.......and of course, when we are doing the preliminary pipe structural analyses, we never know the reducer manufacturer and we never know the cone angle. You never can tell what the purchasing agents will buy. Most of us just used the maximum 2.0 SIF.
And for as long as there have been computer programs for structural analysis, I have been using the average diameter and the averave wall thickness with the B16.9 Standard length. But always was sure to put the SIF on the end of the previous (real) pipe length and the beginning of the next (real) pipe length. I really look forward to using the new reducer thingie - way to go COADE!!
Regards, John.
