Recently I have seen some pressure vessel drawings, which give the design pressure and working pressure, but not the maximum allowable working pressure. I would like to ask, what is the significance of the working pressure given here?
Working pressure is one of the basic parameters of the equipment and one of the basis for determining whether the equipment is special equipment.
There is no maximum allowable working pressure, probably because the equipment does not have a safety valve and does not require air tightness testing.
If the opening pressure of the safety valve is lower than the design pressure, the maximum working pressure is not required.
Working pressure is one of the important parameters to determine whether it is regulated and classified as a pressure vessel.
Take a good look at how the working pressure of the pressure vessel is explained in the capacity regulations. Note 1-2.
Do you still want to operate the equipment beyond the design pressure? :lol
If there is a leakage test, the maximum allowable working pressure must be obtained. Working pressure is used to classify whether it is special equipment. Generally, this working pressure is the maximum pressure that can be achieved during use.
When customizing equipment, the user should report the operating parameters according to its actual situation. If the parameter is too low, it will not meet the actual use and may be dangerous. If the parameter is too high, there will be economic losses.
It seems that according to the solid volume regulations, the container classification is based on the design pressure.
