Comparison Between Head Types: Hemi, SE, F&D and Flat
Four commonly used head types on vessels are Hemispherical (Hemi), Semi Elliptical (SE), Flanged and Dished (F&D) and Flat. For this article, each of the four heads is attached to the cylinder, with diameters matching on the ID.

Custom Tank Heads & Vessel Heads - Brighton Tru-Edge
Reversed flanged and dished tank heads are comprised of both a concave dish radius and a knuckle radius. They are often used on the ends of vessels that face against a plane surface, such as steel vessels on concrete slabs. These tank heads offer the advantage of a load-bearing surface as well as the additional strength from dishing.
