B31.1 boiler piping
B31.1 boiler piping
(OP)
We provide NDE services to several clients, we have one that quoting a new boiler install , the owner provided a list of welds to be x-rayed which includes 815 socket welds sizes 1/2-1.5" , I have done this is the past to check for pull-back , socket welds are fillet welds ,we usually dye pen. these, we have done several boiler projects and always dye pen'd sockets , I don't have a B 31.1 code handy , does B3.1 require RT on socket welds . we will do whatever the owner wants but if its not required I like to be able to show that and save them some $.





RE: B31.1 boiler piping
The code requires the gap to be checked BEFORE welding...not after. So RT to check for gap (or pull back)is a moot point and not required by the code.
RE: B31.1 boiler piping
MT or PT for socket welds of all sizes and thickness for service above 750 deg F (see Table 136.4)and VT for all other service conditions.
