Gas connection to a private house. Gasification of the house: input, wiring, location of gas consumers Input of gas into a private house norms

The most important factor when choosing a gas pipeline system in private property is the presence of a gas main in the settlement or in its immediate vicinity. Without it, gasification will have to be based on autonomous design solutions.

Professional services in the field of gasification of private households

The process of connecting a private house to the gas main involves many legal and technical nuances. Among them:

legal registration of the land plot;
registration of rights to a building;
preparation of a whole package of documents to obtain the appropriate permits for the installation of equipment;
preparation of the project and installation of gas in a private house;
permission to connect to the main pipe, many other technical and legal issues.

The Obedinenie-Gaz company provides homeowners in Moscow and the Moscow region with all services related to gasification of facilities. As a long-time and permanent partner of FSUE MOSOBLGAZ, one of the largest gas distribution companies in Russia, we quickly and successfully solve problems of any degree of complexity.

When all preconditions are met and the necessary documents are ready, it is time to develop the project and design documentation. Then installation work is carried out in accordance with the decisions made on the construction of the internal network and the permits obtained for the installation of gas equipment in the house and connection to the gas main.

Within the framework of each project and at the request of the customer, we provide a full range of services related to the installation of a gas pipeline in a private house, providing prices and price lists for them in accordance with the individual terms of the contract and a pre-calculated estimate.

Local gas pipeline and connections of a private house to the main line

Local gas pipelines are built in the absence of main gas pipelines in the immediate vicinity and always taking into account the characteristics of the facility, the requirements of the owner and safety levels. Gas boilers are installed and an agreement is signed for the supply of natural gas in containers of the required volume.

Of course, centralized gas supply is more convenient and simpler. This is also more reliable, since suppliers who provide fuel to private boiler houses do not always approach their task responsibly. You will have to look for a reliable organization.
Installation of a gas pipe to a private house if there is a main line is carried out in two ways:

aboveground;
underground.

In the first case, the pipe through which gas is supplied to the building is placed on special brackets or supports, leaving it in the open air. This method is not very expensive, but requires constant monitoring and maintenance of the highway in order to protect it from the effects of weather conditions and precipitation.

The underground method is 20-25% more expensive than the previous one. Since the gas pipeline is laid in trenches dug in the ground, it is safer, no maintenance is required, and the area looks much more attractive.

Requirements for the materials used and installation of the gas network in a private building

Installation of gas in a private home and reliable operation of the gas network is impossible without compliance with a number of conditions and standards. We guarantee this 100%.

All materials used in the construction process, regardless of their further purpose (pipes, valves, electrodes), are of high quality, confirmed by relevant documents.
Our craftsmen place dismountable joints in open areas to ensure easy access. This makes it possible to assess the condition of the connection at any time and carry out repairs if necessary.
It is strictly forbidden to embed pipes and other components of the gas network into walls, foundations of buildings. In certain cases, permission is given to lay a pipe in a channel specially made in the wall, but only after approval of the project.
It is also prohibited to attach the gas pipeline to window and door frames, transoms and trim, or plywood partitions.
It is strictly unacceptable to have distortions when laying local pipelines for supplying gas to premises and territory.
For horizontal areas, an inclination towards the equipment is allowed within 0.002-0.005 meters, and in vertical areas any inclination is excluded.
A slope of 2mm/1 meter is allowed only on a riser located on a staircase or in a kitchen space.
Our craftsmen install the taps by positioning the axis of the plug parallel to the wall, on which the thrust nut cannot be located.

A very important safety factor is maintaining the required distances.

The minimum distance from the pipe to the floor can be 2.2 meters, and from 10 cm to the ceiling.
The distance between the wall and the pipe is usually specified in the design documentation.
Its minimum value is equal to the radius of the pipe, and the maximum is 10 cm.

For the construction of a local gas pipeline, we use pipes made of low-carbon or low-alloy steel with a diameter of 150 mm and a wall thickness of 5 mm. We use both welded and seamless products, which are connected to each other only by gas welding using high-quality electrodes.

