Polyethylene pipes are used for distribution of gas, at pressures to PH 10bar.

Materials
Polyethilene gas pipes are produced by PE80 and PE100 materials.
MDPE and HDPE marks were mostly used for the PE80 material.
PE100 polyethylene with high performances is material with higher density compared to PE80
The high performances of the material allow the pipes made of it to have thinner walls compared to the ones made of PE80, when it comes to the same working pressure.

Standards: EH 1555-2 and ISO 4437
