pipe code question
pipe code question
(OP)
What code covers the welding of steel pipe lines coming from an ASME Section 8 stamped compressed air receiver? Is this the ANSI B31.9 code? (the system has a 130 psi safety relief pressure). Does the applicable code require certified welders to make the pipe welds?





RE: pipe code question
If this is a process plant then,
ASME B31.3 Process Piping.
Yes, the welder has to be qualified as per ASME SEC. IX.
