API Std 650 aluminum storage tanks depth of fusion
The internal floating plate of internal floating roof tank of API 650 tank is different from that of open floating plate of API Std 650 aluminum storage tanks External floating roof tank of API 650 tank, so it is impossible to have rain and snow load.
Pressure Setting of Safety DevicesExcept as provided in API 620 tank 9.5 for certain liquid relief valves, the pressure setting of a pressure-relieving device shall in no case exceed the maximum pressure that can exist at the level where the device is located when the pressure at the top of the tank equals the nominal pressure rating for the tank (see API 620 tank 5.3.1) and the liquid contained in the tank API Std 650 aluminum storage tanks is at the maximum design level.Vacuum-relieving devices shall be set to open at such a pressure or partial vacuum that the partial vacuum in the tank cannot exceed that for which the tank is designed when the inflow of air (or other gas or vapor) through the device is at its maximum specified rate.
The most popular standards for API Std 650 aluminum storage 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 Std 650 aluminum storage 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 Std 650 aluminum storage tanks standards, the calculation results of tank wall thickness are sometimes quite different.
