ASTM A516 Gr.70 Carbon Steel Elliptical Head / Ellipsoidal Dish End For Oil Gas Tanks

ASTM A516 / ASME SA516 Gr.70 Carbon Steel Elliptical Head Ellipsoidal Dish End For Oil Gas Tanks

The elliptical head ( or named ellipsoidal head ) which is a head consisting of two parts: a rotating ellipsoidal sphere and a cylindrical straight section. Elliptical tank head is fabricated to have a certain shape instead of a particular dish radius or knuckle radius. The dish radius is approximately 90% of the diameter and the knuckle radius is approximately 17% of the diameter. 2:1 elliptical flanged and dished heads are ASME compliant.
