A516 GR.70 Elliptical Heads Torispherical Heads Tank Caps For Heat Exchanger Parts.
Ellipsoidal Head,Hemispherical Head and Torispherical Head are three types of ASME Pressure Vessel Dished Heads.
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.
