Hemispherical Heads (Crown & Petal Construction)
Hemispherical Head (also called hemispherical tank heads or hemispherical dish ends) is widely applied to make pressure tanks to store liquids and gasses. Our hemispherical head is often made with carbon steel, stainless steel, austenitic and non-ferritic metals that can be cold worked. Hemispherical is the ideal shape for the development of a hemispherical dish end because the pressure in the vessel is divided equally across the surface of the head.
The radius (Ri) of the head equals the radius of the cylindrical part of the vessel. This type of hemispherical tank heads or hemispherical dish ends is made in the most popular sizes and thicknesses.

Ellipsoidal Heads (Seamless Cold Forming Construction)
Ellipsoidal head (also called elliptical head or elliptical dish end) is usually made with Carbon steel, stainless steel, austenitic and non-ferritic metals that can be cold worked. The shape of this ellipsoidal head is more economical because the height of the head is just a fraction of the diameter. The elliptical dish end radius varies between the major and minor axis usually with the ratio is 2:1. The elliptical tank head is the economical solution for medium pressure tanks due to the reduced metal thickness requirement.
The ellipsoidal head has good mechanical properties better than the tori spherical head. ASME elliptical dished heads are used in the construction of tanks for unfired pressure vessels, such as liquefied petroleum gas and air receivers.
