boiler thick wall hemispherical head

Hemispherical Head (Hemi) The hemispherical head has a simple radial geometry: the depth of the head is half the diameter. With a 47" ID, the required wall thickness is 0.2474", about half the thickness of the shell. Because the head is thinner than the shell, a standard code 3:1