We recommend installing not only the main gas meter, but also a control gas meter when connecting to the main line, and at least one meter for autonomous gasification. During operation, you can not only monitor actual gas consumption, but also look for options for saving fuel.

Peculiarities of pricing when installing gas equipment in a private home

Like any other company working in the field of gasification of private facilities, Obedinenie-gaz has a certain price list, with the help of which the cost of the entire range of work carried out is calculated in advance. As a rule, the financial component of these works is unchanged throughout Moscow and the region, but a number of parameters influence the overall estimate.

Discuss upfront costs with our consultants by phone or online.
Call a specialist to the site to more accurately and accurately correlate your requirements with the upcoming costs.
Also take into account the technician’s recommendations regarding the safety of equipment operation and permissible loads for the selected configuration.

To obtain favorable terms of cooperation with the Obedinenie-Gaz company, we suggest considering the option of comprehensive services. In this case, we will provide discounts on the total cost of all services included in the turnkey package. We also provide individual types of services if our clients do not require the whole range of services in one place.

Please note that the total price of installing gas equipment in a private home largely depends not only on our starting tariffs and the complexity of the project, but also on the materials and equipment used by the company’s specialists. We discuss them and always try to find the most cost-effective solutions without compromising the quality of the result obtained, taking into account operational safety, reliability of all components of the gasification system of the building, and compliance with the loads.

Gas is the most popular fuel for heating systems. Gas heating is much cheaper than electric heating, and at the same time brings much less hassle than solid fuel counterparts.

However, the process of supplying explosive fuel to a private home requires compliance with a large number of rules associated with both paperwork and significant financial costs.

Laying gas pipelines is a long process and also quite expensive. In order to reduce the cost of the entire process, some installation work can be carried out independently. But for this you need to carefully study the rules and regulations of SNiP.

Procedure for gasification at home

Everyone knows about the flammability, explosiveness, and chemical activity of natural gas, so amateur activity in this situation is out of the question. Gas supply system must be installed exclusively by specialists according to the approved plan.

If you decide to supply gas to your home, prepare for a long paperwork process and be prepared for trips to various authorities with long queues.

Before a team comes to you to carry out installation work, you will have to make a gasification plan, obtain all permits, and only then purchase the necessary gas equipment.

Collection of necessary documents

Before contacting a design organization to create a gasification project for a building, you will have to collect a whole package of necessary documents. Let us note right away that some of the required papers will cost money, so immediately prepare for the financial costs.

So, what papers do you have to collect:

a document confirming ownership of the house and land;
copies of identification documents of the owner;
conclusion on the technical feasibility of carrying out work on gasification of the building;
technical passport from BTI;
a topographic map made to a certain scale, which shows all buildings subject to gasification;
a map showing all laid communications and the planned gas pipeline, which is certified by the gas service;
if the gas pipeline to the house has to be pulled through neighboring areas, written permission from their owners will be required to carry out the relevant work.

This is an approximate list of documents that you will need to collect.

Depending on certain features, for example, underground or above-ground gasification is planned, it may be necessary to provide some more paperwork.

Preparation of project documentation and conclusion of contracts

Please note that services for the preparation of project documentation are paid. This work can only be carried out by design bureaus that have the appropriate license.

There is no point in trying to create a project on your own, since it must take into account a large number of nuances known only to specialists:

depth of the central gas pipeline;
location and depth of gas pipes from the central gas pipeline to the house;
gasification methods (underground or aboveground). This is influenced by the characteristics of the soil, the depth of groundwater, the interweaving of other communications, buildings, road surfaces, etc.;
details of installation work;
connection points for gas appliances and requirements for them in accordance with SNiP;
materials, joints, as well as the distribution of gas pipes inside the house.

In addition, all project documentation must be certified by the relevant organization.

The cost of the project will depend on the complexity of the project itself, the materials used and the design organization itself. Therefore, it makes sense to consider all possible options, study prices, reviews, and then choose the most suitable agency.

To carry out installation work and put into operation the gas supply system, you also need to conclude the following agreements:

Agreement for installation work and preparation of technical documentation.
Agreement on gasification and installation of gas equipment.
The act of putting the gas pipeline and gas equipment into operation.
Inspection report for smoke ventilation ducts.
Agreement for the supply and payment of natural gas.

