Do elbows provide vacuum support
Do elbows provide vacuum support
(OP)
I am designing a DN1050 pipe run for vacuum conditions. Calculations per ASME VII-1 UG28.
The question is. Do elbows count as support points and the length between support Ls can start at elbows? Or do support rings have to be added to elbows?
Also how to calculated the external pressure rating of an elbow?

L is important if the pipe is not thick enough and support rings are required. I have worked back from value A where the pipe is thick enough to get a required L.

2. what is the wall thickness?
Sometimes its possible to do all the right things and still get bad results
