Product Show
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.
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.
Compared with other forms of dished head, due to manufacturing difficulties, the hemispherical head is often used in addition to the pressure is higher, larger diameter pressure vessel.
The hemispherical shape is superior to the torispherical shape in strength. Hemispheres are the best shape for mixing vessels such as pharmaceutical manufacturing bowls, because the corner which can cause burning-on of product in a torispherical shape, is therefore eliminated. Our hemispheres are of extra smooth contour, so that agitator blades swipe the surfaces much more effectively.
