API 650 special tank foundations for leak detection

The temperature requirements of the API 650 oil storage tank area are closely related to the evaporation loss, energy loss, API 650 special tank storage and storage platform tank materials and the selection of detection instruments, or the temperature of the API 650 oil storage tank area. The cost of storage has a direct impact.

Temperature Range: The provisions in this appendix are considered suitable for API 650 special tank design metal temperatures from + 40°F to –60°F, inclusive. In general, refrigerated tank primary components include those components whose failure would result in leakage of the liquid being stored, those exposed to the refrigerated temperature, and those subject to thermal shock. Further definitions of such components are provided in API Standard 620 tank R.1.4.2 and R.1.4.3.

The main reason of "small breathing" loss of API 650 special tank 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 650 special tank 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 650 special tank is discharged into the atmosphere through the breathing valve, which is the "exhalation" process of the oil tank.
