Hello all,
I am currently trying to determine the proper reinforcement weld size for 2 branch connections being welded on to a pipe spool, we are currently working under B31.1 code. One branch connection is a 4X8 weldolet and the other is a 3X8 weldolet being welded on to a 8" (.322 wall) pipe. After looking at B31.1 for branch connection figure 127.4.8(E) says 3/16" is the min for NPS 3 and smaller, is this 3/16" an industry standard or there another calculation to use. Would somebody be able to point me in direction of how to size the reinforcement weld for both connections.
Thanks!
