Flanged Pipe Systems - 01/17/13 07:08 PM
Hi all:
For flanged piping systems eg: Teflon-lined / glass-lined piping, how critical is modeling the flange thickness. The isos don't consider the flange thicknesses & dimension to C/L of the gasket. I am following dimensions exactly as indicated on isos.
So for the flange, I give it a thickness = gasket thickness with a rigid weight. Is this correct? How critical is the flange thickness in stresses / restraint loads etc. ?
The concern is if I model the flange thickness I have to make up the difference in pipe lengths indicated on the isos. So in that case my model wont match the isos and it's a lot of extra work.
Perhaps this is critical in a large bore piping? NPS>6" ?
Please advise. Also all flanges are rotating lap-joint flanges
Thank you kindly
