ASME B16.9 BW Fittings - Interpretation about the desing proof test
ASME B16.9 BW Fittings - Interpretation about the desing proof test
(OP)
I have purchased some big stainless steel reducers designed according to ASME B16.9.
In order to qualify the desing, I have asked to the manufacturer the proof testing, but I got a certificate relevant to a carbon steel reducer.
So my question is: can a proof test certificate relevant to a carbon steel fitting be used to qualify a stainless steel fitting?
What is the correct interpretation of Para 9.3.4 about steel grade?
Thank you in advance to everybody.

Interesting question. I would tend to think it's fine, but I can imagine some situations where it might not be. Maybe you should request an interpretation from ASME.

I have already asked and interpretation to ASME, and they reply to me that they will take care of the question during next commitee meeting (next month).
Once I will have the reply, I will post it.
