ASME SA516 Gr.70 Carbon Steel Elliptical Tank Head / Ellipsoid Dish End For Pressure Vessel
Ellipsoidal head (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 common one is SA516 Gr.70 and 304,316L and so on. Ellipsoidal head is the main pressure-bearing part of the pressure vessel to close the end of the vessel for sealing, it is welded to the vessel shell.
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.
