Thanks JStephen. I looked in Roarks but that's probably not going to do it for me. It looks like I just flat need the ASME Pressure Vessel Code because I need to calculate minimum wall thickness required for a slight external pressure (this is a thin walled vessel, 7-12 gauge)
Thanks BigInch. I checked out B31.3 and in para 304.1.3 it does address this subject but unfortunately it only refers to UG-28 and UG-30, which I guess is part of the pressure vessel code. I think that is what I need, I just don't have it. And I don't think my boss is willing to fork over...
I'm a pump engineer so I need some help. I've been asked to determine if stiffener rings are required on some small (48" dia) vessels. They are normally operating in the 50 psig range, but can be subjected to as much as 15 in hg vacuum. I found some helpful information in the ASME Career...
