API 650 mechanically-anchored tanks level gauge

The main advantages of the external floating roof API 650 mechanically-anchored tanks are large storage capacity, suitable for storing more than 10000 cubic meters of crude oil. Compared with the internal floating roof API 650 mechanically-anchored tanks, the production of external floating roof API 650 mechanically-anchored tanks is simple and the steel consumption is less. However, the central drainage system of external floating roof API 650 mechanically-anchored tanks should be installed on the outer floating roof to ensure that the accumulated water can be discharged smoothly in rainy and snowy days, and avoid sinking accident.

Inspection of Welded storage tanks Surfaces Exposed during FabricationThe edges of API 650 mechanically-anchored tanks 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.
