Carbon Steel Half ellipsoidal Head Dish End

 Product Specification:

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.
