　　Specific methods for water pressure testing of natural gas storage tanks

　　1. Classify natural gas storage tanks that require water pressure testing, as different materials of natural gas storage tanks require different methods of water pressure testing;

　　2. Secondly, when natural gas storage tanks are produced and shipped, they need to undergo relevant water pressure tests. If the seller has requirements for core extraction testing, clean water should be used during the water pressure test;

　　3. When conducting a pressure test, it is advisable to first conduct a detailed inspection of the pressure testing system, mainly checking the tightness of each system's interfaces and connection points, as well as whether the installation is correct;

　　4. The natural gas storage tank that requires water pressure testing will be prepared for pressurization and water filling. For stabilizing the pressure, it will take about 30 minutes, and then the deformation and leakage situation will be checked. If there are no abnormal situations, the pressure design can be carried out. However, it still needs about 30 minutes, and then a detailed inspection of the sealing surface will be carried out, mainly including the position of the weld and the overall leakage situation.
