API standard 650 anchored liquid-storage tanks mixers
The characteristics of the API standard 650 anchored liquid-storage tanks internal floating roof structure of API 650 petroleum storage tanks: the inner floating roof or inner floating plate refers to the floating roof that floats on the liquid surface of the oil tank with the oil and liquid up and down. The API standard 650 anchored liquid-storage tanks inner floating roof is used to cover the liquid. The surface is currently recognized as the most ideal and most economical and practical way to reduce oil evaporation loss.
The tank 20-in. inside-diameter nozzle shown in Figure F-6 is located in solid plate in the sidewall of a cylindrical storage tank 148 ft in diameter in an area where the thickness of the wall plate, tw, is 11/2 in. A corrosion allowance of 0.10 in. is required on all surfaces of the tank exposed to the stored liquid. The total internal pressure, Pl + Pg, at the center of the opening is 24.9 lbf/in.2 gauge. The thickness of the API standard 650 anchored liquid-storage tanks wall plate, t, required by 5.10.3 for the latitudinal unit forces, T2, acting at this level is 1.44 in.
Strictly controlling the temperature in the API standard 650 anchored liquid-storage tanks can effectively reduce the volatile consumption of oil in large oil storage tanks. Because the higher the temperature in the oil storage tank, the stronger the activity of oil molecules and the greater the volatilization consumption of the oil. Therefore, the temperature in the API standard 650 anchored liquid-storage tanks must be reduced as much as possible. It is possible to reduce the direct sunlight temperature by painting white anticorrosive paint with good light reflectivity. It is also possible to use spray equipment to wash the top and wall of the API standard 650 anchored liquid-storage tanks with water flow to reduce the volatilization consumption of the oil in the storage tank.
