I have come across a conflick in the weld of olets on a run pipe. The olets are 3-inch and the run pipe is 8-inch. The new olets we are using have a large bevel to fill with weld. Production wants to weld the bevel of the olet only to the wall thickness of the pipe. Inspection is requesting that the bevel be filled all the way as a branch conection is detailed in the B31.3. This increases the welding time and thus is not liked by production. The 31.1 addresses the issue, but the I can not find a referance to welding olets in the B31.3. Does any one know the requirements of weld olets to met B31.3 requirements?? Any help would be welcome.
