API Std 650 floating-roof tanks shell compression

Normal pressure API 650 storage tank: When the gas side pressure of API 650 storage tank is the same as atmospheric pressure or less than 13 atmospheres (gauge), API Std 650 floating-roof tanks is called atmospheric storage tank. API 650 petroleum storage tanks low pressure storage tank: when the pressure is greater than 13 atmospheres (gauge) and less than 0.1MPa, it is called low pressure storage tank.

API 620 Crude Oil Tank Non-pressure Parts
Welds for pads, lifting lugs, and other nonpressure parts, as well as temporary lugs for alignment and scaffolding attached to primary components, shall be made in full compliance with a welding procedure qualified in accordance with Q.6.1. Lugs attached for erection purposes shall be removed, and any significant projections of API Std 650 floating-roof tanks weld metal shall be ground to a smooth contour. Plate that is gouged or torn in removing the lugs shall be repaired using a qualified procedure and then ground to a smooth contour. Where such repairs are made in primary components, the area shall be inspected by the liquid-penetrant method. A visual inspection is adequate for repairs in secondary components.

Usually, the wind load in the API Std 650 floating-roof tanks construction area should be considered before the tank design and construction. The wind load in the API Std 650 floating-roof tanks construction area has an impact on the stability and economy of the API Std 650 floating-roof tanks. In the area with large wind load, it is safe to design the tank as "squat". When calculating the wind force, the influence of the thickness of the insulation layer of the API Std 650 floating-roof tanks, the shape of the ladder, the platform, the pipeline and the top cover must be considered.
