API Std 650 aboveground petroleum storage tanks base metal
Inspection of Welded storage tanks Surfaces Exposed during FabricationThe edges of API Std 650 aboveground petroleum storage 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.
Welding certification is regulated by Section 10 of the American Society of Mechanical Engineers (ASME). For both API Std 650 aboveground petroleum storage tanks storage tank API 650, non-destructive inspection is required, but third-party inspection is not required.

}Oil storage tank is an important equipment commonly used in petroleum and petrochemical industry. New API Std 650 aboveground petroleum storage tanks, metal storage tank must be tested before it can be put into use or put into storage. The common inspection methods of API Std 650 aboveground petroleum storage tanks include radiographic testing, ultrasonic testing, magnetic particle testing and dye penetrant testing. The parts and operation requirements of these testing methods are different, so they should be selected according to the required characteristics.
