API Std 650 self-anchored flat-bottom tanks greater than 60 m (200 ft) in diameter

API 650 is constructed from carbon steel, austenitic duplex stainless steel, and API Std 650 self-anchored flat-bottom tanks aluminium A Welding Certification is stipulated by American Society of Mechanical Engineers (ASME), Section 10. There is a required inspection, no third party. The inspection cost is the cost of the NDE.

Shell Stiffening Rings for Tanks That Contain Liquid: Internal or external shell stiffening rings may be required to maintain roundness when the API Std 650 self-anchored flat-bottom tanks is subjected to wind, vacuum, or other specified loads. When stiffening rings are required, the stiffener-to-shell weld details shall be in accordance with Figure R-1 and R.3.5.2 through API Standard 620 R.3.5.5. Three-plate laps or butt-weld junctions in the tank bottom shall be not closer than 12 in. from each other and/or the butt-welds of the annular plate.

For the welding of API Std 650 self-anchored flat-bottom tanks bottom, attention should be paid to the slag removal and drying of the welding joint before welding, and there is no sediment and oil contamination in the lap joint of steel plate. The manufacturing quality and production efficiency of the central plate can be obviously improved by adopting the rolling central plate. The butt joint is used between the rolling plates to improve the installation conditions of the central plate at the bottom of the API Std 650 self-anchored flat-bottom tanks. The welding sequence of the central plate is from the center of the central plate to the surrounding.
