You were correct in your assumption. This is an ASME Code stamped vessel. So I am talking about the ASME Boiler and Pressure Vessel Code. We are contacting the vendor to find out why they stamped the flange B16.47 when it does not conform to that specification.
Actually we purchased these flanges from texas flange thru our supplier. They sent us a dimensional drawing and pressure/temperature rating. When we ordered they said it was a B16.1 type Class E flange, but that spec is for cast iron flanges. When the flanges came in they were stamped B16.47...
I have inspected the flanges and they have been stamped around the rim with B16.47 Class "E". Could this be an error by the vendor? I thought it was strange since I had never heard of this type flange in B16.47. The vendor has provided pressure/temperature rating but I don't believe the B16.47...
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.
This spud is similar to a "Rosemount" sanitary spud for a differential pressure transmitter. It is 5.98" od and has an o-ring seal at the inner face (vessel side). So the hole in the head is much larger than 2.375".
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...
