Description
About us: PE80 natural gas pipes are used in the 4 bar pressurized regions of the natural gas lines. The natural has lines consist of 20 bar steel pipe, 4 bar intermediary line and 0.4 bar indoor lines. The polyethylene pipes with the composite structure in the 20 bar regions are started to be used for trial purposes. Its usage will become widespread after the standards are developed. The studies on the indoor composite pipes which will not affect from the fire are still going on.

Polyethylenes are divided into 3 groups according to their densities as Low Density, Medium Density and High Density. Although the pipe resistance and stiffness increase from the bottom to the top, in contrast, its flexibility and impact strength increase. Because the natural gas pipes are more flexible and their impact strength are higher than the high density ones, they are recommended. Natural gas pipes are in PE80 class. The environmental strength value to be reached in the medium density is 8.0 MPa for now. When this level increases, the wall thickness will decrease and the fluid quantity passing through will increase. Because these pipes are from SDR11 class, when they are used for water, they can be used at 4 bar pressure in the natural gas line by changing the safety coefficient from 1,25 to 2,5 when used in PN 12,5 bar. Because the polymer chain is effected from the hydrocarbon structures, the safety coefficient is selected as high.
