Design pressure of pressure vessel
Thread Content
What should be the design pressure for a pressure vessel with a normal operating pressure of 115 kilograms?
It is generally between 1.05 and 1.1 times; when setting the safety valve, one needs to take into account the deviation in set pressure, so it’s advisable to choose a design pressure that is slightly higher – decide this yourself
In some cases, the design pressure of the entire system also needs to be considered.
The design pressure of some equipment also takes into account the risk of backpressure.
