The production of dished heads for tank and pressure vessels can be achieved through cold forming or hot forming. For both options, there is deep drawing and the two-step process of dishing and flanging.
The deep drawing method is most suitable for repetitive pressed heads; the tools are tuned for each size, so the operating costs are calculated on a serial production of heads. The choice of cold or hot processing then depends on the material type, geometric dimensions, and equipment cost.
The dishing and flanging method can be used on a variety of plate qualities, thicknesses, and diameters. Because of this wide capacity range, the process requires an experienced operator to achieve the best performance from the process line.
Faccin Group has developed equipment that manufactures heads from 2 to 80 mm using cold forming, in 360-Mpa material with elliptical shape. Using hot forming, it has reached a plate thickness of 210 mm for a 5,000-mm-dia. elliptical shape being used for secondary pressure vessels in nuclear plants.
The company recently designed and manufactured a CNC flanging machine without a center hole for flanging titanium heads of various possible diameters using hot forming. For the same customer, it is building a new dishing press that can use cold and hot forming, equipped with hydraulics that cut energy consumption up to 50%, increasing the overall speed 12%.
