1, Description
Hemispherical heads allow more pressure than any other head. However, the hemispherical head is the most expensive to form, as they consists of a number of petals or gores. The number of which depends on the size of the head and the thickness of the plate to be used. The depth of the head is half of the diameter.
Hemispherical heads are also used in architectural applications by joining two hemispheres together to form a spherical ball. Other common applications are for stainless steel cooking kettles with steam jackets.
