API standard 650 aboveground steel oil storage tanks dynamic liquid hoop forces

All edges of the inner wall of the API 650 petroleum storage tank to be lined or coated must be rounded and flat to a minimum radius of 3mm. The API standard 650 aboveground steel oil storage tanks internal welding seam must be completely sealed welding, with a smooth surface and no air holes, air pockets and local protrusions. Remove welding spatter. As specified in API 650 petroleum storage tank design drawings, the seller must perform additional surface treatment.

Impact Test Requirements for Oil Storage Tanks Primary Components
All API standard 650 aboveground steel oil storage tanks primary components of 9% or 5% nickel steel shall be impact tested in accordance with Q.2.2.2 through Q.2.2.4. Impact testing is not required for primary components of austenitic stainless steel, nickel alloy, and aluminum materials. Welds in high-alloy (austenitic) stainless steel shall be impact tested if required by Q.6.3.
Impact testing of plates, including structural members made of plate, shall comply with the following:a)Impact test specimens shall be taken transverse to the direction of final plate rolling. b)Charpy V-notch specimens shall be cooled to a temperature of –320°F for A353, A553, and A645 steels for impact testing.

The main advantages of the external floating roof API standard 650 aboveground steel oil storage tanks are large storage capacity, suitable for storing more than 10000 cubic meters of crude oil. Compared with the internal floating roof API standard 650 aboveground steel oil storage tanks, the production of external floating roof API standard 650 aboveground steel oil storage tanks is simple and the steel consumption is less. However, the central drainage system of external floating roof API standard 650 aboveground steel oil storage tanks should be installed on the outer floating roof to ensure that the accumulated water can be discharged smoothly in rainy and snowy days, and avoid sinking accident.
