Da ≤ 4000 mm and nominal wall thickness s ≤ 50 mm.
| Specification |
|---|
| r1 = Da |
| r2 = 0,1 * Da |
| Da = Do = D |
| h1 ≥ 3,5 * s |
| h2 = 0,1935 * Da - 0,455 * s |
| h3 = h1 + h2 |
| V ≈ 0,1 * (Da-2 * s)3 without flange height h1 |
| Aa ≈ 0,99 * Da2 without flange height h1 |
| Ai ≈ 0,99 * (Da - 2 * s)2 without flange height h1 |
h: height | r: radius | Da: outer-Ø | s: wall thickness | V: volume | Aa/ Ai: external and/or internal surface
Tolerances
Tolerance limits for the internal height h3
- upper deviation: + 0.015 * Da or 10 mm (the larger value is permissible in each case)
- lower deviation: 0
