Dear Experts,
Recently there was a big leak on a 2in-3/4in branch connection. The 3/4 flange nozzle is perpendicularly welded on to a 2in header pipe. We have repaierd it with an added Weldolet. Question: What is the minimum NPS branch connection without a Weldolet is allowable in code? Ppease quote relevant code. Thank you.
