Erection of API 650 welded steel oil storage tanks
API 650 internal floating roof tanks are generally called internal floating roof tanks, floating roof tanks, internal floating disk storage tanks, internal floating disk tanks, etc., specifically referring to API 650 storage tanks and oil tanks with aluminum, stainless steel, etc. The API 650 welded steel oil storage tanks inner floating roof of series material is an environmentally friendly and economical storage tank that prevents liquid from volatilizing.
Generally, the snow load in the API 650 welded steel oil storage tanks construction area should be considered before the design and construction of the tank. The snow load in the API 650 welded steel oil storage tanks construction area has an impact on the tank roof design and operation, especially in the area with large snow load, the roof load of large storage tank with large diameter increases. Anti freezing, heat preservation and waterproof measures shall be taken for the additional facilities of storage tanks, such as pumps, breathing valves, flame arresters, detection instruments and thermal insulation layers.
The API 620 large storage tank nozzle neck is fabricated by welding from 1/2-in. plate. The materials in the tank wall, the nozzle neck, and the reinforcing pad conform to ASTM A442 Grade 55. The main joints in the tank wall are fully radiographed, double-welded butt joints. The longitudinal joint in the nozzle neck is of the same type API 650 welded steel oil storage tanks but is not radiographed; however, the longitudinal joint and all other parts of the nozzle-and-wall-plate assembly have been shop stress relieved after fabrication, as required by 5.25. The adequacy of the reinforcement and attachment welds shown in Figure F-6 shall be determined.
