API standard 650 cylindrical tanks lap-welded bottom joints

The main reason of "small breathing" loss of API standard 650 cylindrical tanks is the change of atmospheric temperature. When the temperature rises with the increase of solar radiation from dawn, the temperature of oil in the API standard 650 cylindrical tanks also changes, resulting in the acceleration of evaporation speed and the increase of evaporation pressure. When the pressure exceeds the positive pressure rating of the breathing valve, the oil-gas mixture in the API standard 650 cylindrical tanks is discharged into the atmosphere through the breathing valve, which is the "exhalation" process of the oil tank.

API 650 storage tank, double-layer oil tank environmental protection advantages: ordinary single-layer steel API standard 650 cylindrical tanks oil tank is corroded by underground water and gas and electrolytic corrosion because it is buried underground all year round. The API 650 tank has a double-layer structure with a gap of 0.1 mm. The API standard 650 cylindrical tanks outer layer of FRP ensures that the leakage will not directly leak into the soil and water source.
