I have been wondering about how design conditions are set for pieces of equipment. I believe that design pressures are usually related to the shut-in pressures of upstream pumps right? But for design temperatures I am always seeing values that far exceed any operating conditions. For example a tower could have a normal operating temperature of 280 F but have a design temperature set at 500 F. Is this normal? Could someone help with some insight into this? Thanks.
