aluminum sheet 5456 API standard 650 special tank

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 standard 650 special tank 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 standard 650 special tank external floating roof tank. =====
API 650 tank has the advantages of less load on the floating plate, simple and light structure, and can save the central drainage pipe and rotating floating ladder on the API standard 650 special tank floating plate. The materials for easy construction and maintenance and sealing parts can avoid aging due to sunlight.

All oil tanks have service life. Due to the pressure of the oil stored on the tank and the corrosion of the oil and external environment on the tank, the oil storage tank will gradually become thin or crack after a long time. Due to the different materials and environment of API standard 650 special tank, the consumption of API standard 650 special tank is different, so it should be taken into account when evaluating the remaining service life of API standard 650 special tank.
