Elliptical head, also known as elliptical head and elliptical head, is a head composed of rotating elliptical spherical surface and cylindrical straight section. The elliptical head with the ratio of the long axis to the short axis of the rotating elliptical spherical generatrix of 2.0 is conventionally called the standard elliptical head. The mechanical performance of elliptical head is only inferior to that of hemispherical head, but superior to that of dished head. Because the depth of the elliptical head is between the hemispherical head and the dished head, the requirements and manufacturing difficulty of the stamping equipment and mold are also between the two, that is, easier than the hemispherical head and more difficult than the dished head. Elliptical head is widely used in medium and low pressure vessels because of its good comprehensive performance. In recent years, the spinning process has brought convenience to manufacture large diameter elliptical heads.
