What is Stainless Steel Tank？

Stainless steel tanks are widely used in food, beverage, dairy, medicine, cosmetics, and other manufacturing processes where cleanliness and purity are important. These are also used in industrial plants for storing chemicals and gasses where strong resistance from chemical degradation is required. Stainless steel is a type of iron alloy containing a certain percentage of chromium, which imparts corrosion resistance to the metal. Corrosion resistance is achieved by creating a thin film of metal oxides that acts as protection against corrosive materials.
Stainless steel tanks vary in shape and size. Depending on location and transportation restrictions on dimensions, they can be oriented vertically or horizontally.

Types of Stainless Steel Tank

Single-walled Stainless Steel Tank:
These are the simplest stainless steel tank, usually cylindrical in construction. These can be oriented vertically or horizontally depending on the application and size restrictions. Having a single wall offers protection from corrosive compounds on both the internal and external surfaces of the tank. These are mostly used in storing water for domestic use and in manufacturing plants with liquid raw materials.

Double-walled Stainless Steel Tank:
These are used for applications requiring secondary containment in case of spillage, as regulated by the EPA in its oil spill prevention programs, particularly SPCC (Spill Prevention, Control, and Countermeasure). Double-walled tanks can have one or both walls of stainless steel, depending on where the corrosion resistance is needed. Other double-walled stainless steel tanks have insulation in between. The insulation protects the product from ambient temperature variations.

Stainless Steel Clad Tank:
Constructing large stainless steel tank with thick walls are very expensive and impractical. A solution to this is to construct the tank with carbon steel plates that are subjected to the static load and pressure of the process fluid while being covered with a thin sheet of stainless steel cladding for corrosion protection. Stainless steel cladded carbon steel plates are formed by pressing and heating the two metals together. A metallurgical bond is formed during this process. Stainless steel sheets can be bonded on one side (single-side cladding), or both (double-side cladding). Aside from pressing, other techniques are available such as hot roll bonding, cold roll bonding, and explosive bonding.

Jacketed Stainless Steel Tank:
These types of stainless steel tank are primarily used for processes that require additional heating, cooling, or thermal stability. Heating or cooling fluid flows through the space between the two stainless steel plates or sheets. Heat transfer takes place through the inner wall. After heat transfer, the heating or cooling liquid returns to the utility systems (boiler or cooling towers).

Stainless Steel Process Tank:
This type of stainless steel tank is used for mixing, dissolving, or homogenizing process components or ingredients found in most manufacturing and industrial plants. The main feature of these tanks is the agitator or mixing head. There are many different agitator designs that can be used. Examples are high shear mixing heads, mixing paddles, impellers, and helical agitators. Instruments are installed for monitoring parameters such as temperature, pressure, and level. Stainless steel process tanks can have additional features such as heating and insulation by utilizing double walls.

Common Uses for Stainless Steel Tanks

Industrial Storage and Processing
Stainless steel tanks find extensive use in industrial settings for storage and processing purposes. These tanks are capable of storing a wide range of substances, including chemicals, solvents, oils, and other fluids. The resistance to corrosion and high temperatures makes stainless steel tanks suitable for harsh environments, ensuring the integrity and purity of stored materials.

Water Storage and Treatment
Water storage and treatment are vital in both residential and commercial sectors. Stainless steel tanks are widely utilized for water storage due to their non-reactive nature, which helps maintain water quality and prevent contamination. These tanks can store potable water, rainwater, or treated water, supporting various applications such as residential water storage, firefighting systems, irrigation systems, and water treatment facilities. The robust construction of stainless steel tanks ensures long-term reliability, making them an excellent choice for water management needs.

Brewing and Beverage Industry
Stainless steel tanks have revolutionized the brewing and beverage industry. Breweries and beverage manufacturers rely on these tanks for fermentation, storage, and aging of their products. Stainless steel offers a sterile and inert environment, crucial for maintaining the taste, aroma, and quality of beverages. The tanks are easily cleanable, preventing contamination and bacterial growth. Stainless steel tanks are also used for carbonation processes, blending different ingredients, and facilitating efficient distribution of beverages.

Dairy and Food Processing
The dairy and food processing industries require stringent hygiene standards to ensure the safety and quality of their products. Stainless steel tanks provide an ideal solution for the storage, processing, and transportation of dairy products, food ingredients, and beverages. Tanks with specialized features like cooling jackets, agitators, and insulation are used for precise temperature control, mixing, and maintaining product freshness. The smooth and non-porous surface of stainless steel tanks prevents the accumulation of bacteria, facilitating easy cleaning and compliance with food safety regulations.

