NACE requirements for Hydrogen Embrittlement?
NACE requirements for Hydrogen Embrittlement?
(OP)
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,
