Please advise, should the gasket of this heat exchanger be used with a pressure register of a certain value?

BJS700-1.45/0.45-184-6/9-2Ⅰ I would like to ask what pressure level gasket should be used for this heat exchanger (gasket implementation standard GB/T29463.2-2009)
2.5/1.6 grade gasket
This post was last edited by WeliteW on 2021-7-14 13:32. This question is expanded on how to select and describe gaskets, involving two standards.: 1. GB/T151-2014 Page24 2. GB/T29463.2 Wrap Mat Page4
First, check what pressure level your equipment flange uses, and then match it with gaskets of the same level.
But mine is 1.45 on the tube side and 0.45 on the shell side. There are no gaskets with these two medium pressure levels in GB/T29463.2.
If you are a gasket manufacturer, you will get the gasket model that has been selected.； If you are a designer, your gasket pressure grade should be the same as the flange pressure grade, that is: Higher than the equipment design pressure and the pressure level is appropriate.
