Inspection of API standard 650 SUG II tanks bottom: magnetic flux leakage scanning technology is used to detect the corrosion condition of API standard 650 SUG II tanks bottom plate (such as corrosion depth and area, crack length, etc.). When there is a defect in the bottom plate of the API standard 650 SUG II 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 standard 650 SUG II 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.
