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.

Vessel dished ends are mostly used in storage or pressure vessels in industry. These ends, which in upright vessels are the bottom and the top, use less space than a hemisphere (which is the ideal form for pressure containments) while requiring only a slightly thicker wall.

Torispherical Head Package & Delivery
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.
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.
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.....
