(also called elliptical head or elliptical dish end) is usually made with Carbon steel, stainless steel, austenitic and 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 pressure tanks due to the reduced metal thickness requirement.

Hot Stamping

Cold Spinning

  STRENGTH Equipments can produce up to 26,000 mm diameter asme elliptical head depending upon thickness of material and wall thickness up to 200 mm depending upon material and diameter. Custom forms and dimensions on request.

  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.
