Abstract: This paper describes and summarizes the requirements of ASME Ⅷ-1 code and different project documents on hydrostatic pressure test for pressure vessels. It also explains the relevant inputs and settings in the calculation software PV Elite. These can provide reference for the correct determination of the maximum allowable working pressure and maximum working pressure, and then the determination of the hydrostatic test values required by clause UG-99 in the code. Finally, different hydrostatic test values obtained under different project requirements are shown through calculation examples.
