Description

ASTM A240 321 Stainless Steel 2:1 Ellipsoidal Head / Dish End For Pressure Vessel

Ellipsoidal head is also called elliptical head or elliptical dish end. 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.
