Hemispherical Head (also called hemispherical tank heads or hemispherical dish ends) is widely applied to make pressure tanks to storage liquids and gasses.
Our asme hemispherical head is often made with carbon steel, stainless steel, austenitic and non ferritic metals that can be cold worked.
The smaller diameter of the hemispherical head can be the overall compression molding, but the larger diameter because of its large depth, the overall compression is difficult, it is necessary to use a number of the same sizes of the trapezoidal ball and the top of the center of a round spherical plate ball crown made of welding.

The hemispherical head can be manufactured according to customer's requirement, drawing, design or samples.
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.
Our factory mainly produce diameter of 89mm - 12000 carbon steel ball, steel hemisphere, stainless steel hollow ball, hollow steel ball, hollow metal ball, bearing steel ball, stainless steel ball, precision grade G10-G2000, for bearing, stainless steel bearings, hardware, wheels, instrumentation, rail, polishing, chemicals and solid grinding.
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.
