Dear Durga,

Addition to your question, just share with you.

In one of project, we are using structuarl members with Pads at elbow as trunion supports not Piping, hence calculated SIF by FEM, however, to model in CAESAR, we are selecting the " TEE TYPE", Reinforced tee, RPad thickness, SIF(I), SIF (O) from FEM at all 3 location points of bend. Equivalent Pipe size also calculated.

Client considered Trunion is "TEE" < even there is no fluid inside trunion> welded connection with Elbow.

May be useful to you.

Dear experts, correct me, if my analysis technique is not correct.

It is highly conservative, but no option, as instructed by Client.

Regards
SND
