Design pressure of LPG storage tank

3) After passing the internal and external inspection, conduct a water pressure test based on 1.25 times the design pressure of the storage tank and an air tightness test based on the design pressure of the storage tank. During the above test process, if there is no leakage in the welds of the storage tank and various parts, and there is no visible abnormal deformation of the storage tank, it is deemed to be qualified.

In short, inspection personnel must be trained and certified to work, and inspect according to safety technical regulations to ensure correct and full coverage inspection of storage tanks during production and operation.
