Types of Storage Tanks

As our clients have different storage needs, we offer various solutions. At Savannah Tank, you can order a customized storage tank. But to do that, you must know what types of storage tanks there are and choose the appropriate one.

In reality, there are many classifications of storage tanks. In our comprehensive guide, we will focus on explaining the storage tank types you have at your disposal according to how we build them.

Types of Storage Tanks and How They Are Classified

Almost every product, whether liquid or gas, requires special conditions to be stored in an industrial tank. Consequently, at Savannah Tank, we are dedicated to meeting our client’s needs by allowing you to customize your tank.

We can manufacture different types of storage tanks according to how we build them. They can be divided into many categories according to several factors, such as:

  • Tank’s material of construction
  • Surface finishes
  • Tank’s shape and orientation
  • Atmospheric vs pressurized tanks
  • Bottom configuration options
  • The design of the cover
  • Heating and cooling solutions
  • Internal configurations and accessories

Tank’s material of construction

The basic categorization of storage tank types is based on the materials that comprise them. One of the major benefits of getting our custom storage tanks is that we can use different durable materials to manufacture them. They are proven to be the most long-lasting materials and include:

  • Carbon steel
  • Stainless steel
  • Duplex stainless
  • Inoconels
  • Monels
  • Other nickel alloys

Surface finishes

The surface finishes go hand in hand with the materials we will use to build your customized tank. We have various surface finishes that might help you meet your needs like:

  • Mill finish: this economical option provides a dull-gray smooth and minimally reflective finish.
  • Polished Finish: We can mechanically polish the interior of your tank to a #4 if you need a smoother inside surface finish.
  • Interior and exterior stainless passivation for improved corrosion prevention.
  • Sandblasting for a uniform finish.
  • Interior linings for additional protection from corrosion, rust, and other common damages. Interior linings are also used for potable water storage.
  • Exterior painting for weather resistance and protection against corrosion.
  • Galvanizing or coating the ladders, handrails, and platforms that are often built to access the tank so they can be protected from corrosive environmental contact.

Tank’s shape and orientation

Industrial tanks can come in two different storage tank shapes and orientations. Regarding the shapes, the two most requested industrial tanks are round and rectangular. On the other hand, we can build them in vertical and horizontal orientation, depending on your needs.

So, what are vertical tanks? The name itself explains that vertical tanks are installed vertically. They are typically used by companies that have larger storage needs. Vertical tanks offer stress distribution, stability, and increased efficiency and are typically used for chemical, food, petroleum, and other corrosive and non-intrusive products.

On the other hand, horizontal tanks are generally smaller than the vertical ones. In order to maintain structural integrity, it’s common practice to limit their length to no more than six times their diameter.

One of the biggest benefits of horizontal tanks is easy mobility and transportation. But what are horizontal tanks used for? Horizontal tanks are often used in situations where there may be height restrictions.

Atmospheric vs pressurized tanks

Another important distinction of storage tanks is between atmospheric tanks and pressurized tanks. Depending on the product you are planning on storing in the tank, we can manufacture both types.

If the product can be stored under ambient conditions, atmospheric tanks are the obvious choice. However, for more delicate substances that must be stored in a stabilized environment under pressure, we can manufacture pressurized tanks for you.

Bottom configuration options

The bottom configuration of your storage tank is also important. We offer four options: flat, conical sloped bottom, and dished.

The design of the cover

When it comes to the different types of storage tanks, you should know that they can have several cover designs. At Savannah Tank, we offer various cover designs like:

  • Open top
  • Flat top
  • Conical top
  • Dished top
  • Bolted / removable top
  • Agitator bridges and mounting flanges
  • Hinged access doors and hatches

What are floating roof tanks?

Floating roof tanks are a special type generally used for storing large quantities of petroleum substances. They have a cylindrical steel shell and a roof that floats on the liquid’s surface inside the tank. The roof doesn’t cover the liquid entirely. Instead, there is a small border rim space that isn’t covered.

What are flexible tanks?

A non-traditional way of storing liquids is using flexible tanks. We don’t produce them because they are not durable and don’t last long. Yet, they offer advantages such as quick setup, folding ability, and lightweight material.

Heating and cooling solutions

Each substance requires a specific temperature range for storage. That’s why we offer various heating and cooling solutions for your tank. Depending on your requirements, we can install dimple, half-pipe, or conventional jackets, internal pipe coils, and insulation supports.

Configurations and accessories

The types of storage tanks can be divided according to their internal configurations and available accessories. We offer different components, with the most popular being baffles, dip tubes, sparger pipes, and support rings.

Per your request, we can also add exterior accessories to the storage tank to make it more practical. For example, we can build ladders, platforms, stairs, wind deflectors, handrails, and similar accessories to enable operators to access different levels of the tank.
