2:1 Elliptical Vs 2:1 Torispherical Heads - Boiler and torispherical ellipsoidal head

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 ASME Head vessel - KAKA Engineering, we're driving the futureEllipsoidal head knuckle radius 0.17D torispherical knuckle 0.06D torispherical ellipsoidal head Calculating Tank Volumeconical, ellipsoidal , guppy, spherical, or torispherical heads where the fluid height, h, is measured from the tank bottom to the fluid surface, see Figs. 1 and 2.