Selecting a contractor and starting installation work

When it comes to gasification of a building, the choice of contractor must be taken with full responsibility. Before concluding an agreement, make sure that the company has the appropriate licenses, contracts, necessary permits, and qualified employees with all the necessary clearances. Installation work to install an underground or above-ground gas pipeline to the building begins after all documentation has been prepared.

However, it is the contractor who will have to provide reports on the work performed and acts that will detail all the actions carried out on the site. Based on these acts, the gas service will have to connect the gas, carry out a series of commissioning works, and then give you a lecture on safety precautions.

Features of materials and gas supply works

When it comes to gas, in no case should you neglect the rules of SNiP for the selection of materials, equipment and features of installation work, since gas is not only explosive, but also toxic.

All materials that will be used in the process of supplying gas to the house and wiring inside the building, from pipes to electrodes, must be of high quality and have appropriate certificates.

For gasification, low-alloy metal or polyethylene pipes can be used. It is worth noting that polypropylene pipes have a number of advantages compared to metal ones: mother weight, ease of installation, ease of transportation, non-corrosion, electrical non-conductivity, reasonable cost, long service life.

There are a number of restrictions for laying plastic pipes:

above-ground gasification cannot be carried out using plastic pipes;
the use of polypropylene pipes for indoor wiring is prohibited;
use is prohibited in regions where temperatures drop below -45 degrees;
prohibited for use on seismically active soils;
Do not use a plastic pipe to pass through natural or artificial barriers.

It is not allowed to embed any welded or gas pipelines into walls or foundations. They must be located so that they are constantly accessible for inspection, maintenance and repair work.
Elements of the gas pipeline should not come into contact with flammable elements of the building - door frames, window frames, temporary partitions, etc.
Distortions of the gas pipe are not allowed either outside or inside the building. Vertical sections should run strictly vertically, horizontal sections should be laid with a slope of 2-5 mm per meter towards the devices.
The gas riser can have a slope of no more than 2 mm. The riser is located in non-residential premises (change houses) or along the facade of the building. Under no circumstances should he be in places where people usually are (bedroom, dining room, bathroom).
Particular attention should be paid to taps. They should be positioned so that the axis of the plug runs parallel to the wall.

Methods for laying a gas pipeline

The gas pipe from the central main to the facade of the building can pass underground or above its surface. Based on this, underground and aboveground gasification methods are distinguished. It is worth noting that there is often a need to combine these two methods.

So, for example, if a gas pipe has to be pulled across the road, Most often they resort to the above-ground method, so as not to block traffic for a long time. After passing the road, the pipe is deepened underground. However, if new horizontal drilling technologies are used, this need may disappear.

Overhead gas pipeline

An aboveground gas pipeline is much cheaper than an underground one. Savings, in some cases, can be up to 60%. If the gas pipe to the house goes above ground, we will not worry about the depth of groundwater, the intertwining of other communications, or other problems associated with underground work.

However, in this case, pipes laid on must be protected as much as possible from corrosion, deformation, temperature changes and mechanical influences.

In addition, you will have to constantly ensure that unscrupulous neighbors do not connect to your gas pipeline, which, in the case of an underground gas pipeline, is hampered by the depth of the pipe.

Stages of connecting gas to a house (video)

Underground gas pipeline

Although this technology is much more expensive, it is much more popular. When stopping at an underground gas pipeline, you need to remember that the depth of the pipe should be completely comply with the gasification plan for security.

Before the advent of horizontal directional drilling technology, laying gas pipelines underground was associated with a number of problems:

depth of groundwater;
seismically active soils;
passing obstacles and road surfaces;
soil with a high content of corrosive substances.

However, this technology solved all the problems at once, also reducing the time required to complete the work. Instead of the lengthy process of digging a trench, the depth of which can reach 1.5 - 2 meters, a horizontal hole is drilled from the central highway to the building.

It is only necessary to dig two wells near the pipe, to connect to it, and near the building, to enter the house. The inlet and outlet of the drill are spilled with solution and. In the case of difficult soils, the pipe can be laid in a special protective case.

