Applications
Gas
Polyethylene is the standard material for gas distribution. Typical pressure ratings reach 80 psi for MDPE and 125 psi for HDPE.
Gas distribution
Polyethylene pipe for gas distribution is produced from 1 to 24 inch in diameter. In the United States its use is governed by 49 CFR 192; in Canada by CSA Z662. Where pressures exceed the limits of polyethylene, approved polyamide systems are used.

- LPG systems
- Propane gas piping
