Large Diameter 5500mm 3000mm AS516GR70 Elliptical Dish Head for Pressure Vessel

Large Diameter 5500mm 3000mm AS516GR70 Elliptical Dish Head for Pressure Vessel 

The Elliptical head is the most common type of heads. It can be seen in various equipment such as pressure vessels, storage tanks, heat exchangers, Planatery Mixer Machine etc. It has relatively high pressure tolerance and low molding difficulty.

Specification

Elliptical head:

Elliptical head (also called hemispherical tank heads or hemispherical dish ends) is widely applied to make pressure tanks to storage liquids and gases. The hemispherical head is often made with carbon steel, stainless steel, austenitic and non ferritic metals that can be cold worked. Hemispherical is the ideal shape for development of hemispherical dish end, because the pressure in the vessel is divided equally across the surface of the head. The radius (Ri) of the head equals the radius of the cylindrical part of the vessel. This type of hemispherical tank heads or hemispherical dish ends are made in most popular sizes and thicknesses.

The stainless tank head is one of the key pressure-bearing components and core structures of a planetary mixer.  It is not only an important part of the pot body but also a crucial element in ensuring the safe, efficient, and stable operation of the equipment under mixing, heating/cooling, and vacuum conditions. Its design, materials, and manufacturing process directly affect the overall performance, service life, and hygienic safety standards of the product.
