Mild steel stainless steel hemispheres dish head end cap

Hemispherical Tank Head (also called hemispherical  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. 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 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.
