We purchased several 30" flanges for ASME application. The flanges came in stamped ANSI B16.47 Class "E". They are ffso flanges. Are these acceptable to use per Code?
I am using channel rolled with legs in as external stiffeners due to vacuum on a horizontal vessel. Is it permissible under ASME Sect. VIII to drill 1/8" dia. weep holes at the low point for leak detection?
When performing nozzle reinforcement calculations per UG-37, why does the formula for A2 change from 5*(tn-trn)*fr2*t or tn to 2*(tn-trn)*fr2*L (length nozzle projects outside vessel). I am using Compress and cannot find this in the Code book.
When a level transmitter spud (its thickness greater than the head or shell into which it is welded) is welded into an ASME pressure vessel, would this spud need reinforcement calculations per UG-36(c)? I question this because the spud will always be plugged or have transmitter installed...
