7 reasons why stainless steel water tanks are perfect for Industries.

A water storage tank serves as a reservoir for clean, filtered water until it's ready for consumption. Depending on the system, atmospheric tanks necessitate a booster pump to maintain water pressure, while pressurized tanks are designed to expel water on demand. Water tanks find prominent use in municipal enterprises, large-scale industrial premises, and a number of other industries.

Stainless steel water tanks have gained popularity over potentially harmful plastic units due to their durability and safety. These pre-fabricated tanks are available in various sizes, providing flexibility to suit different needs and industries. Constructed with bolt-together components, stainless steel water tanks, especially in larger sizes, stand as a suitable choice for efficient water storage.

To ensure water purity and longevity, steel tanks designed for storing potable water feature a protective liner, preventing contamination and rust in the metal tank's zinc alloys. This liner acts as a barrier, maintaining the cleanliness and freshness of the stored water.

Before you we dive into the 7 reasons, you must understand that the different grads of stainless steel are used for water tank based on your industry needs. You should identify which grade material is appropriate for your industry needs. 

Different Grades Of Stainless Steel Used For Water Tanks in Various Industries

Stainless steel grade 304 contains nickel, manganese, and chromium. It is the most commonly chosen stainless steel grade due to its corrosion resistance across various applications. Additionally, it is a cost-effective stainless steel with a ductile structure, making it suitable for manufacturing a variety of products.

Stainless steel grade 304L, on the other hand, has a comparatively low carbon content to mitigate the risk of sensitization, a process involving the reaction of carbon atoms and chromium under high temperatures.

Furthermore, stainless steel grades 316 and 316L provide alternative options for manufacturing corrosion-resistant products.


Reasons For Using Stainless Steel Water Tanks For Your Industrial Purpose

Available in different shapes, stainless steel tanks can hold gallons of water.

1. Resistant To Corrosion and Rust

Stainless steel water tanks are resistant to corrosion in most environments where tool steel and carbon steel corrode. This metal is corrosion-resistant because of the formation of a thin oxide layer on its surface. It is also known as the passive layer because it makes the surface of the metal electrochemically passive in any corrosion environment. 

The presence of chromium results in the development of this passive layer. There should be 10.5% chromium in the stainless steel. A higher chromium content means stronger rust-resistant capability. Other elements like manganese and nickel improve this potential.

2. Stainless Steel Tanks Suitable For Any Situation

Food, dairy, beverage, medicine, and several other manufacturing units invest in stainless steel tanks for their industrial purposes. The best fact is that a stainless steel water tank can endure different environments and situations. You can even install it in coastal areas.

Although stainless steel tanks are mainly used for water storage, you may use them for holding other high-temperature liquids. The melting point of the metal is around 1,500 C. So, there is no risk of getting this metal damaged. 

Temperature conditions and worst weather will not cause cracks to your stainless steel tanks. These water storage systems are also resistant to harmful UV rays. Thus, water stored in the tank will be safe.

3. Maintain Hygiene Of Water

Some people invest in concrete storage tanks due to their cost-effectiveness. But, they are not conscious that these concrete tanks are not the hygienic solution. There is a risk of chemical leakage, mold growth, and bacterial issues in the concrete tank. As concrete tanks are porous, they can leach calcium. As a result, your water will get contaminated. However, you can avoid this issue by installing stainless steel water tanks. The passive film is highly stable and maintains inertness in water.

As the stainless steel tank is non-porous, it leads to no leakage problems. Hygiene is important, especially for drinking water. That is why buying a stainless steel water tank is a good decision. 


4. An Eco-Friendly and Aesthetically Pleasing Solution

Stainless steel is a safe, eco-friendly metal alloy. Manufacturers have started implementing more advanced techniques for producing this material. A stainless steel tank is made from 60% recycled material. 

Another reason for choosing stainless steel water tanks is their aesthetics. These metal tanks are more appealing than concrete and plastic storage systems. The latter ones appear dull after using them for a couple of years. But, stainless steel units look new even if you have used them for years.

5. Great for Mobility

If it is a concrete water storage unit, you need to install it in a particular place. Until you have replaced it, the tank will remain fixed at a spot. However, in some cases, you may want to move the storage system to a new place. That is why stainless steel water tanks are better than these traditional concrete tanks.

Using a forklift or other industrial equipment, you can transfer the stainless steel tank to another spot. You will be able to avoid the cost of purchasing a new unit.  

6. Low Maintenance, Cost-Saving Solution

Stainless steel tanks are low-maintenance storage solutions designed to provide trouble-free performance for years. It is safe to store drinking water in these tanks. However, to make the corrosion-free finish long-lasting, you should clean the tanks using warm water and mild detergent. Bleaching agents and acids are not safe for your stainless steel tanks.

Besides, dirty water may leave residues inside the tank. If you do not clean the tank, it gets stained. Choose the right cleaning agent to treat the stainless steel surface. 

7. Good for Insulating properties

Stainless steel water tanks have different variations- single-walled and double-walled. Double-walled metal tanks are best for their insulating capabilities. If you want to install the water tank in cold regions, insulated stainless steel storage models are the right choice. 

The best metal tanks have an insulated layer on the bottom, sides, and top. So, your water will not get frozen even in sub-zero conditions. Due to the insulation capabilities of the tank, you do not need to use electricity to maintain the temperature of water.

Industries that need to store temperature-sensitive liquids also invest in stainless steel tanks.
