A841 Gr B plates API Std 650 welded steel storage tanks
The welded steel API 650 storage tank API Std 650 welded steel storage tanks is designed, manufactured and installed on the surface according to the API standard system classification. API 650, API620 and API 12D belong to the API standards for professional construction.
With the continuous development of large-scale oil storage tanks, the foundation of API Std 650 welded steel storage tanks has also continued to grow. Among them, API Std 650 welded steel storage tanks vertical oil tanks are storage tanks commonly used to store crude oil, diesel, gasoline and other oil materials. This type of storage tank is set up as a cylindrical shape. The bottom of the tank is a circular flat bottom plate, and the load surface of the oil tank is basically horizontal, which can generally be regarded as a uniform load, and has greater flexibility.
Inspection of Welded Storage Tanks Surfaces Exposed during FabricationThe edges of API Std 650 welded steel 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.
