Unique Properties of Hydrogen and Their Impact on Pipeline Design

Hydrogen Embrittlement

Hydrogen embittlement is mest critial degradation mechanism for contaminane steels. Atomic hydrogen, generated at te steel surface during transport (especially if there e e s any shavelure or contaminant), diffuses into thee metal lattie. There, it acculates at grain boundaries, inclusions, and stress concentration pointrions, reductility and fracture hardnes. Thee result is a loss of loadheaddiing capity and a higher risk of caphyphyphyphyr revure stre.
