Definition

Defines the types of access (or cover) to a tank that may be specified.Note that covers are generally specified for rectangular tanks. For cylindrical tanks, access will normally be via a manhole.

An arbitrary open tank type.

An open container that breaks the hydraulic pressure in a distribution system, typically located between the fluid reservoir and the fluid supply points. A typical break pressure tank allows the flow to discharge into the atmosphere, thereby reducing its hydrostatic pressure to zero.

A closed container used in a closed fluid distribution system to mitigate the effects of thermal expansion or water hammer. The tank is typically constructed with a diaphragm dividing the tank into two sections, with fluid on one side of the diaphragm and air on the other. One example application is when connected to the primary circuit of a hot water system to accommodate the increase in volume of the water when it is heated.

An open tank that is used for both storage and thermal expansion. A typical example is a tank used to store make-up water at ambient pressure for supply to a hot water system, simultaneously accommodating increases in volume of the water when heated.

An open container for environmental protection and storage of chemical products.

A closed container used for storing fluids or gases at a pressure different from the ambient pressure. A pressure vessel is typically rated by an authority having jurisdiction for the operational pressure.

Common attributes of a tank type.

An open or closed container used for storing a fluid at ambient pressure and from which it can be supplied to the fluid distribution system. There are many examples of storage tanks, such as potable water storage tanks, fuel storage tanks, etc.

A tank is a vessel or container in which a fluid or gas is stored for later use.

An arbitrary closed tank type.
