TYPE OF PRESSURE VESSEL

In industry there is two main type of pressure vessel present generally

CYCLINDRICAL PRESSURE VESSEL
SPHERICAL PRESSURE VESSEL

Some other types of vessels are also available such as Reactors, Distillation Coloumn, Packed Tower etc. these names are given according to their use only.

CYCLINDRICAL PRESSURE VESSEL

Based on the shape (cylinder) of the vessels, they are called as cylindrical pressure vessel. They are further classified into two types,

Horizontal Pressure Vessels
Vertical Pressure Vessels

When the orientation of the vessel is horizontal, that is horizontal pressure vessel. If it is vertical, that is horizontal pressure vessel.

Horizontal vessel

Vertical pressure vessel

Advantages of cylindrical pressure vessels:

It is easier to fabricate.
They are probably cheaper to construct
They pack more efficiently into rectangular structures such as boxes and buildings.

SPHERICAL PRESSURE VESSEL

Based on the shape (spherical) of the vessels, they are called as spherical pressure vessel

SPHERICAL PRESSURE VESSEL

Advantages of spherical pressure vessels:

- For the same internal design pressure, a spherical vessel will require only half the wall thickness as a cylindrical vessel.
- Spherical vessels have the advantage of holding the largest volume per unit surface area of the container.

Note : Pressure vessels have the pressure enclosed by a head that has the pressure acting on the inside of the head. There are a number of different types of heads that can be used:

Ellipsoidal
Torispherical
Hemispherical
Conical
Toriconical

Uses of Pressure Vessel

Pressure vessels are used in a variety of applications in both industry and the private sector. They appear in these sectors as industrial compressed air receivers and domestic hot water storage tanks. Other examples of pressure vessels are diving cylinders, recompression chambers, distillation towers, autoclaves, and many other vessels in mining operations, oil refineries and petrochemical plants, nuclear reactor vessels, submarine and space ship habitats, pneumatic reservoirs, hydraulic reservoirs under pressure, rail vehicle airbrake reservoirs, road vehicle airbrake reservoirs, and storage vessels for liquified gases such as ammonia, chlorine, propane, butane and LPG.
