The relationship between design pressure and operating pressure: Which standard specification does it come from?
Thread Content
As shown in the figure above: Which standard specification specifies the relationship between design pressure and operating pressure? Thank you
There is a provision on page 13 of GB 50316, which is specific to the piping discipline; it’s different from this one, so you may want to take a look
This is an internal standard of the design institute; it must have come from some training session, from a PowerPoint prepared by some instructor.
HG-T 20570.1-95 \"Determination of design pressure and design temperature for equipment and piping systems\" specifies clear requirements for design pressure and design temperature
