1. The role of undergroud oil tank :

Oil tank is a container for storing oil, and it is the main equipment of oil reservoir. Suitable for storage of gasoline, diesel oil, heavy oil and all kinds of petrochemical raw materials used in industrial or civil facilities.
We have D1, D2 pressure vessel manufacturing qualification of the storage tank manufacturer, can produce 10~100 cubic meters of the ground horizontal storage tanks, semi underground storage tanks, underground tanks and vertical storage tanks.
1. Capacity:100-20000L
2. Optional material: 316L/ 304 stainless steel ,Q235B/Q345R carbon steel
3. Type:vertical or horizontal
4. We can design and produce Vertical stainless steel storage tank according to your requirements.

2. Function

The differences between the underground oil storage tank and the above oil tank are as followed: the ground tank is not subject to soil corrosion, long life, construction and maintenance are convenient, less investment, easy to check, but there is not Security, can not be located in the urban areas, and covers an area of large, fire equipment and more. The buried tank due to set in the ground, a reliable fire, explosion-proof capacity. This allows the safety distance between the tank and the safety distance between adjacent buildings to be shortened, saving land resources. At the same time, it also reduces the total cost of the project. And fast construction, fire equipment is simple. But there are storage tanks to withstand the pressure of casing, groundwater buoyancy and soil erosion and other unfavorable factors, as well as leakage is not easy to find and repair inconvenience and other shortcomings.

3. Application

According to the statistics of the survey data at home and abroad, the installation of the buried tank is easy to save even if the oil tank is ignited. In addition, the buried tank Compared with the ground tank, the area is small because it does not need to set the fire embankment, eliminating the need for the area of the fire embankment, if necessary, can also be buried in the fuel tank and lane, Which can also reduce the area occupied by the gas station.On the other hand, it is also necessary to set the cooling water for the ground tank, and it is necessary to set the cooling water for the ground tank, And the oil tank by ultraviolet radiation, the temperature changes, bringing the oil evaporation and loss and other issues.

4. Principle of Underground Oil Tank

Mainly based on gravity (oil gravity) atmospheric pressure (external atmospheric pressure and the relationship between the pressure inside the tank) to operate.
