API Std 650 ground supported flat-bottom tanks local shear transfer

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 ground supported flat-bottom 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.

The temperature requirements of the API 650 oil storage tank area are closely related to the evaporation loss, energy loss, API Std 650 ground supported flat-bottom tanks storage and storage platform tank materials and the selection of detection instruments, or the temperature of the API 650 oil storage tank area. The cost of storage has a direct impact.

API Std 650 ground supported flat-bottom tanks construction must adhere to the design drawings, acceptance specifications and construction plans. If the design needs to be modified during API Std 650 ground supported flat-bottom tanks construction, it must be approved by the original design unit or Party A’s representative and relevant personnel of the supervision unit, and written visa procedures must be completed in advance. The equipment and main materials used in the oil tank construction project must have certificates of conformity and quality assurance.
