1.1 Types of Atmospheric Storage Tank Roofs
The most common type of atmospheric storage tank is the fixed cone roof tank,
up to 300 ft (91.5 m) in diameter & 64 ft (19.5 m) in height (larger diameter tanks have been built, mostly outside the U.S.)
These roofs are normally supported by internal structural but can be fully self-supporting in smaller diameters (typically, 60 ft [3 m] diameter or less).

1.1.1 Types of Atmospheric Storage Tank Roofs
The umbrella roof has radially-arched segmental plates with integral framing support members (usually withoutinternal support columns).
In the steel dome roof tank, the roof plates are usually formed with curved segments joined to be self-supporting.

1.1.4 Types of Atmospheric Storage Tank Roofs
The floating-roof tank is designed to minimize filling and breathing losses by eliminating or minimizing the vapor space above the stored liquid. The shell and bottom of this type of tank are similar to those of the fixed roof tanks, but in this case, the roof is designed to float on the surface of the stored liquid. Older styles of floating roofs include single steel deck details without annular pontoons. Such roofs have no reserve buoyancy andare susceptible to sinking in service.

1.1.5 Types of Atmospheric Storage Tank Roofs
Annular-pontoon and double-deck Some floating-roof tanks havefixed aluminium geodesic dome roofs installed on top of the tank shell to reduce product vapor loss or to eliminate the need to drain rainwater from the roof. These are considered internal floating roofs is a tank with a fixed steel cone roof over a floating roof.

Tanks that have cylindrical shells and cone
or dome roofs are typically used for
pressures less than about 5 lbf/in.2
(34.5 kPa) gauge. Tank bottoms may be
flat or have a shape similar to the roof.
Hold-down anchorage of the shell is
generally required.
Vapor Dome Roof
Types of Storage TanksLOW PRESSURE STORAGE TANKS
Low-pressure storage tanks are those designed to operate with pressures in
their gas or vapor spaces exceeding the 2.5 lbf/in.2 (18 kPa) gauge permissible
in API Std 650, but not exceeding the 15 lbf/in.2 (103 kPa) gauge maximum
limitation of API Std 620.

1.2.2 Types of Low Pressure Storage Tank Roofs
For pressures above about 5 lbf/in.2Gauge (34.5 kPa), hemispheroid, spheroid, and noded spheroid tank types are commonly used. Tanks for this application are now typically constructed as spheres. Such tanks are designed to withstand the vapor pressure that may be developedwithin a tank having no devices or means to change or relieve the internal volume. Plain Hemispheroids
