Fabrication of API Std 650 floating-roof tanks

API Std 650 floating-roof tanks belongs to metal oil tank. Metal oil tank is a kind of vessel made by welding steel plate. The common shapes of metal tank are vertical metal tank, horizontal metal tank and spherical metal tank. The advantages of API Std 650 floating-roof tanks etc. metal oil tank are good sealing, not easy to leak, can be installed with heating and insulation function, metal tank can withstand high internal pressure, large vertical metal tank such as API Std 650 floating-roof tanks also has the characteristics of small floor space and large storage capacity.

Facilities for API 620 storage tanks InspectorThe manufacturer shall afford the inspector all reasonable facilities for testing and inspection and shall provide mutually agreeable advance notification to permit the examiner to witness all tests of the equipment and materials during fabrication, including all laboratory tests of the material to be used and all hydrostatic and pneumatic tests at the site of erection.The API Std 650 floating-roof tanks inspector shall be permitted free access to all parts of the plant concerned with the manufacture of the tank during fabrication and to all parts of the plants of material suppliers who are concerned with the manufacture of materials to be used in the tank.

API 650 internal floating roof oil tank is a volatile liquid storage tank with a combination of a dome tank and an internal floating roof structure, which is a floating roof assembled under the dome of the API Std 650 floating-roof tanks storage tank. The combination of the vault roof outside the API 650 storage tank and the floating roof inside the tank has been widely used in gasoline, aviation kerosene and more volatile chemical liquids.
