Facing the future, adhere to independent innovation.

Inspection of API 650 liquid-storage tanks bottom: magnetic flux leakage scanning technology is used to detect the corrosion condition of API 650 liquid-storage tanks bottom plate (such as corrosion depth and area, crack length, etc.). When there is a defect in the bottom plate of the API 650 liquid-storage tanks, the magnetic field distribution will change and the sensor can detect it. The bottom of the oil tank should be free of foreign matters and dry during testing. Weld inspection of API 650 liquid-storage tanks bottom plate: when vacuum leak test method is used to detect the tightness of oil tank bottom plate, soap water shall be applied to the weld and vacuum box shall be covered for observation

Changes in Tank ShapeIf in any of the foregoing tests there is an excessive rise of the bottom of the tank around the boundary of contact with grade, or off its foundations, or if any of the specified conditions of test loading cause other appreciable changes in the shape of the tank, the design shall be reviewed and means shall be provided in the tank for holding the shape within permissible limits under all conditions of loading,API 650 liquid-storage tanks. Additional TestsThe tests prescribed in API 620 tank 7.18 are believed to be sufficient for most tanks constructed according to these rules; if, in the opinion of the designer, additional tests are needed to investigate the safety of a tank under certain other conditions of loading, as determined from the design computations, these tests shall be made on the tank involved in addition to the tests specified in this standard.
