Underground oil tanks
Underground oil tanks can come in many forms, depending on factors such as their purpose, capacity and geographical conditions. The following are several common forms of underground oil tanks:
Steel Oil Tanks: This type of oil tank is usually made of steel, which has high strength and corrosion resistance. They are commonly used to store various types of fuel, such as gasoline, diesel, and liquefied natural gas (LNG).
FRP Oil Tank: This type of oil tank is made of fiberglass reinforced plastic (FRP), which usually has good corrosion resistance and structural strength. FRP oil tanks can reduce corrosion and the impact of the external environment when used underground.
Double-walled oil tank: This type of oil tank has a double-layer structure, with the inner layer storing fuel and the outer layer acting as a protective layer to prevent leakage and contamination of groundwater. Double wall design provides extra security.
Concrete Oil Tanks: Underground oil tanks made of concrete are sometimes used and are often used in large industrial sites or for long-term storage needs because concrete has good structural strength and corrosion resistance.
Soft Shell Tanks: These tanks are usually made of flexible materials such as polyethylene (PE) or polyvinyl chloride (PVC). They are suitable for smaller capacity requirements and can be customized as needed.
These are common forms of underground oil tanks and the choice depends on the specific requirements of the project, safety standards and environmental factors.
