API 650 flat-bottom steel tanks pontoon manhole

This API 650 tank standard is designed to provide industry with tanks of adequate safety and reasonable economy for use in the API 650 flat-bottom steel tanks storage of petroleum, petroleum products. and other liquid products.

Usually, the wind load in the API 650 flat-bottom steel tanks construction area should be considered before the tank design and construction. The wind load in the API 650 flat-bottom steel tanks construction area has an impact on the stability and economy of the API 650 flat-bottom steel 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 650 flat-bottom steel tanks, the shape of the ladder, the platform, the pipeline and the top cover must be considered.

Butt-welds in piping and in API 650 flat-bottom steel tanks pipe fittings within the limitations of 1.3.2 (including the annular space of double- wall tanks) shall be inspected in conformance with API 620 oil tank standard Q.7.7.2 through Q.7.7.6. Longitudinal welded joints in piping that contains liquid shall be completely radiographed except for manufactured pipe welded without filler metal, 12 in. or less in diameter, which is tested hydrostatically or by eddy current to ASTM requirements.
