B31.3 Branch Connections
B31.3 Branch Connections
(OP)
All,
I have a situation where I need to stub into a welded 90 degree elbow with a reinforced connection. The seam weld of the elbow will be the centerline of the branch connection. The stub in will remove some weld and the reinforcement will cover the elbow weld seam. The elbow was purchased as 100% xray. The stub in and reinforcement will be to B31.3 requirements.
Does B31.3 prohibit the location of the branch connection along a weld seam? I have read throught he code and can not find any reference to this situation.
Thnaks for any help.

The fact that there was a 100% RT makes E=1. The weld doesn't exist as far as calculations are concerned.
It is not a good practice to straddle a weld seam, but i some time has to be done.
