There many shapes and sizes of storage tanks. Their choice depends on type of product to be stored, fire potential of product and amount of product to be stored.

In this article, we will discuss the most common type of vessels found in process facilities.

Horizontal Pressure Tank -Bullet Tank

Bullet tanks are usually shop fabricated vessels used to store products under high pressure. The heads of these vessels are either elliptical or hemispherical. The hemispherical heads are used when higher pressures are required.

Horton Sphere Pressure Storage Tank

This is a spherical tank, used to store large quantities of liquids and gases under high pressure. Often there is limited road access to a plant site. So it is easier to erect a Horton Sphere in the field instead of prefabricating it somewhere else and transporting it to site.
