GB150 - allowable overpressure?
GB150 - allowable overpressure?
(OP)
I am designing a pressure relief valve for a gb150 vessel. I need to know the allowable overpressure for this standard in the fire case. Is it similar to ASME Sec VIII (20%)? I cannot find this information anywhere. I would also need justification for using 20% if this is possible.

If you have current GB-150....see Chapter 7,Safety Accessories,Clause 146
Also Annex 5 for design calcs.

Chapt.7 says 0% however Annex 5 gives you a 30% range if it is in a non-fire area with a non-flammable liquid.
Annex 5 also gives you calculations for all others.
So you need the book as there are exceptions
...Always,sometimes,maybe,except. Hmmm,sounds familiar.

Yes,it is expensive and painful. Check the first web site I listed.
If you do not,the Chinese will hold it on the dock. It can get extremely expensive.
