Understanding The Different Types Of Storage Tanks?

Storage tanks are essential for various industries, including chemical, oil and gas, and water treatment. They provide a reliable and safe way to store liquids and gases. Several types of storage tanks are used for different purposes. In this article, we’ll explore some of the most common types of tanks you can buy from a reputable storage tank manufacturer in Sudan.

Ground storage tanks (ASTs):

Above-ground storage tanks (ASTs) are commonly used for storing liquids, such as petroleum products, chemicals, and water. They are generally constructed from steel, fiberglass or concrete and are typically less expensive than underground storage tanks (USTs). ASTs are easy to install, maintain, and repair. They also allow for easier access for inspection and maintenance, and they have a lower risk of leaks.

Underground storage tanks (USTs):

Underground storage tanks (USTs) are commonly used for storing petroleum products, such as gasoline and diesel fuel. They are typically constructed from fiberglass-reinforced plastic, steel, or concrete. USTs are installed underground, making them less visible and taking up less space than above-ground storage tanks. They are also better protected from damage and vandalism. However, they are more expensive to install and maintain, and they are more challenging to inspect and repair in case of a leak.


Liquefied natural gas (LNG) storage tanks are used for storing natural gas in its liquid form. LNG storage tanks are typically double-walled and insulated, with an inner tank made of stainless steel or aluminum alloy and an outer tank made of carbon steel. LNG storage tanks are designed to maintain a temperature of -162°C (-260°F) to keep natural gas in its liquid form. They are used in the transportation of natural gas and for the storage of natural gas for power plants.

Propane storage tanks:

Propane storage tanks are used for storing propane gas for residential, commercial, and industrial purposes. Propane storage tanks are typically made of steel or aluminum and can be above-ground or underground. Propane storage tanks are available in various sizes, ranging from 20 gallons to 30,000 gallons or more. They are also commonly used in heating, cooking, and power generation.

Chemical storage tanks:

Chemical storage tanks are used for storing various chemicals, such as acids, alkalis, and solvents. They are typically made of corrosion-resistant materials, such as fiberglass, polyethylene, or stainless steel. Chemical storage tanks can be above-ground or underground and come in various sizes and shapes. They are commonly used in the chemical, pharmaceutical, and water treatment industries.
