Replacing the gas pipes in the apartment during overhaul: replacement of pipes in the apartment while repairs

Overhaul called a state program that provides a set of renovations to improve the condition of the apartment building. This necessarily includes the replacement of communications: water supply, heating, gas pipeline. One of the interesting processes that require detailed explanation is the replacement of gas pipes and riser in the apartment during overhaul.

Why change the pipeline: the main reasons

Centralized gas supply - one of the modern benefits for the population living in apartment buildings. Most of the houses were built yet in the vast Soviet Union, so part of the communication is outdated and worn out. In this regard, the government has a program overhaul, in which in each apartment for free replacement of gas pipes is carried out.

overhaul The program provides free replacement of all parts of the pipeline.

There are several reasons for the replacement of the pipeline in a multi-storey apartment houses:

• gas leak was made (in this case, there is a replacement of the riser in the apartment, where the problem was found);
• worn tube, seen initial coating of pipes;
• the operating life of the pipes came to an end - it happens in homes built over 50 years ago.

Mosgaz reported that the replacement is a routine procedure. In addition, each resident of an apartment building should be at the scheduled time to provide access to your home, so as not to hinder the work of masters. Usually before such a major repair local utilities notify occupants of the house all to impending work, so everyone should be aware of a major overhaul.

replacing the need for major repairs at whether you can refuse

Often it happens that the execution of works at major overhaul causes some discomfort the residents of the apartment, who at the moment there is a replacement of the riser. Many residents are afraid of damaging other equipment, so eager to conclude an additional contract with the contractor. Unfortunately, the contractor is not obliged to sign documents with each owner of the apartment. This repair is the replacement of equipment and obscheimuschestvennogo each apartment owner must grant access to the service staff.

Abandon the work also does not make sense. The necessity is caused by a poor, worn-out condition of the pipeline, which entails negative consequences in the future.

If a resident does not provide access to the apartment, the workers will not be able to completely replace the riser. This will cause an overlap of gas supply and dissatisfaction on the part of the neighbors of the riser. Upon cancellation of the works in the apartment of the owner refused to completely block the gas.

Rules replace the gas pipes in the kitchen

Gas pipes are an essential element of the gas supply system in an apartment. They connect the main pipeline of an apartment building with a gas pipeline in each apartment. When replacing the tubes provided overhaul, carried out the procedure of dismantling of old and installation of a new gas pipeline in the kitchen. Often, service workers change the old pipe on the flexible hoses, also involves the exchange of valves. The whole procedure must be regulated in a special document.

Involvement of employees of the gas service

House, trapped in the program overhaul, equipped with outdated gas pipes, so the local service to attract workers is inevitable. The program provides security to all residents in the apartment building so it is important that the work is done by professionals. There are several criteria by which one can distinguish an employee of the gas service from others who are trying to cash in on tenants:

• employee wearing special uniforms with reflective stripes on the back there is the name of a performing service;
• the employee must provide the tenant with his certificate signed and stamped by the chief of the gas stations;
• in the certificate must present photo staff, its data service logo, the name of the management, as well as printing and hologram;
• if the resident has any doubt, he is entitled to call the number 104, to clarify the official schedule of inspections.

Jobs paid overhaul of the Fund, so from tenants do not take any money. Employees of gas service at set times come into the apartment and carried out a number of works, the result of which must comply with legal regulations. Independently engage in the reconstruction of the gas system to tenants is prohibited - because of this, on the flat may be fined.

the choice of materials requirements

Before you install new pipes throughout the house, the contractor must purchase the material. All materials must comply with the standards and requirements. Often, the gas system is located in the kitchen: it is the source for the supply of the resource through the plate, and is also sometimes used for heating by a boiler. By law, the following requirements must be met:

