Relationship between valve operating pressure and nominal pressure
Thread Content
What is the relationship between a valve’s operating pressure and its nominal pressure, and are there any relevant standards? Generally, when the nominal pressure is more than 1.5 times the operating pressure, it is necessary to
It’s also related to temperature; check the P-T diagram
The nominal pressure is usually something like 10, 16, 25, right?
The selection of the nominal pressure is generally the maximum operating pressure, considering the medium temperature
Select the appropriate pipeline, equipment, and instrument pressure ratings based on the maximum temperature and pressure specified in the design.
