5000 Cubic Meter Oil Storage Tank

 

Overview of Oil Tank

An oil tank is a storage container designed to safely hold different types of oil, such as heating oil, diesel, fuel oil, lubricating oil, or industrial oils. It is widely used in residential heating systems, commercial facilities, industrial plants, and energy infrastructure.

Common types

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.

Vertical Stainless Steel Oil Storage Tank

 

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.
