AWWA Flanges
AWWA Flanges
(OP)
I need to solve a 42" shell 'split' conection in a pressure vessel using two 42" AWWA C207-1 flanges.
To do an evaluation of stresses I'm looking for the steel of this flanges.
This PV will have 30 psi of internal pressure design.
Can anybody inform to me which is the steel of this flanges, to do the calculation?
Thank you in advance.

I would ask my supplier for a mill test report of some kind. Watch out for typical properties on these reports.

RE: AWWA Flanges
Check to see if the flanges would have whatever data reports you'd need for the work. Production of AWWA flanges doesn't necessarily require ASME stamps, etc.

If you go this route, you might want to pay careful attention to the Apx 2 limitations on plate flanges.
