2:1 Elliptical Vs 2:1 Torispherical Heads - Boiler and hemispherical cap big size dish 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 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.

Mechanical Engineering Why do we use a Hemispehrical hemispherical cap big size dish head

There are two kinds of heads used in used in pressure vessels, namely flathead and dished head. In dished head we have several types, such as Torispherical, ellipsoid and Hemispherical. Dish heads have inherent resistance to deformation, Below hemispherical cap big size dish headPressure Vessel Tank HeadsHemispherical Heads PRESCOR manufactures 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.Pressure Vessel Tank HeadsHemispherical Heads PRESCOR manufactures seamless ASME hemispherical tank heads of many sizes from 6-5 8"OD to 60"ID.
