,API 650 aboveground petroleum storage tanks. test procedure
The inner tank shall be opened to the atmosphere, and a sufficient amount of water shall be added to the inner tank to balance the upward pressure against the inner tank bottom produced by the pneumatic test of the outer tank; as an alternative, the pressure between the inner and outer tanks can be equalized. API Standard 620 Air pressure shall be applied to the space enclosed by the outer tank equal to at least the design gas pressure but not exceeding a pressure that would overstress either the inner or outer tank.The API Std 650 standard published by the American Petroleum Institute (API) is designed to provide the petroleum industry with welded steel tanks for use in the API 650 aboveground petroleum storage tanks storage of petroleum products and other liquid products commonly handled and stored by the various branches of the petroleum industry.We exported 352 tons SA387GR12CL2 steel plates to Vietnam.
