API 650 cylindrical liquid-storage tank siphon-type drains

The factors affecting the "small breathing" loss of API 650 cylindrical liquid-storage tank 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.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 650 cylindrical liquid-storage tank wall plate, t, required by 5.10.3 for the latitudinal unit forces, T2, acting at this level is 1.44 in.The vent pipe mouth should be 4m or more above the ground. The nominal diameter of the API 650 cylindrical liquid-storage tank API 650 petroleum storage tank vent pipe should be no less than 50mm and a flame arrestor should be installed.Enterprise style: unity, pragmatism, responsibility, and endeavorOperation Policy: realistic management, innovative technology, high quality, fast efficiency, low cost and complete service.
