In pressure vessel design work,the maximum allowable working pressure of the vessel is easily overlooked by the designer,and its concept is also easily confused with the maximum pressure at the top of the vessel.The paper starts with the basic concept of"pressure"in pressure vessels,analyzes the relationship and differences between the maximum allowable working pressure and working pressure,design pressure and the maximum pressure at the top of the vessel,and deeply analyzes the method of determining the maximum allowable working pressure of the vessel.The maximum allowable working pressure of corresponding components can be calculated based on the design conditions and structural dimensions of pressure components such as the vessel body,head,flange and hole reinforcement.The maximum allowable working pressure of a vessel is unique.According to relevant standards and specifications,the maximum allowable working pressure of a vessel is the minimum value of the maximum allowable working pressure of all pressure components.But this theoretical calculation process is relatively complex and has been simplified in engineering.Learning and understanding this simplification process is beneficial for designers to correctly understand the maximum allowable working pressure of vessels.The paper also introduces the application of the maximum allowable working pressure of vessels in airtightness testing and overpressure limits,as well as issues that should be noted in design work,to help designers understand this term correctly.
