Welded Branch Connections - Parameters of Design
Welded Branch Connections - Parameters of Design
(OP)
Hi everybody,
I'm amazed with the manner ASME B31.8 treated with welded branch connections. As you can see in appendix F, all of the parameters are geometrical and nothing is related to the forces and moments that would be exerted to the branch point (similar situation in ASME B31.3). Does anybody know about the basis for these equations(non-equations)?

But there is, IMHO, difference between a branch and a pipe with regard to the loadings. There is forces and moments from other (e.g. due to expansion) components that may exert in the branch point, isn't it?

What does that mean? If we design reinforcing pad based on the Appendix F and analyze the branch by, say Caesar II, is it possible to have stresses higher than allowable, at the junction node, based on the forces and moments and corresponding SIF?
