Carbon steel Ellipsoidal head

The shape of this head is more economical, because the height of the head is just a fraction of the diameter. Its radius varies between the major and minor axis; usually the ratio is 2:1.

Cold press forming is for standardization and mass production, it can be formed with inner diameter from 200mm to 3200mm(50mm pitch up to 2000mm, and 100mm pitch for above 2000mm), and with plates thickness of up to 28mm using the 6000ton that Hokkai developed.

Cold Spinning forming is for non standard larger Dished Heads production, this forming way can be achieved with inner diameter from 750mm-9000mm, and with plates thickness up to 45mm .
