Have the design temperature and design pressure of the production unit taken fire conditions into account?

(1) When creating the pipeline table, regarding the operating temperature and operating pressure for the safety valve pipelines: should these values be determined based on normal production conditions, or based on conditions that would occur in the event of a fire? Under normal operating conditions, the operating temperature is only 40℃ ； Fire condition 200℃ ； And the design temperature of the pipeline material used is 163℃ ； (2) Operation of the production unit, including the selection of materials for containers and pipelines, and whether fire conditions are required For example, if the design temperature is 70°C, but the temperature during a fire scenario is 200°C, how should this be taken into account?
I remember that the definitions of design temperature and design pressure are based on normal production conditions. . . . . .
Yes. The discharge temperature of a fire is definitely higher than the design temperature.
The definitions of design temperature and design pressure should be based on normal operating conditions. If the temperature during a fire is taken into account, it’s likely impossible to design it.
The design temperature and design pressure do not take fire conditions into account; instead, they consider only the highest pressures or temperatures required by the process and operating conditions.
It should be just the pressure and temperature of the process that are considered
We should only consider normal operating conditions; why consider fire scenarios? Under what circumstances did the original poster think of such a “unlucky” operating condition? Just jokingly, if we were to consider such extreme scenarios in such detail, would we not also have to take into account things like earthquakes, or wars between India and China – various unpredictable situations that are hardly likely to occur? ? ?
