Description

This video captures the in-situ hollow specimen test on X60 pipeline steel under 300 psi hydrogen pressure. At the knee, it can be observed that the pressure inside the specimen drops to zero, indicating that hydrogen has escaped from the specimen due to a crack forming from the inner to the outer surface.
