Elliptical heads 1,9:1
|r1||=||di / 1,16|
|r2||=||di / 5,39|
|h1||> =||3,5||*||s||(or as desired)|
|h2||=||di / 3,8|
(r1: Dishradius | r2: Knuckle radius | da: Outer diameter | di = inner head diameter | h1: straight flange height | h2: Depth of dishing | h3: total internal head height | s: Wall thickness)
Tolerances for height, scope, out-of-roundness, wall thickness, etc. are in accordance with DIN 28013 – Elliptical heads.
- <= 3300 mm
- s <= 18 mm