1. Fire safety. For gas pipe should be selected steel, copper and polypropylene tubes. Each of these materials allows to ensure complete sealing of the joints, thus leakage should arise.
2. The gas pressure. This figure should not exceed standards set by SNiPs - 0,003 Mpa.
3. Requirements to steel pipes. Products must be made from killed low-carbon steel grades CC2, CC3, and St4. for gas supply pipe must have a special certificate, confirming that the products can withstand water pressure.
4. Connection requirements. All fittings must be manufactured according to GOST. Elbows, tees, sleeves made of ductile cast iron with a cylindrical thread. Sleeves and lock nut must be steel and have cylindrical thread. Transitions and plugs are made from steel with subsequent privarkoj. All items must be factory origin.
5. a valving requirements. When choosing the material must be remembered temperature and pressure gas. To produce the locking elements apply gray and ductile cast iron, carbon steel and alloy steel, and brass and bronze.

Gas service must comply with all the requirements under the arch regulations for repair work. If you have problems or gas leaks responsible for the work of the contractor.

Stages of Works

Before the gas service employees start work on repair, scheduled inspection of each apartment will be carried out. It is on this basis it is concluded that the multifamily residential building requires replacement of gas pipes. The first thing that needs to be done to see if the house falls under the repair program - go to the gas service website and look for the address. If it is listed, in the near future is expected to visit repairmen.

Often, the entire procedure for the replacement of pipes at home lasts 3-4 days, it creates a certain discomfort for the residents, but this process provides further security. When the initial inspection of the gas officer makes a mark on what problems there are in the apartment with regards to gas equipment and pipeline. When repairmen come to the apartment, the work will take place as follows:

1. Preliminary information about the preparation. Often, this information is available on the website of the local urban gas service. In addition, workers hang ads on the house that every resident must provide the employee entering the apartment. Residents should remove completely all obstacles and kitchen furniture, which covers access to the gas system.
2. Carrying out works. Employees often carried gas service pipe replacement popodezdno. Changing the gas riser takes 4 hours of working time, therefore, every citizen should be at home during this period. Master override gas, the gas pipe is cut, mounted new tube.
3. In the next step new pipes are soldered to the gas, before it was removed therefrom remnants of the old gas by blowing.
4. Security check. With soap emulsion gasman check the integrity of welds, as well as investigating the presence of all the plugs and the condition of the connection of each apartment.

Only after security checks are permitted to let the gas through the pipes of the house. During the launch of the pipeline purged necessary to displace all the air out of him.

Terms of welds

Depending on the thickness of the wall of the gas pipe, it will be selected type welding. For example, with a wall thickness of 4 mm using electric welding or gas welding. Frequently replacing the flats during overhaul use steel pipe with a diameter of 21, 3 to 42.3 mm.

By the rules of the welds include:

• before edge procedure prepared tubes have to be cleaned from dirt and corrosion;
• if used products with a wall thickness greater than 4 mm, the bevels at the edges are made - this helps to achieve rapid melting of steel;
• Burner movement should occur from right to left: it passes along those portions of the articles which have not yet been welded together;
• around the weld should not spatter, scale, or other contaminants;
• on the surface after use should not be undercut, burn-through, and cracks.

If there are defects in the gas service employees must redo the work to ensure the safety of the tenants of the apartment.

Replacement pipe hose

In Soviet times cookers were connected via pipes to a steel pipeline by welding. Today, such a design is impractical and the overhaul of the staff will change the old pipe on the hose. This arrangement allows to move the plate on a comfortable distance in conducting independent work on repairs inside the apartment.

To attach the plate can be used several types of flexible hoses:

• of rubber and fabric;
• rubber braided metal;
• bellows metal hose.

The last option is the most common - it is sturdy and reliable. It is a metal in the corrugated casing which can flex. The tube is cut to avoid static charge between the faucet and the hose using a dielectric insert. Plate is connected with a hose, is then inserted into a metal mesh, a member of the set - it protects the burner from contamination. Both ends of the hose are tightened key.

Upon completion of work repairmen make a special act, which is signed by the owner of the apartment. The instrument contains all the changes that have been implemented by replacing the gas pipe. Also the owner of the passport is issued counter. Before signing the act should check everything thoroughly, because the signature would mean a complete acceptance of the work.
