The device gas communications in the apartment is subject to certain requirements, therefore, independent installation and connection of equipment, as well as the transfer of the gas pipe to another place categorically is prohibited.
All questions on the laying of domestic and external gas pipelines are solved by the gas service, without the permission of which one can only move the stove a limited distance.
We will tell you how to obtain approval for the replacement of the pipeline, as well as describe the transfer technology of the inter-apartment main. The proposed instructions are not a guide to action, all work must be carried out by a gas service representative.

The reasons for the transfer of gas pipes in the kitchen
All work on the transfer and replacement of metal pipes, especially those requiring welding, is carried out by representatives of Gorgaz or another authorized organization. Having received an application from tenants, they are always interested in the reasons for the planned changes.
Most often it is necessary to change the pipe wiring in the kitchen without changing the layout and transferring the equipment to other rooms.
The reasons may be different:
- replacing old equipment — buying a gas heater, stove or boiler — for which a little more space is needed;
- overhaul in the kitchen;
- the transfer of the gas stove from the window at 0.5-2 m in the direction of the sink;
- change of place gas meter installation;
- the transfer of a horizontal pipe from a large height under the tabletop, etc.
Often the transfer of pipes is required in new buildings, where the initial location of significant kitchen objects defies logic and explanation: suppose if in a 15-meter kitchen a gas stove is near the window, the sink is in the opposite corner, and the hood is on the other side above the entrance in the kitchen.
We have to correct the mistakes of designers, move the stove closer to the sink, so that the cooking takes place in a comfortable environment.
It is strictly forbidden to carry out work on the transfer of gas risers. The only change allowed is masking of pipes with easily dismantled structures, for example, hinged kitchen cabinets.
The most common reason is the purchase of a new kitchen unit with built-in equipment (oven and hob). In this case, the pipe is required to either shorten or lengthen - depending on the planned installation location of devices.
If you want to know how best to move the gas pipe in the apartment with redevelopment, we recommend contacting the project organization to draw up a transfer scheme.
The fact is that in typical urban apartments reinstall the risers, pipes, as well as any gas equipment in living rooms is prohibited, and even to combine the kitchen and room is also required resolution.
Getting approval for the replacement of the pipeline
Whether or not a transfer is possible, only authorized bodies can decide, that is, the gas service of your city (district). Any dismantling and installation work is allowed to be done only by a qualified specialist. Of course, without approval, the transfer of pipes cannot be carried out.
Even such a simple step, like trimming a pipe by 10 cm, needs to be coordinated, since all work related to the gas pipeline is in the category of risk-related
Permission is issued in the following sequence:
- Find out the contact details of the gas service at the place of registration, contact the experts, explain the situation, consult.
- You make an application (in a standard form) that will “launch” the approval process.
- Based on the application, a representative of the gas service arrives at your home. Time is specified in advance.
- The specialist makes an inspection, listens to wishes, answers questions. Often at this stage you have to change plans, because the desired transfer does not meet the requirements safety (a preliminary study of the rules of installation of the pipeline will save this unpleasant moment).
- Approval of the final transfer scheme, budgeting. All documents are issued by the organization providing the services. Without the consent of the owner of the housing work is not made.
- If the transfer conditions are met, pay for the service on the receipt and agree on the start time of the work.
The approval procedure usually takes several days; it can take only a long time for one reason: if property owners and gas service representatives did not find a compromise solutions.
Any factors that violate the rules gas stove installations (boilers, meters, columns), can cause failure in the transfer of pipes.
General requirements and regulations
In order for the approval process to proceed smoothly, it is better to get acquainted in advance with the main provisions of the gas system in residential premises. As a cheat sheet, you can use the regulatory document - SNiP 2.04.08-87 * (current version).
The room must have a natural forced-air and exhaust ventilation, that is, there must be a window with opening air vents / transoms and a ventilation duct with a good draft.
If the walls and the ceiling consist of flammable materials (wood), they must be plastered or covered with metal sheets.
Gas pipes are used to transport fuel to consumers - stoves, ovens, columns, so the location of the equipment is important, no less than the wiring of pipes.

The height of the ceilings in the room where the gas stove is installed should not be less than 2 m 20 cm. If it is an attic or an extension with a sloped ceiling, choose a place that is suitable for regulatory parameters
The distance from the plate to objects located through the passage (for example, to the table) must be at least 1 meter. It promotes free movement around the kitchen.
The element of valves and fittings - a valve to turn off the gas supply - must be located at a distance of 0.2 m from the plate (can be installed on a pipe hidden under the table top, at a height of 0.75-0.80 m)
The room in which the gas stove or column is installed must be separated from the next room / corridor by a door. It is forbidden to leave the doorway to the living room open
The gas stove must be at least 0.07 m away from the wall covered with non-combustible material. If the equipment is installed in a corner, the rule applies to both walls.
To connect a gas pipe and a household appliance, flexible hoses (rubber-fabric hoses, bellows hoses) are allowed.
To connect the consumer (oven, stove) and the pipeline used fitting. The eyeliner is carried out at the height of its location.
Pipes for internal wiring should be manufactured in accordance with GOST 380-88 (for products of ordinary quality) or GOST 1050-88 (for products of quality steel)

