Water tanks provide the ultimate solution to store large capacities of water that will be further used for different purposes, like drinking, cooking, coolant, and so on. These products not only provide a consistent water supply in scarce areas but also ensure zero contamination of the stored water when subjected to different types of environmental conditions. While several tank types are available in the market commissioned for use, the cylindrical water tanks are most popular and can be seen in various fields, from residential to industrial.

Even though these tanks have been in use since decades, several advancements have been made in the construction, coating choice, and other attributes. That’s why knowing more about these revolutionary advancements is crucial to make a better selection of the tank suitable for your purpose. Below we have presented a walkthrough of the tank’s types, benefits, applications, and other related aspects. 

What Are Cylindrical Water Tanks?

From the name itself, one can understand that the cylindrical water tanks are made from a single sheet metal after being processed via calendaring. In this process, the raw sheet metal is passed through multiple heated rollers in a continuous cycle. The pressure and heat exerted make the sheet smoother, compressed, and lighter for further use. Once the sheets are ready, they are welded together at the junction to form the cylindrical-shaped body of the tank. Most often, the enclosures fitted in these tanks are either spherical or elliptical, depending on their purpose and installation preferences. 

What Are The Types Of Cylindrical Water Tanks?

Three types of cylindrical water tanks are prevalent in the market, known for their versatile features and advanced construction techniques. Below we have briefly described each type along with listing their features to help you understand them in detail. 

Corrugated Steel Tanks

CGS or Corrugated Galvanized Steel tanks are made from hot-plunged stirred steel sheets, which are then folded and bolted at the site during installation. Their main purpose is to withstand seismic activities, strong wind flows, and snowfall without causing water leaks or collapsing. It is due to this feature that the corrugated steel tanks are used in areas with drastic environmental conditions, like hilly areas, coastal regions, and earthquake-prone zones. 

Features 

• Classic water tank design 

• Highly durable and can withstand different environmental adversaries

• Impeccable quality 

• Retains the structural stability when exposed to seismic activities

• Comes in various sizes and capacities to cater to versatile requirements

Glass-Fused-To-Steel Tanks

A new, revolutionary concept in water tank manufacturing, the glass-fused-to-steel or glass-lined steel tanks amalgamate the superior strength and durability of steel sheets and the corrosion resistant properties of glass. Usually, the glass layer is present on both exterior and interior walls of the core steel layer to provide impeccable resistance against corrosion caused due to multifarious chemical and physical factors, like atmospheric oxygen, dust, and so on. Usually, the molten glass is fused with the steel sheets at an exceptionally high temperature to form a porcelain-like coating that is chemically inert and can exhibit immense mechanical and physical strength.

Features 

• Excellent durability and structural stability 

• Versatile applications across different industries

• Long lifetime with reduced maintenance needs

• Superior resistance against chemical corrosive factors

• Exceptionally hard and leakproof

Epoxy Coated Tanks

Another category of cylindrical water tanks that has recently got popular is the epoxy coated tanks. Epoxies are nothing but cured, liquid resins that show exceptional resistance against corrosion, mechanical impacts, and leaks. Here, the steel sheets are infused with different types of epoxy resins to form a thick coating layer. The choice of the resin usually depends on the purpose of the tank and the grade of the steel sheet to be used in the tank’s construction. These tanks are superior in terms of durability, stability, corrosion-resistant, and water leak. 

Features 

• Epoxies have lower carbon footprint than other coatings

• Chemically inert and protects the inner steel layer from corrosion

• Withstands different types of mechanical impacts without disturbing the structural stability

• Highly durable and can last for a long time

• An economical choice for commercial and industrial applications

How Cylindrical Water Tanks Are Better For Water Storage?

The cylindrical water tanks have a wider range of benefits than other conventional tank designs. Here are a few advantages to be harnessed:

1. Stability: One of the major advantages of the cylindrical shape of these tanks is the lower position of the center of gravity. Since the point is located closer to the ground, the structural stability remains uncompromised. 

2. Stress distribution: The internal stress generated when stored with large volumes of water gets evenly distributed across the entire tank’s surface. As a result, no high pressure point is created which further enables the tank to store water without causing leaks. 

3. Weatherproof: Since different types of coatings and fusion materials are used to protect the inner steel core layer, the water tanks are weatherproof and can even withstand strong wind velocity, solar heat exposure, and seismic activities. 

4. Easy installation: The cylindrical tanks are made from a single sheet with welded junction. Therefore, they are easy to assemble and install. 

Conclusion 

Over the years, the cylindrical water tanks have evolved in terms of design, material choice, coating technology, and several other attributes. Based on your requirements, you can choose from a wider range of these tanks having varied water storage capacity, corrosion-resistance, durability, and longevity.
