API Std 650 aluminum storage tanks compartment sheets
Under the same sealing effect, the internal floating roof tank of API 650 oil storage tank can further reduce the evaporation loss compared with the API Std 650 aluminum storage tanks External floating roof tank. This is due to the shielding of the fixed roof and the gas layer between the fixed roof and the internal floating plate, which has more significant heat insulation effect than the double disc floating roof of the API Std 650 aluminum storage tanks external floating roof tank.
A cylindrical nozzle with a 12-in. inside diameter is located in solid plate in the sidewall of a cylindrical storage tank 60 ft in diameter so that its axis lies in a horizontal plane and forms an angle of 55° with a perpendicular to the sidewall at the point of intersection, as shown in Figure F-7. The thickness of the API Std 650 aluminum storage tanks sidewall plate, tw, in this area is 5/8 in., and no corrosion allowance is required. The total internal pressure, Pl + Pg, at the center of the opening is 26.1 lbf/in.2 gauge.
The factors affecting the "small breathing" loss of API Std 650 aluminum storage tanks are: 1. It is related to the change of temperature difference between day and night. The greater the change of temperature difference between day and night, the greater the loss of "small breathing"; on the contrary, the smaller the change of temperature difference between day and night, the smaller the loss. 2. It is related to the sunshine time of the oil storage tank. The longer the sunshine, the more the "small breathing" loss; otherwise, the less the loss.
