Pressure vessels must never be used under excessive pressure. What pressure does the overpressure here refer to? Is it the design pressure, the pressure specified on the design drawings, or some other type of pressure?
Maximum operating pressure; if “maximum operating pressure” is not indicated on the diagram, then it is the operating pressure.
If it’s not specified, it must be work stress!
It should be the design pressure; at most, it can be considered the maximum operating pressure. Work stress should be a range of values that represent normal levels. Of course, there are safety devices; if these are not reselected, the safety device will come into action at its operating pressure – it can only reach that operating pressure.
Overpressure use refers to using it beyond the maximum operating pressure
The design pressure of pressure vessels is generally set higher than the operating pressure, and the maximum allowable operating pressure is in turn higher than the design pressure. Maximum operating pressure: It is the pressure of the equipment at its operating temperature. Design pressure: It should be higher than the pressure under operating conditions. Maximum allowable operating pressure: For devices that have been designed, there is generally a margin of safety. The maximum allowable operating pressure is the highest pressure that the equipment can withstand at the design temperature.
The maximum allowable operating pressure; if not specified, it is the design pressure.
The pressure referred to as overpressure is the [operating pressure]; there is no such thing as a maximum operating pressure. The following is taken from GB15-2011 \"Pressure Vessels\". The maximum allowable operating pressure is not the same as what you call the maximum operating pressure; what you refer to as the maximum operating pressure can at most be considered as the \"operating pressure\", while the maximum allowable operating pressure is a calculated value that has nothing to do with whether the vessel is in use or not. Maximum allowable operating pressure ≥ Design pressure ≥ Operating pressure (= ignore). Operating pressure ≤ Relief valve setting pressure ≤ Design pressure, or Operating pressure ≤ Design pressure ≤ Maximum allowable operating pressure = Relief valve setting pressure (= ignore). One should not mislead others in a serious manner simply because they haven’t understood something themselves.
