A container for storing crude oil or other petroleum products. Used in refineries, oil fields, oil depots, and other industries. The oil tank area consists of multiple oil tanks. Each oil tank area generally stores one type of oil.
Classified by materials
1. Divided into three types based on materials: steel, reinforced concrete, and masonry. Steel oil tanks are available in vertical (including arch top and floating top cylindrical), spherical (spherical), and horizontal (cylindrical) forms. The vertical dome roof oil tank is composed of a spherical crown shaped tank top and a vertical cylindrical tank wall, mainly used for storing non-volatile oil products such as diesel and similar oil products. The most commonly used volume is 1000-10000m ³.
A floating roof oil tank is composed of a floating roof floating on the surface of a medium and a vertical cylindrical tank wall. The floating roof rises and falls with the increase or decrease of the storage capacity of the medium in the tank. There is a circular sealing device between the outer edge of the floating roof and the tank wall, and the medium in the tank is always directly covered by the inner floating roof to reduce the volatilization of the medium. Mainly used for storing volatile oil products, such as gasoline and similar oil products. The capacity of floating roof oil tanks is generally relatively large. Floating roofs are divided into single disc floating roofs, double disc floating roofs, and float type floating roofs.
A horizontal oil tank is composed of an end cap and a horizontal circular or elliptical tank wall, usually used in production processes or gas stations. The volume of horizontal oil tanks is generally less than 100m ³;.
Divided by structure
2. According to the structure, there are mainly crude oil storage tanks, fuel storage tanks, lubricating oil tanks, animal and vegetable oil storage tanks, etc.
Avoid foundation shear damage. According to the nature of the stored oil, it can be divided into heavy oil tanks and light oil tanks. At the same time, attention should be paid to the changes in the surface soil around the tank, which can be divided into above ground, semi underground, and underground types according to the burial depth. To prevent rapid settlement of the tank, if the steel oil tank is buried underground or semi underground, a protective wall must be installed to withstand soil pressure.
The oil tank area consists of multiple oil tanks. Each oil tank area generally stores one type of oil. The oil tank area should have fire-fighting, lightning protection, and anti-static facilities. Fire embankments need to be built in the above ground oil tank area. Continuous settlement observation work should be carried out.
