The elliptical head ( or named ellipsoidal head ) which is a head consisting of two parts: a rotating ellipsoidal sphere and a cylindrical straight section.
Elliptical tank head is fabricated to have a certain shape instead of a particular dish radius or knuckle radius. The dish radius is approximately 90% of the diameter and the knuckle radius is approximately 17% of the diameter. 2:1 elliptical flanged and dished heads are ASME compliant.

What should be considered in the selection of the heads?
1. Customer requirements
2. Requirements of Chemical Process
Conical heads are used for vertical vessels of solid masses to facilitate the flow and discharge of masses. Elliptical head or spherical head for liquid masses.
Stirred pressure vessels should determine the shape of the head according to the shape of the slurry leaf and the flow form of the working mass.
3. According to the pressure. For medium and low pressure pressure vessels, ellipsoidal heads are mostly used. For high pressure and ultra-high pressure pressure vessels, spherical heads are mostly used.
4. Determine from the analysis of considering the stress situation. If the stress transition zone of ellipsoidal head is opened with larger openings and the local stress is too large, spherical head can also be considered.
Elliptical Heads Equipment Machine
The hemispherical head is a head consisting of half a spherical shell and a straight edge (short section of a cylinder). Hemispherical heads has the best mechanical properties and most economical materials used. Hemispherical heads are a popular choice for pressure vessels due to their ideal shape, which divides the pressure in the vessel equally across the head's surface. Also known as hemispherical tank heads or hemispherical dished ends, they're commonly used on liquid and gas storage tanks.
Torispherical head (or flanged and dished head), These heads have a dish with a fixed radius (r1), the size of which depends on the type of torispherical head. The transition between the cylinder and the dish is called the knuckle. The knuckle has a toroidal shape. These heads have a dish with a fixed radius, the size of which depends on the type of torispherical head.
Conical head is a head with conical surface of shell. The characteristic is that it can make the medium pass through with uniform change of speed, and it is easy to unload the viscous liquid and solid particle-containing materials, but the mechanical property is poor, and the discontinuous stress generated by the sudden change of shape at the connection with cylinder or receiver is large.....