And includes the following works and topics for study:

Gas pipeline pressure;
Materials for gas pipeline;
Connection of gas pipeline pipes in the house;
Requirements for equipment operating on gas (stove, gas boiler);
How to install a gas pipeline and gas equipment in a house;
Delivery and acceptance of a gas pipeline at home.

Let's start with gas pressure and ways to reduce it.

Home gas line pressure

The nominal gas pressure for a home gas pipeline should be in the range of up to 2 mPa ÷ 1000 (artificial gas) – up to 3 mPa ÷ 1000 (natural gas) – up to 4 mPa ÷ 1000 (liquefied gas). Main gas pipelines can have a pressure of 0.1-0.6 MP. The gas pressure is reduced before it is supplied to the internal gas pipeline of the house using a house gas control point (DRP).

The DRP is mounted on the wall of the house in a cabinet or on the site in a cabinet raised on a fireproof platform, with a separate grounding.

Material for internal gas pipeline

The following steel pipes are used for the internal gas pipeline of a house:

Pipes without seams;
Pipe with a straight weld, with an equally strong seam to the main pipe;
With spiral seam;
All types of water and gas pipes.

How to connect gas pipes

Preferably a welded connection of pipes for gas. Connection points for gas fittings can be connected with flanges and threads. The threads are sealed with flax, which is coated with red lead paint or lead white paint. A more modern seal is FUM tape (fluoroplastic sealing material).

When laying an internal gas pipeline, you will have to bend it. Bend radii are standard. When installing pipes up to Ø4 cm, the bending radius must be at least 2.5 times the pipe diameter. For pipes 4-5 cm, the bending radius is at least 3 times the diameter. Pipes of other diameters do not bend in the gas pipeline.

Flange connection of gas pipeline pipes

You can see the flange connection of the pipes in the photo. This connection requires gaskets. They are made from paronite. A flange connection is unlikely to be needed in the internal gas pipeline of a house, although it is possible in a DRP.

Connecting gas pipes by welding

The main connection of gas pipes in the house is welding. Any welding can be used:

class="eliadunit">

Electric arc welding by hand (electrodes No. 42, 42A, 46, 46A, 50A).
Automatic welding with fluxes and wire Sv-08-A, Sv-08-GA.

The same wire is used in gas welding. In the internal gas pipeline of the house, you need to use fittings (valves, valves, taps) only designed for operation in a gas environment.

Requirements for gas-powered equipment

The house is equipped with gas stoves with 2-4 burners in accordance with the relevant GOST or TU.
Gas meters are used to monitor gas consumption.
The water heater must have an automatic system to turn off the burners when the gas “loses”;
Air heating devices operating on gas should have similar automation.

Preparation for installation work

Before installing the systems, you need to complete the following preparatory work:

Make passage holes for pipes (walls, floors, foundations) for laying gas pipeline pipes;
If you plan to hide a gas pipeline, you need to prepare grooves for it;
The floors where gas equipment will be placed must be ready;
When installing equipment on the wall, the walls are plastered;
Plumbing and equipment to which gas and hot water will be supplied must remain in place.

Installation rules

Gas pipes are connected by welding;

Control, shutdown, and regulating devices are connected with threads or flanges. Distortions in connections are unacceptable;
Pipe joints cannot be hidden in a groove or box;
Connections require direct access;
The pipes need to be painted;
When closing the pipes with a box, gas. pipes to the box should be at least 10-11 cm;
10-15 cm should separate the weld from the passage through the wall and base of the house;
For convenient installation and dismantling of taps, inlets, and branches, you need to install fittings with lock nuts;
Usually, the distance from gas pipes to the walls of the house is indicated in the house gasification project. If this is not the case, a distance of at least the diameter of the gas pipe is taken.

Laying a gas pipeline

Let's look at the permitted minimum distances from the gas pipeline to other communications.

