Capable of transporting liquids and gases to the required distance without unnecessary losses. Therefore, they are successfully used in industry and utilities. Aesthetic appearance and sound insulation makes the polymer suitable for the urban environment or frequented places.
Types of gas plastic pipes
It is important to take into account the properties of the material:
- polyvinyl chloride (PVC)
- polyethylene;
- metal-products;
- polypropylene;
polyvinylchloride - a common material which is valued at an affordable cost, and ease of mounting in indoor systems. The disadvantage is that, during the chemical degradation of PVC releases toxic - chloroethylene.
Therefore, the use of this material is permitted only for the construction of highways in open country under the ground.
Polyethylene - a profitable option for cold transport of gases and liquids in private households or in the workplace. Affordability contributes to massive use of polyethylene pipes in the population.
It should take care of their isolation. When operating without isolation quickly lost strength and solidity of the product, increasing the likelihood of leakage.
Polyethylene has a much lesser frost resistance than other materials. Therefore, to create a highway in an open area with the help of their best under the ground, and supply of the building produce plastic products passing through metal tubes or using steel adapters.
metallopolimernye characterized in that the polyethylene layer is disposed in a reliable insulation. Resistant to adverse external factors, including mechanical damage. They are much more expensive than pipes made from other materials, however, is very reliable in operation.
They easily give the desired shape, which facilitates the installation and assembly of equipment. Plastic products to bend easily, taking the desired position. Are joined together by crimping or pressed fittings.
Polypropylene designed to transport gas in open terrain. Low reactivity does not allow it to deform and change the qualitative characteristics. Polypropylene does not need additional insulation, since it is resistant to ultraviolet and temperature fluctuations.
It is believed a gas permeable material, so it can not be used for wiring inside buildings.
Mounting
Flexibility promotes their hidden gasket that protects from the negative effects of ultraviolet radiation, excessive thermal expansion and preserves the integrity of the product. To prevent leakage, avoid unwanted compounds from the polymeric multimeter bay flexible tubes.
Numerous joints increase the cost of laying lines and extend operation. It is important to use the same type of materials during assembly. This approach helps to avoid occurrence of cracks and other mechanical damages that occur due to nonuniformity of structure.
Special tools and technologies that are used for welding of plastic pipes, greatly accelerate the creation of a gas pipeline.
Three methods of welding of polymer products:
- Electrofusion welding performed by melting plastic by thermal action of the electric current to the fitting. It is an economical and effective way, however, for use in remote locations need to have a mobile source of electrical power;
- welding socket polymeric compounds used for production in sewer systems and connector;
- butt welding using a special soldering most used option to create a secure connection polymer products.
Special attention is given metal pipes having small coefficient of thermal expansion of. This makes them ideal for concealed wiring inside the walls of buildings or for the private sector gas to the summer kitchen, the lodge or guest house.
Installation of metal-plastic made solely press fitting, tightly crimped with special tools. It is important to remember that the installation should be performed by qualified personnel familiar with the safety, performance materials and features.
To shut off the gas supply special shut-off valves are used. Their work is performed using the key or manually. Stopcocks not require additional sealing, since precisely fitted tightly parts are interconnected.
In the basement of the system should be open, and the installation must be carried out with a gap between the pipe and the walls. A place of passage in the walls and floors are covered with special additional protection.
Getting connecting gas heating devices or ovens, take care of the qualitative and rapid removal of the combustion products of the ventilation system of the dwelling. To do this, select the appropriate size of the air duct.
Installing the hood is held on bearing walls or partitions, which are made of materials that can not be burning. To prevent condensation on the outside walls - insulated room.
Mounting devices without connection to the flue duct is produced where each burner for about five square meters available. For a small water heater need not less than six meters, and the bathroom water heater is located in an area approximately equal to ten square meters.
If the room where the stove or water heater system, there is no necessary to ensure full access of air space, make sure you are building on top of the vent withdrawal.
Given the fact that the gas furnace, heating devices and water heating devices use saturated air with oxygen for combustion, it is important to provide free access to the room via ventilation. For this purpose, between the door in the kitchen or other room and the floor surface, create a narrow gap.
All equipment is equipped with valves to shut off the gas supply. Mounting heaters and gas stoves with incorporated desirable to extract or operating ventilation. During installation keep leaking pipes, so at the end of creating a gas supply system to check its integrity.
It is important to take into account some features of materials and areas where works are planned. Polymers amenable to chlorine, heat, and ultraviolet light. As a result, they emit heat hydrochloric acid, causing burns on contact.
Therefore, plastic products are insulated with special materials, and highway gas pipeline in an open area located underground. Laying of underground lines is necessarily spent with warming. It is forbidden to place the line in concrete structures and poorly ventilated tunnels, as a result of the accumulation of the gas leak can cause a violent explosion.
Flush gaskets necessary to consider the coefficient of thermal expansion of polymer, leaving free space for this purpose and a soft tooling pipe insulation. For wiring in residential, work, production and other areas it is recommended to use plastic pipes. This material, like its analogs, labeled yellow longitudinal stripe.
Polyethylene does not chemically react with the city gas and is not exposed to chemical influences from outside. As the base material inside of metal pipes, it makes it possible to use them for gas wiring in residential, commercial or industrial buildings.
When choosing a plastic tube wiring to create a gas, it is necessary to pay attention to the quality of manufacturing and producer. They care about their reputation manufacturer guarantees a long service life of products, and provide an opportunity to exchange the defective product or refund with monetary compensation.
