F&d head crown radius
WebE = lowest efficiency of any joint in the head; for hemispherical heads this includes head-to-shell joint; for welded vessels, use the efficiency specified in UW-12. L = inside spherical or crown radius. The value of L for ellipsoidal heads shall be obtained from Table UG-37. P = internal design pressure (see UG-21) r = inside knuckle radius WebJul 16, 2024 · The radius changes constantly throughout the shape. For a 2:1 true ellipsoidal head you use the formula in UG-32 (c), but otherwise 1-4 (c) is used. UG-32 (c) also allows you to manufacture a torispherical head with a knuckle radius of 0.17D and a crown radius of 0.9D, but otherwise calculate and treat it as a 2:1 true ellipsoidal head.
