Leading Stainless Steel Storage Tank Manufacturers

Stainless steel is a type of iron alloy that contains a certain percentage of chromium to give this material corrosion-resistant properties. Stainless steel storage tanks vary in shape and size depending on the amount of liquids or compressed gasses they have to store. The storage capacity of these tanks can range from few liters to thousands of gallons. The tanks that are used in industries have several inlets and outlets for easy mixing or blending of the products. The construction of stainless steel tanks can vary depending on the application these are used for.

Properties of Stainless Steel

• Stainless steel is an alloy of iron, and like most other types of steel, it is made of carbon and iron.
• 10% chromium is mixed in to give corrosion resistance to this alloy.
• Stainless steel is the most widely used material in many industries due to its desirable properties.
• This material is highly durable and has high strength.
• Stainless steel has increased formability, easy fabrication, and long-lasting material.
• It has low and high temperature resistance and needs low maintenance.
• Stainless steel is environmental friendly, with great recycled properties and an attractive appearance.
• This material does not needed to be painted, coated or treated.

Grades of Stainless Steel in Tanks

Stainless steel has a wide range of grades, and each grade is known for its specific properties and performance. In storage tank fabrication, three grades of stainless steel are used. These are as follows:

Stainless steel 304 and 304L

This grade is made of 18-20% chromium, 8-11% nickel, and 2% manganese. It is the most commonly used grade because of its high corrosion resistance. It is also used in many applications because it is less expensive compared to other grades.

Stainless steel 316 and 316L

This grade contains 16-18% chromium, 10-14% nickel, 2-3% molybdenum, and 2% manganese. The addition of molybdenum makes it more resistant to corrosion; therefore, this material is used in tanks in highly corrosive environments.

Duplex stainless steel

Duplex stainless steel contains 20-28% chromium, 2-5% molybdenum, ad 5-8% nickel. It is a combination of austenitic and ferritic structures. It is highly resistant to corrosion and good for use in tanks that contain fluids such as chlorides.

Types of Stainless Steel Storage Tanks

Stainless steel storage tanks can be customized according to their function. These can be single-walled or double-walled, horizontal or vertical, and insulated or heated.

Single-Walled Tanks

• These are the simplest cylindrical stainless steel tank.
• They can be placed vertically or horizontally depending on the application.
• The single wall helps to prevent corrosion of these tanks.
• These tanks are used to store water for domestic use and also in manufacturing plants with liquid raw materials.

Double-Walled Tanks

• Double-walled tanks are used in cases where spillage is a risk, such as oil spillage prevention.
• One or both walls of these tanks are made of stainless steel, depending on where corrosion resistance is needed.
• Some double-walled tanks have insulation between these walls.

Stainless Steel Clad Tanks

• Large stainless steel tanks with thick walls are too expensive and impractical to use.
• Therefore, this tank is constructed with carbon steel plates and a thin sheet of stainless steel cladding.
• The carbon steel plates are subjected to static load, and the cladding is for corrosion prevention.

Jacketed Stainless Steel Tanks

• Jacketed steel tanks are used in processes that require additional cooling or thermal stability.
• The hot or cold air flows between the sheets of stainless steel plates.
• Three types of jackets are available. These are conventional jacket, dimple jacket, and half-pipe coil jacket.

Stainless Steel Process Tanks

• This stainless steel tank is used in industrial plants for mixing, dissolving, or homogenizing the ingredients.
• These tanks contain an agitator or mixing head.
• Other instruments are installed in these tanks for controlling parameters such as temperature, pressure, etc.

High-Pressure Tanks

• Tanks used for domestic and commercial applications have low pressure to ensure the safety of workers.
• Certain certifications are added to high-pressure stainless steel tanks.

Compressed Air Tanks

• These tanks are used in industries with highly compressed air.
• Stainless steel tanks are used as air receivers.
• In these tanks, wet air is trapped and moisture is drained inside the vessel.
• As air and moisture are present in this vessel, corrosion-resistant materials should be used in these tanks.

Applications of Stainless Steel Storage Tanks

Stainless steel is a versatile material; therefore, it is used for a variety of applications. Some of the applications of stainless steel tanks are as follows:

• Stainless steel tanks are used as cold storage. Certain materials are resistant to low temperatures; therefore, these tanks are the best to store such materials.
• Many medical instruments and medicines are stored in stainless steel tanks.
• Stainless steel tanks are also used to store food items.
• These tanks are best suited for storage of certain reactive chemicals and other waste products.
• Stainless steel tanks are used for outdoor storage such as with oils.
