♦ Elliptical 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 torispherical head.
♦ Due to the application of spinning manufacturing process in recent years, the fabrications of the larger diameter elliptical head is also can be realized.
♦ ASME elliptical dished heads are used in the construction of tanks for unfired pressure vessels, such as liquefied petroleum gas and air receivers.
