 Pipes polyethylene gas GOST P50838-95 are made from polyethylene of the PE80 and PE100 brands. The polyethylene pipe for gas has color yellow or black with the yellow longitudinal marked strips in number of not less than three which are evenly distributed on a pipe circle.
Pipes gas polyethylene are intended for transportation of gases and air-gas mixes which do not contain aromatic hydrocarbons.
 Exclusively underground laying of polyethylene pipes for gas is allowed. Elevated and their land installation is forbidden. This results from the fact that polyethylene is not steady against long influence of an ultraviolet. The air environment, aggressive for plastic, considerably reduces the term of its service and reduces durability that does not correspond to safety measures. Pipes PE gas are not intended also for plant of gas to buildings, only steel pipes are for this purpose used.
Pipes polyethylene are made for gas in the form of bays and measured pieces from polyethylene of the PE80 and PE100 brand with thickness of walls from 2,3mm to 35,2mm.
 The gas pipes made of PE80 are calculated on working pressure from 4th to 6 atmospheres, and the pipes made of PE100, from 3 to 12 atmospheres. In seismodangerous areas where earthquakes to 6 points are possible, it is authorized to use only lengthy pipes, these are pipes in coils, bays, on drums. The same rule is followed when laying gas pipelines in settlements. Polyethylene pipes gas by means of couplings connect to mortgage heaters and welding end-to-end. Welding of gas pipes PE is carried out by special welding machines that completely excludes gas leak.
Polyethylene pipes for gas pipelines have a large supply of durability. The guaranteed service life of such pipe more than 50 years.
Gas PE of a pipe are not subject to influence of both low, and high temperatures.
Anticorrosive properties of plastic use when laying gas-distributing systems in the marshland, in the conditions of a humid climate. At the same time the polyethylene gas pipe does not demand additional isolation. The polyethylene pipe for gas does not collapse roots of trees.
PE a pipe for gas is much easier than metal therefore installation does not demand attraction of a large number of labor and mechanisms.
