Diameter (D) mm. 3 mins SASINTL Dish Head FormingThe shape of this ellipsoidal head is more economical because the height of the head is just a fraction of the diameter. The elliptical dish end radius varies between the major and minor axis usually with the ratio is 2:1. The elliptical tank head is the economical solution for medium pressure tanks due to the reduced metal thickness requirement.
Dished end , also called dished head or tank head , is an important pressure element for pressure vessels and boilers.The dished end is usually used at both ends of the pressure vessel and welded with the cylinder. According to the different geometric shapes, it can be divided into elliptical tank head , torispherical end , hemispherical dish end , spherical end , 2 mins Pressure Vessels, Spherical Pressure vessels (Pressure Pressure Vessel ellipsoidal dished end HeadShape of a Pressure Vessel . Pressure vessels can theoretically be almost any shape, but shapes made of sections of spheres, cylinders, and cones are usually employed. A common design is a cylinder with end caps called heads . Head shapes are frequently either hemispherical or dished (torispherical). When to use a dished pressure vessel head?When to use a dished pressure vessel head?Used in high pressure vessels where the vessel is thickness is also high. Not applicable where small space is required. Widely used as bottom heads. It facilitate the removal or draining of the material. Not used in the Dished Head of pressure vessel because this worked under lower pressure.Different Types of Pressure Vessel Head - The Engineering Concepts
Hemispherical 2:1 Elliptical Torispherical Conical Flat Hemispherical, half-sphere is the ideal shape for a vessel head. This is because forces are spread out equally across the head. The radius of the hemisphere is constant as opposed to an elliptical head. The radius is equal the the radius of the shell that it attached to.

The radius of the dish is 80% of the diameter of the cylinder (CR = 0.8 x D 0 .).

Vessel heads are very varied used in candleholders to pipe end -pieces or pressure vessels in equipment construction. We manufacture a wide range of vessel heads to works standards, both for construction purposes and as dished vessel heads in the form of torispherical heads , elliptical heads and caps for pressure applications.
Ellipsoidal Head , Hemispherical Head , and Torispherical Head are three types of ASME Pressure Vessel Dished Heads . Hemispherical Head (also called hemispherical tank heads or hemispherical dish ends) is widely applied to make pressure tanks to store liquids. PETROL STEEL CO., LTD is a leading supplier specialized in steelhead plates in China. Ellipsoidal Head - Industrial Autoclave, Storage Tank Pressure Vessel ellipsoidal dished end HeadThe shape of this ellipsoidal head is more economical, because the height of the head is just a fraction of the diameter.

The ASME VIII-1 calculated design pressure for the cylinder is 420 psi. 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. The wall thickness is varied to meet the 420 Pressure Vessel ellipsoidal dished end Head
