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

Jan 15, 2017 · 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 42-48 inches Carbon Steel 2:1 ASME Semi-Elliptical Tankheads42-48 inches Carbon Steel 2:1 ASME Semi-Elliptical Tankheads. HANSON'S 2:1 SEMI-ELLIPTICAL TANK HEADS:We manufacture our own carbon and stainless steel tank heads from 12" to ten feet in diameter, and keep hundreds in stock to ensure the fastest possible deliveries on finished vessels. We even supply tank heads to other tank fabricators on a regular basis.
