ASME SA516 Gr. 70 ,SA-516-70N Dished Elliptical Head End Caps
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.
A516 Gr70 not only has very high strength, but also has very good toughness, wear resistance, fatigue resistance, impact resistance, easy welding processing and cold forming properties.
Oval heads (also called elliptical heads or elliptical heads) are typically made from carbon steel, stainless steel, austenitic and cold-worked metals. This oval head shape is more economical because the height of the head is only a fraction of the diameter.
