential building to the communication is determined by the gas pressure: the higher this indicator in the pipe, the farther it must be located from the house.

The main provisions that are described in SNiP:

The distance between the foundation of the residential building and the low pressure gas transmission line is 2 meters;
the distance between the foundation of a private house and a pipe with medium pressure is 4 meters;
high pressure gas pipelines should be located at a distance of 7 meters from a residential building;
in accordance with SNiP, the distance of the pipeline that transports gas to a window or doorway must be at least 50 cm;
the distance from the pipe to the roof of the house must be at least 20 cm.
The points prescribed by building codes and regulations must be complied with without fail, as they take into account fire safety and plumbing standards.

9.11. I would not coordinate the pipe along the fence, let leads in his own area, but he needs a pipe. There is a security zone for the gas pipeline, nothing can be built, etc.

Standards for buffer zones are regulated by SP SP 62.13330.2011* (former SNiP 42-01-2002) in force on the territory of all regions of the Russian Federation. Gas pipeline routes and other objects of the gas distribution network must be operated in strict safety conditions, excluding the possibility of damage, and exclude access of third parties to the location of the gas pipeline, shutoff valves and gas equipment. Even minor damage to the insulation of steel pipes provokes corrosion of the metal and can lead to.

10. Please, is it a violation that my drain pit, a household building, a wooden outdoor toilet, is located at a distance from the low pressure gas pipe. Thanks in advance.

10.1. Distance not specified. But - it is not a violation in any case, if it was legally established before the laying of the gas pipeline.

11. Are there any norms for the distance from the gas pipe to the fence, so that you can apply for servitude with the gas company.

11.1. The gas pipe does not pass through the territory of your land plot, therefore it is impossible to establish an easement here, because the gas company does not use your land. plot.

12. The gas pipe runs along the edge of the private area, at a distance of 1 m from the boundary. Tell me, can a professional sheet + brick fence be placed on this boundary? Or what should be the indent?
And on the other hand, how much should you retreat when planting trees and shrubs?

12.1. It depends on which gas pipeline runs underground. Most likely the security zone will be 5 meters from the axis in each direction.

13. Do I need the neighbor's consent when I lay an underground gas pipe along his site from the side of the street at a distance of 2 m from his fence? He is afraid for his lawn.

13.1. Good afternoon Vlad. You don't need your neighbor's consent.
