Product advantages
Superior Corrosion Resistance
Adopts anti-corrosion coating technology to extend service life by 30% in harsh environments.
Leak-Proof Design
Integral welding and sealant systems eliminate the risk of oil seepage, ensuring environmental safety.
Cost-Effective Maintenance
Low-wear components reduce upkeep frequency and operational costs.
Customizable Capacity
Available in a wide range of sizes to meet diverse storage demands.
Oil Reservoir Tank
Our field-erected oil reservoirs can be equipped with fixed or floating roofs. A single bulk oil storage tank can range anywhere from tens of thousands to tens of millions of gallons in capacity.
Vertical Oil Storage Tank
We fabricate individual vertical tanks and complete tank farms (project costs can sometimes be reduced by building a tank farm instead of one giant reservoir). Shop-built tanks like these can be equipped with single and double walls.
Horizontal Oil Storage Tank
Our horizontal tanks are ideal for the storage of light and heavy petroleum products. We can also fabricate ASME pressure vessels.
Underground Oil Storage Tank
We manufacture horizontal shop-built tanks for underground oil storage. If your tank is destined for underground storage, we’ll give it several coatings to help it resist corrosion.

Materials of Oil Storage Tank
Steel – Steel tanks are inexpensive and widely used in factories across the United States. They can be used for both underground and above-ground storage. However, these tanks must conform to strict manufacturing and construction standards.
Fiberglass – Fiberglass tanks are sturdy and durable. Best of all, these are resistant to rust, leakage, and sediment. Similar to steel, these tanks can also be used for underground and above-ground storage.
Combination – Combination storage tanks use a double-walled and are the most sturdy and reliable storage option. The inner tank is made up of thick polyethene composite, while the outer tank is made up of galvanized steel. Both comply with pressure tests and construction standards laid down by the Federal Government.
Application
Generating power and storing energy
Oil can be used to generate electricity. This is usually done by heating up the oil to create steam, which then spins turbines. These turbines are connected to generators that create electric energy. Electricity is used in the industrial industry to power important machinery and other components needed for operations. Stored oil can act as a consistent energy supply.
Manufacturing and distributing chemicals
Crude oil and other raw materials can be stored and further processed into chemicals which are then distributed. Throughout this process, tanks are used to make sure oil is stored in the safest way.
Refining and processing oil
Crude oil can be separated into its components to create valuable products like diesel. Like when manufacturing chemicals, tanks ensure safe storage during the process.
