At what point does the code change from sect. VIII to B31.3
At what point does the code change from sect. VIII to B31.3
(OP)
My question is, I have a ASME coded vessel with a 1" threaded coupling welded into the vessel for a drain. The client wants to unthread the existing nipple and thread a new 1" sch. 160 nipple and seal weld the threads. I have one guy telling me this is asme section 8 code work and one guy telling me it will be B31.3. What is the determing factor on this. I was taught on a vessel it was a code weld to the first bolted connection. This I'm really not sure on. thanks

You are right, the ASME VIII code jurisdiction ends at the coupling weld to the shell/head.
