Storage Tanks Roof Types

These tanks are usually large dome roof tanks that are insulated to keep the stored product cool.

Storage tanks roof types.

Keeping the product cool allows it to be stored at or near atmospheric pressure. Dome roof storage tank has the advantages of simple manufacturing and low cost thus it is widely used in various of fields. An internal floating roof tank has both a permanently affixed roof and a roof that floats inside the tank on the liquid surface contact deck or is supported on pontoons several inches above the liquid surface noncontact deck. Tanks initially constructed with both a fixed roof and an internal floating roof may be of either type.

Floating roof tanks can be divided into two types. Internal floating roof tanks are used for liquids that have lower melting points like gasoline and ethanol. Dish roof storage tank. Dome roof tank is a kind of steel container with a spherical roof and a cylinder tank body.

As the name suggests the floating roof tank consists of a floating roof which falls or rises according to the level of oil in the tank. The dome is designed to accommodate the positive pressure in the tank. Refrigerated storage tanks store liquefied hydrocarbon gases like propane and butane. These are used for liquids at higher pressure.

These are fixed roof storage tank with dish shape head. To prevent the build up of vapor inside the tank the floating roof in this type of tanks has been incorporated as a safety feature. Types of industrial oil storage tanks floating roof tank.
