Torispherical head (or flanged and dished head) [ edit] These heads have a dish with a fixed radius (r1), the size of which depends on the type of torispherical head. [3] The transition between the cylinder and the dish is called the knuckle. The knuckle has a toroidal shape. The most common types of torispherical heads are: See more A head is one of the end caps on a cylindrically shaped pressure vessel. See more Vessel dished ends are mostly used in storage or pressure vessels in industry.

"WebFor pressures over 10 bar, ellipsoidal heads are often used. In cross-section, the head resembles an ellipse, its radius varying continuously. This results in a smooth transition between the dome and the cylindrical part of the vessel. Ellipsodial heads are deeper than comparable torispherical heads.
