Tee Trunnion

Tee Trunnion

Tee Trunnion

(OP)
Hi All ,

I would like to hear your opinion about trunnions on tee's?
Is it OK to have trunnion on tee?
Does anyone knows about any reference on this topic or calculation procedure?
Is it OK to use Kellogg's calculation procedure for trunnions on straight pipe?
I would say no, since Kellogg's calculation does not considers branch/opening on the opposite side of pipe.

Thanks.

RE: Tee Trunnion

If you want a definitive ansswer you would need to use FEA.

RE: Tee Trunnion

As C2it says - best way is to use FEA. Remember that the Kellogg calculation for trunnions is circa 60 years old and there are now more appropriate methods for assessing trunnions. The Kellogg method is known to be non-conservative for trunnions applying circumferential bending moments to the pipe for example.
