2:1 Elliptical Vs 2:1 Torispherical Heads - Boiler and

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
