Compressed Air / Gas & Hydrogen-Rated Piping — Gases & Elemental/Inorganic Misc
Named chemicals
What LibertyCES's vendor documentation shows
The H2ready hydrogen-service certification on Advanced PE is the standout and genuinely forward-looking: hydrogen is benign across all materials in the chart, but hydrogen SERVICE certification is a separate, harder credential and Asahi holds it. Two real gas-service installations exist (natural gas at BAE Dry Dock, chlorine dioxide test spools at City of Akron WTP). Carry the Full Notch Creep Test data as material-science backing: Advanced PE's minimum standard FNCT is 8,760 hours (1 year) vs 300 hours for PE 100, with a real average test result of 14,648 hours — roughly 27x the PE100 minimum. Vendor installation rule: threaded joints should not be allowed.
Materials documented for this service
- Advanced PE resin PE445584C (H2ready certified)
- PE (Air-Pro, Pro-Vent)
- Flowline chart, hydrogen at 40°C and 80°C: PP E, PVDF E, PTFE E, 316SS E — benign across the board
- Flowline chart, acetylene and carbon dioxide (wet-dry): E across PP/PVDF/PFA/PTFE/316SS
