Which temperature should be used to determine the maximum shock-free operating pressure of the flange?

Normally, it is chosen based on the operating temperature, but I’ve seen people choose it based on the design temperature as well. Thank you
The design basis for pressure vessels is the design temperature, so it should be based on the design temperature! ! !
According to the design temperature, the insurance is fine, no problem.
Select according to the principle that the operating temperature of the flange is higher than the design temperature
Choose a more secure one based on the design temperature and design pressure.
