Storage tanks form an integral part of industries like petroleum manufacturing, agriculture industry, chemical engineering units, etc.

The requirements of storage tanks vary from industry to industry. Hence, custom fabricated storage tanks can be utilized to meet the customer’s needs. They can be used to store both organic and inorganic liquids.

Read ahead to learn about different kinds of storage tanks and the materials used to make them.

Types of Fabricated Storage Tanks:

  1. Spherical storage tanks: The spherical shape helps in the even distribution of pressure on the surface. This is accomplished both internally and externally leaving no susceptible points. Spherical tanks possess a small surface area to volume ratio. This causes an inflow of heat from the surroundings to the liquid in the tank. These tanks are ideal for storing high-pressure liquids. The only limitation they have is the exorbitant cost when compared to cylindrical vessels.
  2. Cylindrical Storage Tanks: They are cylindrical in shape. The upper and lower hemispheres give them tensile strength. However, they have more weak points than the spherical tanks. Nevertheless, they have a low manufacturing cost and can be used for storing liquids that do not generate much pressure.
  3. Fixed Roof Storage Tanks: These tanks are formed from a cylindrical steel shell having a dome/cone-shaped roof. The two are fixed permanently through the welding process. These can be utilized to store chemicals both in liquid or vapour form. They are the least expensive.
  4. Floating Roof Tanks: Just opposite to the fixed roof tanks, these storage tanks possess a floating roof. These are used when the chemical has to be stored near atmospheric pressure. The floating roof provides a significant gap between the tank ceiling and the product. Thus, the chemical can be exposed to the external environment. It helps to reduce the steam losses which in turn preserves the stored liquid.

The material used for the construction of the storage tank:

The tank should be selected on the quality of the material used as well as the nature of the chemical to be stored.

  • Stainless Steel – Steel offers high tensile strength and is quite durable. Moreover, it is resistant to dust, corrosion, UV light, etc. They have a longer lifespan than conventional steam. They are leak-free and distribute the chemical stress equally on the surfaces. They require low maintenance and are eco-friendly due to their recyclability. They can be customized by adding more internal layers to store food chemicals, fertilizers or petroleum-based products.
  • Carbon Steel: The difference between stainless steel and carbon steel is about the quantity of carbon. The more the carbon content, the better the heat distribution. Carbon steel is wear-and-tear resistant. The carbon steel storage tanks are comparatively cheaper than other tanks. They are preferred for indoor locations.
