Description

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.

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.

Applications of Hemispherical Head

STRENGTH Equipments can produce up to 8,000 mm diameter asme hemisphere head depending upon thickness of material and wall thickness up to 50 mm depending upon material and diameter. custom forms and dimensions are also available.

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.
