Alclad 3003 aluminum tube API standard 650 flat-bottom tanks
The liquid level of API 650 oil storage tank is covered by floating roof. The storage liquid of API 650 oil storage API standard 650 flat-bottom tanks tank is isolated from the air, reducing air pollution, fire and explosion hazards, and easy to ensure the quality of liquid storage. It is especially suitable for the API standard 650 flat-bottom tanks storage of high-grade gasoline, jet fuel and toxic and easily polluted liquid chemicals.
Inspection of Welded Storage Tanks Surfaces Exposed during FabricationThe edges of API standard 650 flat-bottom 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.
The specifications used in the design of large oil tanks, API standard 650 flat-bottom tanks mainly include American Petroleum Institute Standard API 650, Japanese Industrial Standard JIS B8501, British Industrial Standard BS2654 and Chinese National Standard GB50341 from a global perspective. The formulas used in each specification are based on the hoop stress in the membrane theory. Each specification is based on the performance characteristics of materials and the construction technology level of their respective countries to determine the allowable stresses and weld coefficients. Therefore, the calculation results of tank wall thickness of API standard 650 flat-bottom tanks with the same volume are sometimes quite different according to different specifications.
