For internal pressure vessel, pressure test is the purpose of the test container macroscopic intensity, the density of inspection of welded joint and sealing structure of sealing single phase motor performance. For external pressure vessel (including the vacuum container), the main purpose of pressure test is to check the density of welded joint and sealing structure of sealing performance, rather than external pressure stability of the container. Pressure test is divided into hydraulic pressure test and pressure test. Due to withstand test pressure is higher than design pressure, and the container will inevitably exist some defects in materials and welding joint, thus in the process of pressure test container leak even the possibility of cracking cannot be completely Single phase motor ruled out. From a security point of view, the pressure test should be used first hydraulic test, this is because the relative to the gas, liquid basically can be considered to be incompressible, hydraulic test, even if the container fracture, also won't lead to catastrophic explosion accidents.

For not suitable containers for hydraulic test, such as container there is no residual liquid, or because of a structure or support can't filling liquid container, pressure test can be used. To avoid catastrophic accidents when the pressure test, who asked to do pressure test of the container, the A and B class must be 100% ray and ultrasonic welding joint inspection, and shall strictly follow the "let rules" and GB150 about test pressure, test temperature, test methods and safety measures, etc. When the hydraulic pressure test with water as electric generator a general test medium, when need, also can be used not causing a danger to other liquid. Austenitic stainless steel containers with water after hydraulic test, water damage shall be cleared away, when can not meet this requirement, should control the chloride ion content of water is not more than 25 mg/L. Used gas pressure test should be dry, clean air, helium and other gases.