From the surface of the gas pipe to the open wiring there should be 25 cm when laying parallel and 10 cm when intersecting;
For hidden wiring, these distances are reduced to 5 cm and 1 cm, respectively. The same rule applies to wiring in pipes;
Distribution and input panels with gas pipes should not intersect;
There must be a distance of at least 1000 mm to the “bare” electrical wiring busbars;
Utilities (water, sewerage) intersect with the gas pipeline no closer than 2 cm. Parallel installation is selected locally and is not standardized.

Installation of gas consumers at home

The gas water heater is installed 2 cm from a fireproof wall and 3 cm from a fire-resistant wall. The walls are insulated with a “sandwich” of 3 mm asbestos and roofing steel. The insulator must be 100 mm larger than the dimensions of the water heater on each side.
A tiled wall does not require additional protection.
The wood is plastered over a grid. Next, they are covered with asbestos or asbestos plywood, and covered with roofing steel.
The wall where the stove stands is closed from the floor. The distance from the slab to the wall is taken to be 70 mm.

Gas boilers

A gas boiler or boilers are installed in a separate furnace room or kitchen. The room where the boiler is located must be equipped according to special rules. (Read Installation of a gas boiler in the house).
The wooden wall and floor where the boiler is located must be protected with asbestos sheets and roofing steel. A boiler with internal thermal insulation is not insulated from the walls.
All gas-powered appliances must be equipped with a chimney. The diameters of chimneys are taken from the passports for the devices.

Laying gas pipes on the street

When laying gas pipes along the facade of a house, it is prohibited:

Weld or connect pipes under windows;
Lay gas pipes thicker than 50 mm along the wooden façade.

Installation of gas meters

Gas meters are installed in visible places with easy access for maintenance. The meter is mounted strictly horizontally or vertically. The meter should not shake or sway.

Delivery and acceptance of internal gas supply systems

Hidden work is accepted during the installation process;
The finished gas pipeline is tested by contractors together with the customer and the distribution network of the Oblgaz branch. The results are recorded in the construction passport or in a separate act.
The gas pipeline is checked with air under pressure.

Water testing is prohibited.

Checking for defects in connections is carried out with pressure: 100,000 Pa;
Checking the density of connections by pressure: 4000 Pa with a meter and 5000 Pa without a meter.
Tests are carried out with the devices turned on. The gas pipeline is in good condition for tight connections if the pressure in the pipes drops by no more than 200 Pa in 5 minutes.

Based on the tests, a report is drawn up. The act is signed by the installation organization and the district distribution network. According to this act, the acceptance committee consisting of: the customer, the installation organization, the Distribution Zone and Technical Supervision gives permission to start the gas. Gas is released into the house by the repair and maintenance service of the district, in the presence of the organization that did the installation. Next, the system is accepted into operation according to the act. Acceptance of the gas supply system for operation is formalized by an act.

If earlier everyone wanted to move to a new apartment located closer to the city center, now many dream of living in their own mansion, where it is delightfully quiet, green and cozy, where you can do whatever you want at any time of the day. Task No. 1 for villa owners is to provide the “nest” with all communications. If everything goes relatively smoothly with the supply of light and water, then installing gas pipes in a private house is a whole science. Let's get to know her.

Important Tips

How is a gas pipe inserted into a private house? When to start this process? What is needed to connect to the highway? First of all, you should know these points:

Is construction just planned? Then there is no need to rush, since the gas service will require documents confirming the right to the building. And if the house has not yet been “born,” then, naturally, there are no such papers. Wait for the walls, openings and roof to appear, and then go into battle!
Installation of gas pipes in a private house is permissible only after receiving a completed project and technical specifications.
Gasification of a mansion is not a cheap pleasure. The total cost, of course, depends on the length of the system, its type and complexity of the work. On average, focus on this level - 500-1000 rubles for each meter of network.
Before going to the authority, talk to your neighbors; it is possible that there will be people who want to connect to the highway just like you. Then you can “cooperate” - pay together, and later compensate part of your costs at the expense of those who have joined the system.
Even if you are installing a personal branch, sometimes you cannot do without the consent of your neighbors - they will need permission to lay pipes, and certified by a notary.

Worth paying attention! The above-ground part of the gas pipeline is usually painted bright yellow so that emergency services and users can accurately determine which communications are where.

