EN 10025 S275J2 plates API standard 650 flat-bottom tanks
Oil, Gas, Chemical, Water, and Bio-Fuel storage. Maximum of the most common welded steel tanks used in industry are designed following API 650. Tanks typically found in Refinery API standard 650 flat-bottom tanks tank farms, Terminals, Pipelines, and other process facilities use these tanks.
The API 620 large storage tank nozzle neck is fabricated by welding from 1/2-in. plate. The materials in the tank wall, the nozzle neck, and the reinforcing pad conform to ASTM A442 Grade 55. The main joints in the tank wall are fully radiographed, double-welded butt joints. The longitudinal joint in the nozzle neck is of the same type API standard 650 flat-bottom tanks but is not radiographed; however, the longitudinal joint and all other parts of the nozzle-and-wall-plate assembly have been shop stress relieved after fabrication, as required by 5.25. The adequacy of the reinforcement and attachment welds shown in Figure F-6 shall be determined.
Usually, the soil resistance of the foundation should be considered before the design and construction of API standard 650 flat-bottom tanks. The soil endurance in the API standard 650 flat-bottom tanks construction area plays a decisive role in the basic cost of the tank. In areas with high soil resistance, not only the cost of foundation treatment can be greatly reduced, but also the ratio of height to diameter of storage tank can be obtained. Therefore, the investment cost of the API standard 650 flat-bottom tanks can be greatly saved in the area with large soil resistance.
