How to determine design pressure and design temperature
Thread Content
Knowing that the operating temperature is 20° and the design pressure is 1.6MPA, how to determine the design pressure and design temperature?

This needs to be communicated with the process and determined based on the design specifications. It cannot be determined by simply increasing by a factor of 1 or increasing by an amount.
Take a good look at GB/T150.1-2011
There is also HG/T20580-2011 six-in-one
When the pressure source comes from outside the container, in some cases the user will specify a design pressure according to the system conditions.
