B31.3 Pipe Fabrication NDE
B31.3 Pipe Fabrication NDE
(OP)
Hello.
Would someone kindly address usual and typical weld NDE for socket weld type connections (e.g. couplings, SW fittings, etc.) which satisfies B31.3. I have come to conclude that radiography does not result in a wholly satisfactory examination of these type joints. Rather, liquid pen or mag particle would be more typical, and still satisfy B31.3 acceptance. Maybe even UT.
Would someone kindly address this issue of appropriate NDE for socket weld connections.
Thank you very much in advance.

If its something out of the ordinary, take it on a case by case basis. UT, AET, etc have all been done, but usually down the road to investigate causes of fatigue cracking.
