Design of API standard 650 anchored liquid-storage tanks
API 650 can store oil, gas, chemical, water and biofuel for some of the most common tanks in the oil industry. API 650 can store contents at a lower pressure (maximum of 2 PSI) but at much higher temperature (-40 degrees F to 500 degrees F) than the standards of API standard 650 anchored liquid-storage tanks. It can be any tank size.
The pressed-steel, round manhole with a 20-in. inside diameter shown in Figure F-8 is located in API 620 crude oil tank solid plate in spherical portion of a torispherical roof on a cylindrical storage tank 72 ft in diameter. The internal pressure, Pg, on the underside of the roof is 15 lbf/in.2 gauge. The thickness, t, of the roof plate required by 5.10.3 for the spherical portion of the roof is 1/2 in., which is exactly the thickness provided. No corrosion allowance is required. The materials in the oil tank roof plates and manhole frame conform to ASTM A283 Grade C steel; the main joints in the roof are double-welded butt joints, spot radiographed in accordance with 7.16 and 7.17.
The cost of mechanical cleaning for vertical storage tank, API standard 650 anchored liquid-storage tanks is low, almost all oil can be recovered, and the quality of recovered oil is high. The cost of manual cleaning for vertical storage tank, API standard 650 anchored liquid-storage tanks is high, the oil can not be recovered completely, and the quality of recovered oil is low. The mechanical cleaning of API standard 650 anchored liquid-storage tanks adopts fully enclosed operation, and separates oil, water and oil sand. There is no direct discharge of oily sewage and waste gas, which will not pollute the environment.
