Head (vessel)



From Wikipedia, the free encyclopedia

Steel Pressure Vessel

The end caps on a cylindrically shaped Pressure vessel are commonly

known as heads.

[edit]Head shapes

The shape of the heads used can vary. The most common[1][2][3] head

shapes are:

Hemispherical head

A sphere is the ideal shape for a head, because the pressure in the

vessel is divided equally across the surface of the head. The radius

(r) of the head equals the radius of the cylindrical part of the

vessel.Ellipsoidal head

This is also called a 2:1 elliptical head. The shape of this head is

more economical, because the height of the head is just a quarter

of the diameter. Its radius varies between the major and minor axis.

Torispherical head

These heads have a dish with a fixed radius (r1), the size of which

depends on the type of torispherical head.[4] The transition between

the cylinder and the dish is called the knuckle. The knuckle has atoroidal shape. The most common types of torispherical heads are:

Schematic of a torispherical head

Klöpper head

This is a torispherical head. The dish has a radius that equals the

diameter of the cylinder it is attached to (r 1 = Do). The knuckle has

a radius that equals a tenth of the diameter of the cylinder (

), hence its alternative designation "Decimal head".

Also other sizes are: ,[5](page13) rest of height

(lets say h2) .

Korbbogen head

This is a torispherical head. The radius of the dish is 80% of the

diameter of the cylinder ( ). The radius of the knuckle

is ( ).

Also other sizes are: , rest of height (lets

say h2) . This

shape[6] finds its origin in architecture.[7]

Flat head

This is a head consisting of a toroidal knuckle connecting to a flat

plate. This type of head is typically used for the bottom

of cookware.

Pans typically have a bottom in the shape of a flat head

Diffuser head

This type of head is often found on the bottom of aerosol spray

cans. It is an inverted torispherical head.

This is a cone-shaped head.[edit]
