storage tank
A tank is a container, usually for liquids, sometimes for gases. Tanks can be many shapes, but large tanks tend to be cylindrical, or to have rounded corners, to easier withstand hydraulic pressure of contained liquid. See Tank (disambiguation)#Containers for more information about types of containers called tanks.
A large tank is sometimes mounted on a lorry or on an articulated lorry trailer, which is then called a tanker. Heat storage tank for increased operating flexibility from TARM USA.
Special features
Since most liquids can spill, evaporate, or seep through even the tiniest opening, special consideration must made for their safe and secure handling.
Floating roof
Some storage tanks need a floating roof in addition to the fixed roof of the structure. This floating roof rises and falls with the liquid level inside the tank, thereby eliminating the vapor zone. Floating roofs are considered a safety requirement as well as a pollution prevention measure for many industries, including petroleum refining.
