The term “storage tank” has a remarkably broad definition. While it sounds simple enough, a storage tank will vary from person to person and industry to industry. Custom fabricated storage tanks can be designed and built to contain organic liquids, non-organic liquids, vapors, or solids. These custom tanks are specifically designed and built with a customer’s need and usage in mind. Industries where storage tanks can be found are typically industries consuming or producing good, liquids, and or vapors. Industries like petroleum either in producing or manufacturing petroleum, chemical engineering and or manufacturing, and the agriculture industry for bulk storage.

The use of the storage tank and what it will contain will determine the type of tank required.
This means, that the quantity of heat transferred from warmer surroundings to the liquid in the sphere.
Cylindrical Storage Tanks – Cylinders are widely used for storage due to their being less expensive to produce than spheres. However, cylinders are not as strong as spheres due to the weak point at each end. Hemispherical or rounded ends being fitted reduce this weakness. If the whole cylinder is manufactured from thicker material than a comparable spherical vessel of similar capacity, storage pressure can be similar to that of a sphere.
Both tanks, fixed roof or internal floating are used to reduce steam losses and preserve the stored fluid. A typical external floating roof tank consists of an open-topped cylindrical steel shell equipped with a roof that floats on the surface of the stored liquid, rising and falling with the liquid level. External floating roof tanks are equipped with a rim seal system, which is attached to the roof perimeter and contacts the tank wall. The rim seal system slides against the tank wall as the roof is raised and lowered.
Storage tanks can be fabricated from several different materials. They type you choose for your tank will depend on how you will use the tank, the material you plan to store and the conditions in which you will store it.
Stainless steel also has a long lifespan that makes it quite affordable. The cost of ownership is lower than a concrete or bolted steel tanks. Stainless steel tanks require les maintenance and will last much longer. Additionally, Stainless steel tanks are an eco-friendly storage option. Stainless steel is completely recyclable once a tank is taken out of service, and more than half of new stainless steel being used today is made from previously recycled material.
Carbon Steel – Carbon steel has higher carbon content than stainless steel. Because of the larger amounts of carbon, tanks created with this material offer better heat distribution. This is useful for customers who plan on heating the contents of their tank. Carbon steel is also wear resistant, which is an important quality in an industrial tank, as well as malleable. The higher carbon content makes the steel harder and stronger than other steels. Tanks made with carbon steel tend to be more affordable. A tank made with carbon steel will require less materials than a stainless steel tank, while the materials are less expensive than those used for exotic metal tanks. Carbon steel is usually preferred in situations where the tank will be stored indoors or under cover. Since carbon steel is more prone to rusting, it is best to place these tanks indoors.
