Type 2: 1 Ellipsoidal Head
1, Type description
2: 1 Semi-Ellipsoidal heads are deeper than a torispherical head and therefore stronger and able to resist greater pressures. These heads are more difficult to form owning to the greater depth required. These are more expensive to form than a torispherical head, but may allow a reduction in material thickness as the strength is greater.
2, Applied Industry: Food, Gas, Petroleum, Chemical, machinery etc.
3, forming range and way
Pls see below Excel sheet
A, Cold Press is for hokkai standard size EHA with inner diameter
Head can be formed with inner diameter ranging from 200-3200mm
