torispherical head DIN 28011KB.
torispherical head DIN 28011
DIN 28011
DIN 28011 applies for one-piece heads with and without welding seam with an external diameter
of Da ≤ 4000 mm and nominal wall thickness of 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 border height h1 |
| Aa ~ 0,99 * Da2 without border height h1 |
| Ai ~ 0,99 * (Da - 2 * s)2 without border height h1 |
h: Height | r: Radius | Da: outside-Ø | s: Wall thickness | V: Volume | Aa/ Ai: outer/ inner surface
Tolerances
Limit deviations for innner height h3
- upper dimension: + 0.015 * Da or 10 mm (the relevant higher value is admissible)
- under dimension: 0
| Edge forms |
|---|
| Form R (roh) |
| Form I (plan) |
| Form VA (V-seam external, 30°) |
| Form VI (V-seam internal, 30°) |
