Hello all,

 

Would a Carbon Steel (CS) body/bonnet MOC be acceptable for hydrogen service?

Typically, I would oppose using CS for hydrogen, but from my understanding, a full nozzle (specified as 316SS) PSV would only allow contact between the process fluid and the body of the valve during a relief scenario. Is there any field experience/standards that would oppose this? 

Cost of material is a driving factor behind this inquiry. 

 

Thanks in advance.
