r6155 has it correct that ASME Section VIII, Division 1, paragraph UG-32(c) does indeed allow that a permissible approximation of a 2:1 semi-elliptical head is a torispherical head with a crown radius of 0.9D and a knuckle radius of 0.17D. However, in my opinion, that is a geometric approximation only. The two heads have very different stress results, particularly at the edge of the so-called hemispherical cap big size dish headA.S.M.E. Tank Heads Standard tankheadDished Only Tank Heads. When ordering, specify most important dimensions- outer diameter, crown radius, or depth. Standard and intermediate sizes 12 to 275 inches in diameter can be readily supplies.
