5086 aluminum tube API standard 650 flexible liquid storage tanks

The calculated thickness of the above-mentioned wall panels required by the hydrostatic pressure is also It API standard 650 flexible liquid storage tanks should be increased by the same ratio, unless special analysis is performed to determine the seismic overturning moment and the corresponding stress at the bottom of the wall of each layer of API 650 tank.

Weld inspection of API standard 650 flexible liquid storage tanks, vertical oil tank wall plate: In the welding inspection process of oil tank wall plate, attention should be paid to the defects of thick wall plate, such as incomplete penetration, incomplete root fusion and cracks. If there is a root incomplete penetration defect, it is necessary to open the weld joint with carbon arc air gouging and grinding machine grinding, or even weld through, and then weld again after the defect is removed.

Data Required from Manufacturer on Completed TanksIf specified in the purchase order, the Manufacturer shall supply marked copies of plans (or a separate sketch) showing the location of all plates, with a means of identifying each plate with the heat numbers. These markings shall be checked by the inspector.
