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.
Elliptical Heads Details
D0 = Outer diameter
Di = Inner diameter
SF = Stepped-edge height
DH = Dish height
THi = Total height innen
KR = Dish radius
CR = Wall thickness
