Simplified analysis of crude oil storage tank capacity

API 620 Crude Oil Tank Pneumatic Pressure
An air pressure equal to 1.25 times the pressure for which the vapor space is designed shall be applied to the enclosed space above the water level. In the case of a double-wall tank with an open-top inner tank, where the air pressure acts against the outer tank and the inner tank is thus not stressed by the air pressure, the inner crude oil storage tank capacity may be emptied of water before the pneumatic pressure test begins. The test pressure shall be held for 1 hour.

The main contents of safety inspection for atmospheric storage tank, crude oil storage tank capacity are to see whether the tank foundation is sunk, whether the tank is corroded, whether there are cracks in the tank body and bottom, whether there is concave convex phenomenon on the top and wall of the tank, whether the accessories of the storage tank are in good condition, etc. After the crude oil storage tank capacity safety inspection and detection, the defects found in the tank should be handled according to the inspection rules in time to ensure the normal and safe use of the storage tank in the later stage.

The temperature requirements of the API 650 oil storage tank area are closely related to the evaporation loss, energy loss, crude oil storage tank capacity 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.
