The shape of the heads used can vary. The most common head shapes are: Hemispherical head A sphere is the ideal shape for a head, because the stresses are distributed evenly through the material of the head. The radius (r) of the head equals the radius of the cylindrical part of the vessel. Ellipsoidal head … 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. These ends, which in upright vessels are the bottom and the top, use less space than a See more Heat treatment may be required after cold forming, but not for heads formed by hot forming. See more The manufacturing of such an end is easier than that of a hemisphere. The starting material is first pressed to a radius r1 and then curled at the edge creating the second radius r2.
