Gentlemen, P-1/P-1 BW, .sch80 16". B31.3, requires PWHT. To pressure test, spools need weld caps at FW/FA locations, with PWHT previously performed on all other welds on the spools, 1hr hold. Would I consider PWHT on the temporary weld cap that will be cut off and no part of the actual system. Yes I know about plugs, but fittings . Looking for experienced response please.
So I guess the question is would "YOU" and why?