You also need to know that the shut-off valve from the pipe can not be cut. This is a mandatory element of the gas system. Moreover, when you change the location and gas valve replacement, it is necessary to make sure that it is in direct accessibility.
If it is located under the table top, access should be made through the cabinet door (without the back wall) or through the opening fragment of the table top.
The order of the transfer or replacement
It is not recommended to change anything yourself, even a flexible eyeliner. The cutting, extension or transfer of pipes should be done by a representative of the gas service. However, knowing the sequence and some nuances of action when working with pipes will not interfere with the owner of the property.
# 1: Preparing to work with pipes
Usually a team of workers (usually 2 people) comes within the next week after agreement. At this point, it is already known which areas will be dismantled or lengthened, whether additional equipment will be installed, for example, gas water heater. Consider what else it is worth contemplating.
Taking this opportunity, you can install a gas meter or completely change outdated equipment. If additional installation is planned, workers must be informed in advance.
All equipment used in the kitchen belongs to the owner of the apartment and is purchased at his expense, therefore, it is better to immediately ask what else you need to buy to transfer appliances and work with pipes.
If we are talking about connecting the stove or oven, you have to buy a bellows hose of a certain length. Metal pipes assemblers bring with them, their cost is included in the total amount of payment for services.
So that there were no hitches, and the work was done quickly, you need to free up space from unnecessary furniture or other items. Everything that cannot be taken out, needs to be covered with dense nonflammable material.
# 2: Dismantle old construction
Most likely, when transferring the pipe, it will be necessary to cut off a piece of the old one and build up a new one, but in a different direction. To this end, the master, using a special tool, removes unnecessary pipe sections.
Of great importance is the qualification of the master admitted to the transfer of pipes. Fitters and electric welders undergo special training and certification, after which they receive an appropriate certificate.
When dismantling the cuttings leading from the riser to the consumer, it is necessary to leave a small area on which the gas valve is mounted. This horizontal piece of pipe can neither be removed nor replaced. The only exception is pipeline damage requiring full replacement.
Sometimes residents of the upper floors require that a large fragment of a pipe be removed, rising 1.8 m from the floor to the ceiling, and then bent down 180 °. Trim the pipe and install on the left section of the crane is strictly prohibited. The only way out is to digest the pipe so that the crane can be installed under the table top, to a height of 0.75 m.
# 3: Gas wiring options
The transfer of pipes always takes place according to the same scheme: they are moved parallel to the ceiling or walls, since the diagonal and any curve placement is prohibited. Consequently, most often, the layers from the riser are lowered down, under the tabletop (less often raised), or the vertical fragment is transferred to the right / left.
A popular variant of masking gas equipment: a tap, to which easy access is provided, is mounted on a pipe passing below the worktop. Bellows hose stretched from the crane to the device
When changing the direction of the pipes, it is necessary to remember the following rules:
- internal gas wiring is an open system, all covering elements are camouflage in nature and should not be firmly fixed;
- through the ventilation channels, as well as doors and windows to lay the pipeline is prohibited;
- metal structures are predominantly used; flexible liner allowed on equipment connection sites, but their length should not exceed 3 m;
- a rigid method of connecting pipes and hoses with pipes is used;
- transitions of pipes through walls / partitions equip with special adapters - sleeves.
Any work associated with the transfer of pipes should begin with gas overlap. It is the responsibility of the service provider.
# 4: Welding metal pipes
According to the norms of SNiP, any changes in the position of the pipes must occur by welding. Split connections of two pieces are prohibited.
Threaded connections are used only for installation of gas meters, household equipment and valves.
In the process of welding, the worker should use only serviceable tools and use protective equipment: working clothes made of dense material, goggles (mask), gloves
Places annealed by welding, have an unpresentable appearance, besides they require protection against corrosion. After completing the work, they must be treated with waterproof paint for metal, matched to the color of the walls.
# 5: Using bellows hoses
Before building or moving a gas pipe, you need to consider the option mounting flexible transition. It is carried out using bellows hose.
When choosing a flexible liner, pay attention to its type. It is listed in the technical specifications and has the designation "union-nut", "nut-nut", "union-union"
Previously used rubber and rubber products, but the bellows was stronger than outdated materials. At its core, it is a metal or composite corrugation, but having unique qualities.
For a long time, it maintains tightness and elasticity, even with active mechanical action. The shell structure is maintained even with a strong pressure of the transported medium or with constant mechanical stress.
Installation of bellows connectors is also made by a gas service worker. It performs the connection of boilers, columns, stoves and ovens according to all the rules of EIR and, if necessary, uses adapters and seals, for example, FUM tape.
Gas pipes in the kitchen are trying to hide behind decorative panels or furniture. Pipe masking options are described in this article.
Conclusions and useful video on the topic
With the appearance of long flexible connections, the transfer of the internal gas pipeline has become less relevant, but in some cases it is still necessary to contact the gas service. The most common reasons for appeals - in the presented video.

Finally - on the consequences of the illegal transfer of gas pipes. If you yourself plan to cut a piece of a gas pipe or connect household equipment, you should be aware of the administrative and criminal penalties.
The minimum fine for unauthorized work - 2 thousand. rubles, and if a person suffers as a result of improper work, then up to 5 years of imprisonment may be incurred.
