Factors which contribute to hydrogen disbonding of pressure vessels for hydrogen service are discussed in terms of both materials processing and service. Current test methods including high temperature high pressure hydrogen charging in an autoclave, high temperature high pressure hydrogen charging utilizing a one sided exposure and cathodic charging are discussed covering details of geometry, charging methods and feasibility. Finally, recommendations are made for a test methodology which better simulates actual refinery conditions and behavior.
