Dish head

Short Description:

Dish head refers to a head composed of CR, KR and SF. Due to the abrupt change in the radius of curvature at the junctions of CR and KR, KR and SF, the edge stress is much greater than the film stress caused by internal gray, and its mechanical properties are worse than spherical and oval heads. The dish-shaped head is relatively easy to manufacture because it is shallow and has low requirements on stamping equipment and molds. It is rarely used in force containers, and only used in situation...


  • D0: external head diameter
  • Di: internal head diameter
  • CR: crown radius
  • KR: knuckle radius
  • SF: straight flange height
  • H: height
  • t: wall thickness

    Dish head refers to a head composed of CR, KR and SF. Due to the abrupt change in the radius of curvature at the junctions of CR and KR, KR and SF, the edge stress is much greater than the film stress caused by internal gray, and its mechanical properties are worse than spherical and oval heads.

    The dish-shaped head is relatively easy to manufacture because it is shallow and has low requirements on stamping equipment and molds. It is rarely used in force containers, and only used in situations where the pressure is low and the depth of the head is required to be reduced or the mold is lacking.
