API 650 flat-bottom steel tanks with self-supported roofs

The water dissolved in the oil will be separated out from the oil stored in the API 650 flat-bottom steel tanks for a long time, and the acidic water layer will appear at the bottom of the API 650 flat-bottom steel tanks for a long time, which will accelerate the corrosion of the API 650 flat-bottom steel tanks and cause the wall thinning and even leakage. With the increase of service life, the API 650 flat-bottom steel tanks must be inspected and cleaned regularly to check the hidden danger.

Design of a Double-wall Tank
The outer bottom, shell, and roof of a double-wall tank shall enclose an insulating space around the bottom, shell, and roof or insulation deck of the inner tank that contains the stored liquid. The annular space shall be maintained at a low positive pressure, which necessitates that the enclosure be vapor-tight. The Purchaser shall specify the design metal temperature and pressure of the inner tank and may specify the design temperature and pressure of the outer tank API 650 flat-bottom steel tanks. The Purchaser shall state the specific gravity of the content to be stored, roof live loads, wind load, earthquake load where applicable, and corrosion allowance, if any.

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