Differance between B31.1 and Sec. 8
Differance between B31.1 and Sec. 8
(OP)
I have a customer that wants B31.1 and a fabricator that is Sec. 8. On the surface they appear to be one and the same but I don't know.
Is there a real differance between these 2 codes and what are they?
Thank you,
StW

-B31.1 is closer to B31.3 than VIII-1, as befits the component being designed and fabricated.
-Calculation equations are different (such as shells)
-Material allowable stresses are a bit different.
-Inspection requirements differ
to name a few.

What, exactly, is the scope of your cutomer's work..???
Is it piping...presure vessels....boilers or what ?
You state: "On the surface they appear to be one and the same but I don't know"
Have you actually reviewed these standards ?
