WebJun 24, 2008 · Could you please confirm that the below formula for calculating relieving temperature is always correct for fire case: T1=T0* (P0/P1)with T in K? eg: T0=92°C P0=1.79 bara P1=5.41 bara Then, T1=278°C I ask this because we receive from subcontractor a value of 155°C for this example... WebAvailable valve size is '4M6', which correspond to different nozzle sizes for suction and discharge nozzles of the pressure relief valve. For a '4M6' valve suction nozzle is of 4" size and discharge nozzle of 6" size.

WebI suggest you to sizing PSV on fire case for pool fire case only. 6. The relieving temperature can be higher than the vessel collapse temperature. Vessel will collapse before increasing pressure reach PSV’s set pressure. Therefore, actually, PSV doesn’t provide sufficient protection. Depressuring is one of the additional protections against fire.
