1. When the test container, the top should be a vent should be in the air in the container when charging. During the trial, the outer surface of the container should be kept dry. 2. When the pressure vessel wall temperature and the temperature single phase motor is roughly same, liquid pressure. 3. The test pressure shall be slowly rising, reach the specified test pressure, pressure maintaining time is generally not less than 30 min, then the pressure drop to 80% in the specified test pressure and and stay long enough to examine all of the welded joint and connection parts. If there is any leakage, repair and test again. 4. Pressure should be ac electric motor kept constant during inspection, shall not adopt continuous pressure to keep the pressure constant. In the process of the hydraulic pressure test shall not take the bolt or external forces are added to the pressure parts. 5. For spherical storage tanks, hydraulic test method meets the requirements of GB 12337-1998 the 8.10.4.4. Pressure test. 1. The pressure test should have security measures, the safety measures should be approved by the head test unit technology.

The safety of the pressure test, the test unit department deal with on-site supervision of the implementation of the security measures. 2. The test pressure shall be www.facebook.com/guohong.trading slowly rising, to 10% in the specified test pressure and no more than 0.05 MPa, the holding 5 min, for all the welding joint and connection parts with soap or other liquid leak detection for the first time the leak check, if there are any leaks, repair and test again. Initial leakage inspection qualified, and then slowly rose to a test pressure of 50%, if there is no abnormal phenomenon, followed by per level for 10% of the specified test pressure booster, step by step until the specified test pressure. The holding after 30 min, the pressure drop to 87% in the specified test pressure and maintain long enough, again to leak check all of the welded joint and connection parts. If there is any leakage, repair according to the above provisions after the test. 3. Pressure should be kept constant during inspection, shall not adopt continuous pressure to maintain test pressure constant. The bolt is strictly prohibited in the process of pressure test with pressure and the external force are added to the pressure parts. 4. For spherical storage tanks, pressure test method should also conform to the requirements of 8.10.5.5 in GB 12337-12337.
