RUPTURE DISK FORCES
RUPTURE DISK FORCES
(OP)
Similar to method in API RP 520 for PSV's, is there a reliable and validated method of calculating the reaction force on piping at disk failure ?

RE: RUPTURE DISK FORCES
Why there is a 0.63 factor and kc+0.2 I am not sure. It does not fit any fluid dynamics that I am aware of. I was interested in whether there are any manufacturer guidelines perhaps related back to test results ?
RE: RUPTURE DISK FORCES
Of course, the flowrate through the disk is continuously changing, so you'll want to calculate the reaction force based on the initial flowrate and not the required relief flowrate. The initial flow is usually much higher, thus it creates a much higher reaction force.