Oil and Gas Industry
The oil and gas industry relies on stainless steel tanks for storage and transportation of crude oil, refined petroleum products, and natural gas liquids. These tanks can withstand the demanding conditions of the industry, including exposure to harsh environments and extreme temperatures. Stainless steel tanks offer excellent corrosion resistance, preventing leaks and ensuring the safety of both the stored material and the surrounding environment. They are also used for separating, storing, and treating wastewater and byproducts generated during the extraction and refining processes.

Stainless Steel Grades in Tanks

Stainless steel has a very wide range of grades for handling specific chemicals. Different grades have varying corrosion resistance, strength, toughness, and high and low-temperature performance. In the fabrication of stainless steel tanks, three grades are widely used. These are 304/304L, 316/316L, and duplex.

Stainless Steel 304 and 304L
Stainless steel 304, aside from the steel forming alloys, is composed of 18-20% chromium, 8-11% nickel, and 2% manganese. This is the most common stainless steel since it has enough corrosion resistance for most applications and is less expensive than other grades. An austenitic metallurgical structure makes it ductile and well-suited for forming a wide range of products.

Stainless steel 304L has similar chromium, nickel, and manganese content. Its difference from stainless steel 304 is its lower carbon content, thereby preventing the process called sensitization. Sensitization happens when chromium and carbon atoms alloyed in the steel react at high temperatures, forming chromium carbides. Since some of the chromium is already used to form chromium carbides, less is available for forming the passive film. These occur at the grain boundaries of the steel structure, which makes it prone to intergranular corrosion. This process is problematic when stainless steel is subjected to high-temperature processes or applications. Lowering the carbide content creates less chromium carbide formation, and corrosion resistance is maintained even at high temperatures.

Stainless Steel 316 and 316L
Stainless steel 316 contains 16-18% chromium, 10-14% nickel, 2-3% molybdenum, and 2% manganese. The added molybdenum makes this grade more corrosion-resistant than stainless steel 304. It has higher nickel content to counter the ferritic forming property of the added molybdenum. Stainless steel 316 is mostly used in highly corrosive environments such as chemical handling tanks and tanks near marine environments. Like stainless steel 304, stainless steel 316 has a lower carbon grade, 316L. Lower carbon content is also used for high-temperature applications to prevent sensitization.

Duplex Stainless Steel
This type of stainless steel consists of a combination of austenitic and ferritic metallurgical structures. Austenitic stainless steel is far superior to ferritic in terms of corrosion resistance and mechanical properties. However, it is highly susceptible to stress corrosion cracking. Stress corrosion cracking happens when a crack propagates when the material is subjected to a highly corrosive environment. This can lead to the sudden failure of ductile materials. A ferritic metallurgical structure is resistant to stress corrosion cracking. Combining the ferritic phase with the austenitic phase creates an added resistance to stress corrosion cracking. This is mostly suited for tanks used in environments and process fluids containing chlorides such as water for domestic use.

Maintaining your stainless steel tank

》Check that your gutters are not sagging in spots, allowing water to sit. This stagnant water can breed mosquito larva that can be washed into your tank in the next big rainfall event.

》Inspect and clean your inlet strainer regularly. A clogged or blocked inlet strainer can cause overflowing and flooding, damaging your tank base and voiding warranty.

》Check your tank overflow plumbing to make sure it is securely attached and that it will direct water away from your tank base or into your stormwater.

》Remove any debris or stick and branches from your tank. If you're really keen give it a hose and remove any cob webs and marks to keep it looking great

》Check tank outlets and connections to your house or pump for signs of leaks. If you have an automatic pressure pump, stay by your tank for at least minutes, ensuring no taps are used around your property etc and make sure your pump is not cycling on and off. If so, this means that you must have a slow leak somewhere. For example, if connected to your toilets, one of your toilets may have a slow leak. If this is occurring the pump will use a lot more power, turning on and off unnecessarily.

》Turn on the tap and judge if the pressure is the same as previous inspections. If you visibly notice a reduction in pressure, then there may be a blockage in your system Check your tank base to ensure it has not subsided, cracked or moved. If you notice a lean on your base, immediately drain the water and rectify, especially with slimline water tanks.

》Check the water level to see if it corresponds with recent rainfall. For example, if it rained very recently and your tank is empty you could have a broken in-feed pipe, if it is a wet system. Alternatively, if your water tank never seems to empty and you have a mains water switching system, this could be faulty, so you are only using mains water.

》Do not store any objects on your tanks. The roof is strong and durable but not designed to take pot plants, garden tools or the like store on the top of the tank.

》Check every six months for sediment build up. Our tanks are designed to allow sediment build up to a certain point and the outlet fitting at the bottom of the tank is slightly raised to accommodate this.

》While your checking inside your tank also give it a good smell / or smell the water at an outlet. If the water smells off or is discoloured this mean organic material is finding it way into your tank. Local the source of this, such as leaves in gutters etc and then once corrected you can add a tank purifier solution.
