Why Plastic Pipes?
There are several types of plastic pipes for use in the installation of gas communications:
- Polyvinyl chloride( PVC) is still in high demand;
- Polyethylene pipes are somewhat inferior due to the fact that they are able to function only in isolated form and certain temperature conditions;
- Gas-metal-polymer pipes are much more functional;
- is also popular polypropylene. Chemical composition and resistance to aggressive external environment, does not require isolation. Low thermal conductivity does not allow the formation of condensate, and therefore does not damage the transported substance.
A distinctive feature of the gas pipes is the yellow strip applied to the surface, which does not confuse it with the rest.
It's been a long time since plastic pipes occupy a leading place among components for various systems. The gas communication, which is fully capable of evaluating all the advantages of these pipes, is also an exception:
- has a longer service life than metal ones;
- current conduction and non-contact with ground;
- light weight, which is very convenient for transportation and installation;
- reasonable price, in the end, a cost-effective communication;
- is easy to install.
Special attention should be paid to the low pressure of polyethylene gas pipelines, which allows transportation to the most remote points. Underground gas pipelines for combustible gases are also made from these pipes.
Sequence of pipes replacement in the apartment
It is strictly forbidden to work independently with gas communications, because they are classified as an increased danger. Seeking help from gas specialists will save you not only time, but will also guarantee your security.
An experienced gas man, first of all, will make a preliminary inspection of the gas system and determine the degree of wear.
Replacement of gas pipes in the apartment is carried out with strict adherence to safety regulations.
First of all, it is necessary to ensure the presence of additional ventilation in the room, shut off the gas supply and necessarily blow the pipes. Limit attention is drawn to the presence of nearby open fire, which is unacceptable and requires intervention.
After carrying out all the preparatory measures, it is possible to start disassembling the necessary section of the gas pipeline. Special tools for this will not be required, it is sufficient to have in the house an ordinary hacksaw for metal or a Bulgarian.
The insertion into the gas pipe is made by means of special fittings or overhead heating elements. Installation must be done in such a way that the design is absolutely airtight and does not let gas into the room.
Final work of
The final stage of dismantling and installation of the gas pipeline section will be a check of all necessary components, as well as the correct connection of household appliances. After this, it is necessary to remove excess air from the pipes by blowing, and the tightness of the threaded joints is also checked.
After all the manipulations, the gas is put into the system with strict control and monitoring for a few hours.
