50ft diameter API Std 650 aboveground steel oil storage tanks

The liquid level of API 650 oil storage tank is covered by floating roof. The storage liquid of API 650 oil storage API Std 650 aboveground steel oil storage tanks tank is isolated from the air, reducing air pollution, fire and explosion hazards, and easy to ensure the quality of liquid storage. It is especially suitable for the API Std 650 aboveground steel oil storage tanks storage of high-grade gasoline, jet fuel and toxic and easily polluted liquid chemicals.

Define the welding sequence of API Std 650 aboveground steel oil storage tanks bottom plate: the welding sequence of metal vertical storage tank shall be carried out according to the procedure required by the welding scheme. Spot welding shall be consistent with the formal welding requirements, and no spot welding shall be carried out for the weld not welded. Back bar should be added to prevent deformation when welding the full length seam of middle plate, butt joint of edge plate and turtle shell joint.

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 Std 650 aboveground 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.
