A285C plates API Std 650 ground-supported liquid storage tanks

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. A copy shall be attached to the Manufacturer’s report.Check of Stress-relieving OperationThe API Std 650 ground-supported liquid storage tanks inspector shall check any thermal stress-relieving operation and shall be satisfied that the temperature readings are accurate and that the procedure conforms to the applicable requirements of these rules.

Under the action of the earthquake, API 650 storage tank is mainly damaged by the phenomenon of the lower part of the API Std 650 ground-supported liquid storage tanks tank wall. Therefore, the key point of seismic calculation is to prevent the tank wall from buckling under axial pressure.

Generally, the snow load in the API Std 650 ground-supported liquid storage tanks construction area should be considered before the design and construction of the tank. The snow load in the API Std 650 ground-supported liquid 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.
