ANSI B16.5 Corrosion Allowance
ANSI B16.5 Corrosion Allowance
(OP)
Dear all,
I was sure that pressure ratings stablished in ANSI B16.5 implicitily included a 0.25in corrosion allowance and that if this values was exceded, the ratings were no longer valid.
Just to verify that, I went thorugh this ANSI and found notihing about this corrosion matter (may be I was not able to spot the proper statement!!).
So, I´ll be glad if some colleague can provide some guidance in this subject.
Thanks in advance

RE: ANSI B16.5 Corrosion Allowance
I would think the corrosion allowance is taken care of by specifying the flanges to be the same bore (inside diameter) as your pipe. That's what I do.
You certainly don't want to use Std bore flanges with XXS pipe.
