API 650 duplex stainless steel tanks threaded connections

This standard only applies to API 650 storage tanks API 650 duplex stainless steel tanks with uniform bottom support and non-refrigerated service storage tanks with a maximum design temperature of not more than 93 degrees Celsius (200 degrees Fahrenheit).

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 650 duplex stainless steel 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.

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