Types of Storage Fuel Tanks

• Above - ground Tanks: They are easy to access for inspection and maintenance. They are usually made of steel or fiberglass and are commonly used in industrial plants and refineries.
• Under - ground Tanks: These tanks are buried underground, offering better protection from the external environment and reducing the risk of damage from natural disasters or human - made accidents. They are often used in gas stations to store gasoline and diesel.
• Semi - underground Tanks: They combine the advantages of both above - ground and underground tanks. Part of the tank is buried, which helps with temperature control and provides some protection, while the upper part is accessible for maintenance.

Classified by Shape

• Vertical Tanks: They have a cylindrical shape and are tall and narrow. Vertical tanks are space - efficient and can be used to store large volumes of fuel. They are commonly seen in oil depots and chemical plants.
• Horizontal Tanks: These tanks are relatively short and wide, with a cylindrical or rectangular shape. They are more stable and easier to install, suitable for small - to - medium - scale fuel storage, such as in some industrial workshops or on - site fuel storage for construction projects.

• Steel Tanks: Known for their high strength and durability, steel tanks can withstand high pressures and are suitable for storing various fuels. However, they need to be properly protected from corrosion.
• Plastic Tanks: Lightweight and corrosion - resistant, plastic tanks are often used for storing small amounts of fuel, such as in portable fuel containers for outdoor equipment.
• Composite Tanks: Made from a combination of materials like fiberglass and resin, composite tanks offer good strength - to - weight ratios and excellent corrosion resistance, making them suitable for specific applications where both durability and weight are important considerations.
