Regarding the design pressure of the equipment and the setting pressure of the safety valve
Thread Content
The design pressure of the equipment is generally taken as 1.1 times the maximum operating pressure of the equipment; for equipment with higher pressures, 1.05 times can be appropriately used. The setting pressure for a safety valve is generally chosen to be 1.1 times the operating pressure of the equipment; but isn’t that too close, which could pose a risk?
I mainly want to discuss my understanding of Table 4.1: The pressure setting for safety valves is primarily determined based on the range of the \"maximum design pressure\" of the main safety valves. For the other auxiliary safety valves, the maximum discharge pressure of these safety valves in case of a fire is 121%, which is acceptable when compared to the design pressure of 1.5 times used in hydrostatic testing.
Thank you. It’s just that the concepts are different; explained this way, it makes quite sense
As a supplementary note, the design pressure of the equipment is less than or equal to its maximum allowable operating pressure
