The source for hemispherical tank heads for all industries.
We manufacture seamless ASME hemispherical tank heads of many sizes from 6-5/8"OD to 60"ID. For high pressure projects, the advantage of a Hemisphere is that most ASME code calculations require less minimum thickness to hold high pressure than a 2:1 Elliptical head.
