Hi,
I'm in the API compressor industry (oil and gas). We use NACE MR0175 and MR0103 (deals with H2S cracking), but I was curious if there are any standards for hydrogen embrittlement. I came across a Polyeurthane compressor that has 10% hydrogen in the process. The engineer (many years ago) decided to spec out NACE MR0175 / MR0103 compliant material for the impeller. Today I had to approve a material change for something else on the unit and it made me wonder. The only problem I could see process-wise is hydrogen embrittlement, but I can't find any standards that deal with it. I did find a few research docs.
I ended up allowing 304 SS.
Cheers,
