A737 grade B plates API standard 650 storage tank

Pipeline transportation of API 650 oil tank is not less than the maximum consumption of 3 to 5 days. The daily operating time of API standard 650 storage tank office buildings and fuel oil equipment is 12-16 hours; for high-end residential hotel buildings, the daily operating time is 16-24 hours.

Inspection of API standard 650 storage tank bottom: magnetic flux leakage scanning technology is used to detect the corrosion condition of API standard 650 storage tank 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 storage tank, 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 storage tank 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.

Inspection of Welded Storage Tanks Surfaces Exposed during FabricationThe edges of API standard 650 storage tank plates, openings and fittings exposed during fabrication shall be inspected carefully to make sure that any defects have been uncovered, as well as to determine that the work has been performed properly.Minor defects found may be repaired only after the inspector approves the method and extent of repairs. Materials that have more than minor defects that cannot be satisfactorily repaired shall be rejected.Spot radiographic or ultrasonic examination shall be not less than 6 in. extending along the weld. Spot radiography shall comply with the standards given in 7.15.1.3. Where spot radiographic or ultrasonic examination is applied at joint intersections, the surface shall be prepared and examined for a distance of 3 in. on each side of the intersection, making the minimum length of examination 6 in. on the horizontal weld and 3 in. on the vertical weld.
