A283 Gr C plates API Std 650 SUG III tanks

API 650 storage tank stipulates that if the thickness of the lower wall panel obtained by calculating the anti-overturning moment is greater than the thickness of the API Std 650 SUG III tanks hydrostatic pressure test (both do not include the corrosion allowance).

Usually, the soil resistance of the foundation should be considered before the design and construction of API Std 650 SUG III tanks. The soil endurance in the API Std 650 SUG III 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 Std 650 SUG III tanks can be greatly saved in the area with large soil resistance.

Testing the Outer Tank: While the test pressure is being held, all welded seams and connections in the outer shell and roof shall be thoroughly inspected with a solution film unless they were previously checked with a vacuum box. The API Std 650 SUG III tanks air pressure shall be released. Pressure relief and vacuum relief valves shall be checked by applying the design gas pressure to the outer tank, followed by evacuation of the outer space to the vacuum setting of the relief valve.
