ISO 630 Gr E275 plates API Std 650 uplifting tanks
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 uplifting 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.
API Std 650 uplifting tanks Visual InspectionUpon completion of all the foregoing tests, the pressure in the tank shall be released and a thorough visual inspection shall be made of both the inside and outside of the tank, giving particular attention to all internal ties, braces, trusses, and their attachments to the walls of the tank. Anchors shall be checked for snug tightness and adjusted if required. Anchor threads shall be fouled by peening or tack welding to prevent loosening. In lieu of thread fouling, double nuts may be used.Rate of Water Filling and Water TemperatureThe rate at which water is introduced into a tank for a hydrostatic test shall not exceed 3 ft of depth per hour. The foundation, venting equipment, or other conditions may limit the water filling to a lower rate. Pressure shall not be applied above the surface of the water before the tank and its contents are at about the same temperature.
In order to prevent the deformation of the bottom of metal vertical storage tank, API Std 650 uplifting tanks during welding, the number of welders should be reasonably distributed. When welding metal vertical API Std 650 uplifting tanks, personnel and welding position shall be reasonably allocated according to the actual situation of welding personnel, and random welding is not allowed.
