API standard 650 self-anchored flat-bottom tanks butt-weld
Standard API 650 tank calls for calculations based on the specific gravity of the liquid product being stored. This permits the thickness of the steel API standard 650 self-anchored flat-bottom tanks needed as well as other specifications of how the tank is built to be determined by the weight of the API 650 tank.
Allowable compressive stresses shall be in accordance with 5.5.4 except that for aluminum alloy plate the allowable compressive stresses shall be reduced by the ratio of the modulus of compressive elasticity to 29,000 for values of (t – c)/R less than 0.0175 and by the ratio of the minimum yield strength for the aluminum alloy in question to 30,000 for values of (t – c)/R equal to or greater than 0.0175 (see 5.5.2 for definitions). In all other equations in this standard API standard 650 self-anchored flat-bottom tanks where yield strength or modulus of elasticity is used, such as Equations 27 and 28, similar corrections shall be made for aluminum alloys.
The most popular standards for API standard 650 self-anchored flat-bottom tanks are API Std 650, JIS B8501, BS2654, GB50341, etc. The formulas used in each standard are derived from the hoop stress calculation formula of membrane theory. Combined with the stress characteristics of API standard 650 self-anchored flat-bottom tanks, plus the allowable stress, weld coefficient and additional wall thickness, the wall thickness calculation formula is complete. The allowable stress and weld coefficient are determined according to the material performance characteristics and construction technology level of each country. According to different API standard 650 self-anchored flat-bottom tanks standards, the calculation results of tank wall thickness are sometimes quite different.

Box making, door-to-door: fill in the packing plan: box making time, ship name, voyage number, customs declaration number, transfer port, destination port, gross weight, number of pieces, volume, door point, contact person, telephone number, etc., and arrange the train shift 1-2 days before the closing date (two days before the ship's date). Internal loading: fill in the packing plan: ship name, voyage number, customs declaration number, transfer port, destination port, gross weight, number of pieces, volume, cabin number, etc., and arrange the train shift 1-2 days before the closing date (two days before the ship's date).
Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel API standard 650 self-anchored flat-bottom tanks plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
