ASTM A216 grade WCA external floating roofs API standard 650 welded tanks for oil storage
This standard only applies to API 650 storage tanks API standard 650 welded tanks for oil storage with uniform bottom support and non-refrigerated service storage tanks with a maximum design temperature of not more than 93 degrees Celsius (200 degrees Fahrenheit).
Butt-welded joints used to fabricate large steel storage tank fittings shall be completely radiographed. Lines carrying liquid shall be hydrostatically or pneumatically pressurized at a minimum pressure of 35 lbf/in.2 and API standard 650 welded tanks for oil storage butt welded joints shall be simultaneously visually examined (hydrostatic) or solution film tested (pneumatic) for tightness. If manufactured pipe has been hydrostatically tested previously to ASTM requirements, then only circumferential welds need to be examined.
Usually, the wind load in the API standard 650 welded tanks for oil storage construction area should be considered before the tank design and construction. The wind load in the API standard 650 welded tanks for oil storage construction area has an impact on the stability and economy of the API standard 650 welded tanks for oil storage. 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 standard 650 welded tanks for oil storage, the shape of the ladder, the platform, the pipeline and the top cover must be considered.
