The mechanical properties of elliptical heads are only inferior to hemispherical heads but superior to dished heads. As the depth of the elliptical head is between the hemispherical head and dished head, the requirements for stamping equipment and mold and manufacturing difficulty are also between them, that is, it is easier than hemispherical head and more difficult than dished head.
In recent years, the spinning manufacturing process has brought convenience for manufacturing large-diameter elliptical heads, which are widely used in medium and low-pressure vessels due to their good comprehensive performance.
Elliptical heads are widely used in petroleum, electronics, chemical, pharmaceutical, textile, food, machinery, construction, nuclear power, aerospace, military, and other industries.
