API 650 flat-bottom steel tanks emergency overflow drains

In order to ensure the safety of the vertical storage tank, API 650 flat-bottom steel tanks, the supplier should inspect the tank carefully before delivery. The failure of the tank body is mainly due to the weld and crack of the product. The inspection of API 650 flat-bottom steel tanks, vertical storage tank weld and microcrack is mainly to inspect the appearance forming quality of weld. The inspection contents include weld leg height, undercut, welding deformation, weld bead, arc pit, weld straightness, etc., as well as the internal quality of weld, such as slag inclusion, porosity, incomplete penetration, crack, incomplete fusion, etc.

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 flat-bottom steel 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.

The liquid level of API 650 oil storage tank is covered by floating roof. The storage liquid of API 650 oil storage API 650 flat-bottom steel 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 650 flat-bottom steel tanks storage of high-grade gasoline, jet fuel and toxic and easily polluted liquid chemicals.
