Hydrogen piping

Hydrogen piping, in industrial settings, is a system of pipes used to move hydrogen. Due to issues with hydrogen embrittlement, and corrosion, materials for hydrogen pipes must be carefully selected. For metal piping at pressures up to 7,000 psi (48 MPa), high-purity stainless steel piping with a maximum hardness of 80 HRB is preferred^{[citation needed]}.

Hydrogen has an active electron, and therefore behaves somewhat like a Halogen. For this reason, Hydrogen pipes have to resist corrosion. The problem is compounded because hydrogen can easily migrate into the crystal structure of most metals.

Composite pipes are assessed like:

• carbon fiber structure with fiberglass overlay [1].
• perfluoroalkoxy (PFA, MFA).
• fluorinated ethylene propylene [2].(FEP)
• Carbon-fiber-reinforced polymers (FRP)
