Generally, elliptical dished heads

Are approximately as strong as seamless cylindrical shell having the corresponding I.D and O.D

Resist half the pressure rating compared to hemi spherical head provided on the cylindrical shell of the same thickness and diameter

All of these

Are manufactured on 2:1 ratio of major to minor axis and is recommended to be used for pressure vessels operating above a pressure of 1.5 MN/m²
