What is elliptical head
Elliptical head, also known as elliptical head oval head, oval head, is composed of two parts rotating ellipsoidal and cylindrical straight segments of the head. Ellipsoidal bus than the rotation length, minor axis of 2.0 elliptical head, known as the standard oval head customary. Mechanical properties of elliptical head behind hemispherical head, but better than the dished head. Because between the hemispherical and dished head depth is between elliptical head, stamping equipment and tooling requirements are also difficult to manufacture in between, that is easier than hemispherical head, dished head than difficult.
Elliptical head due to better overall performance, is widely used in low-pressure containers. In recent years, due to the spin suppress the removal process for the manufacture of large-diameter oval head to bring the convenience.
