ASME Sec. VIII, Div. 1, Short Term Up-set Condition
ASME Sec. VIII, Div. 1, Short Term Up-set Condition
(OP)
ASME VIII, Div. 1 defines Design Temperature and Pressure as T and P that shall not be less than the highest Temperature and Pressure in the most severe operating condition. Some people interpret it in a way that in the short term upset condition, P and T can be higher than Design Pressure and Temperature. Does any body know whether code has any definition for "short term", or "up-set condition", or any rules or regulation for short term upset condition? I appreciate any kind of help.

As rustbuster says, if you exceed, you are in a FFS situation. Perhaps some other members here can elaborate if ASME PCC has anything to say about this.

Reasonably anticipated upset conditions count.
See also thread794-186287: Temporary "Upset" Temperature Design and thread794-258873: Transient pressure
PCC does not address this as far as I know.
