RT4 for hydrogen?
RT4 for hydrogen?
(OP)
I saw a pressure vessel used to conserve hydrogen (generated by a small electrolysis h2 generator) for an industrial process (to supply H2 for a H2 cooled generator in power plant). The U plate says MAWP 300psi@200F/ MDMT300psi@-20F, "FOR HYDROGEN" and RT4. The operation pressure is much lower than the MAWP.
Is it OK to use a pressure vessel(ASME VIII DIv 1) for hydrogen with RT4? I thought it should be highly inspected with RT1.

I don't recall that the Code requires any particular degree of RT for H2 service.

The problem with sloppy work is that the supply FAR EXCEEDS the demand