Paperwork

Before the installation of the pipeline supplying your mansion begins, you need to do a number of steps related to paperwork. There is nothing to be done, these are the laws of our state.

Specifications

The first thing you should get from the gas service is the technical specifications. What it is? The document represents a permit to connect the house to the nearest gas supply system. In turn, according to the conditions, the licensing office guarantees that the pressure in the network will be appropriate and the service will be uninterrupted.

So, what documents should you present to obtain the document described above?

technical passport for house construction (issued by BTI);
papers confirming the fact of ownership of land and buildings;
situational plan of the site (developed by the chief architect);
state act on a plot of land.

Before taking the package of documents to the licensing authority, decide what equipment you plan to “feed” with blue fuel; it is especially important to know the type of boiler (to heat 100 m², for example, you need a unit with a power of 10 kW; to provide hot water you should throw another 20%).

This is important to know! When planning the construction of a house, keep in mind that the building, as well as other structures (garage, shed) must be removed from the underground network (the minimum distance from the gas pipe to the house is 2 m). The distance between the trees and the system should be 1.5 m. And pipes of other communications (water, electricity, sewage) should not be located closer than 1 m.

Agreement with designers

When the technical specifications are in hand, it’s time to look for a company ready to draw up a project. In most cases, a company representative goes to the site to take measurements and get acquainted with the plans for the placement of “devices” that the owners plan to connect to the system, as well as find out the brands of devices.

To draw up a project you will be asked for the following documents:

a copy of the technical certificate for the building;
technical certificates for equipment (if they are in a foreign language, then a translation);
topographic plan (with communications marks);
list of ventilation ducts, hot water taps.

Based on the submitted documents and information, the company will develop and hand over a project to you. Of course, you will have to pay for the services.

Technical supervision

The received project requires approval by Gorgaz. For an additional fee, the design company can also take on this responsibility. Many people do this because it is an additional safety net in case something is done incorrectly. The designer will immediately redo everything. Prices for approval are also steep and can vary between $300-$1000. According to the law, Gorgaz must carry out the approval within 14 calendar days. And also provide you with a chimney inspection report, sending a fire inspector, and a contract for technical supervision.

Choosing the right boiler is a guarantee that your family will not freeze in winter

Installation procedure

If all the papers are signed and handed over to you, you can begin installing the system. Only professionals can determine what diameter of gas pipe is needed for a private home, how much material will be needed, whether the system should be installed underground or above it, and so on. In addition, crashing into a highway is a serious matter, responsible, and unsafe for life. So you will have to look for an installation company, enter into an agreement to carry out a branch into your home and monitor the progress of the work. True, such an expensive pleasure also has a useful “bonus”. The implementing company will be responsible for commissioning the network, not you. This means that if the relevant authority rejects the pipeline, the installation company will have to redo everything, and at its own expense. You will only lose time.

This is important to know! To avoid troubles, allow the installation of the system to begin after signing an agreement with the installation company, and pay only after the work has been accepted by state control authorities. The only exception may be payment for a block of services related directly to cutting into the highway, which, as a rule, is carried out by a separate service.

Your mission during the installation of the branch is to provide the team with access to the territory and the house, as well as to negotiate with the neighbors (if necessary) to conduct a fragment of the network through their territory. For such a block of work, you will need to purchase special supports - the craftsmen will tell you which ones. Once installation is complete, the following steps follow:

Acceptance of communications (parties such as Gorgaz, customer and contractor take part in the process).
Sealing the meter.
Signing an agreement on the supply of blue fuel to your site.
Instructing the homeowner on how to use the gas pipeline and what safety measures to follow. This lecture is given by a Gorgaz employee who has passed a certain certification.
Opening the tap to supply blue fuel to your network branch while simultaneously checking the quality of the system.

Worth paying attention! An underground pipeline is significantly more expensive than an above-ground one, but the demand for it does not decrease - due to its high reliability and, consequently, a long service life.

If you see yellow pipes, it means that blue fuel is supplied to you through them

Installing gas pipes in a private home is a troublesome, but useful task, since gas helps us to be fed, clean and warm.
