The expansion of the conical portion is a fan shape, the radius of the fan shape = the length of the conical line (l), and the central angle of the fan shape α = D × 180 / l The dish-shaped head refers to a head consisting of a partial spherical shell, a circular arc and a good edge (cylinder short treatment). Due to the sudden change of the radius of curvature at the junction of the spherical shell and the hem, the hem and the straight edge, the edge stress is much larger than that caused by the inner ash, and the mechanical properties are relatively poor compared with the spherical and elliptical heads. Because the dish-shaped head is lighter and has lower requirements on stamping equipment and molds, it is more convenient to manufacture. It is currently used less for force vessels and is only used where pressure is low and where the depth of the head is required to be reduced or the mold is missing.
