• The heads avaiable in stock are formed with flat edge (TF1), for heads with a different edge, you kindly would specify to our customer office.
• The above drawings are not to scale and should be taken purely as an example.
• The edge TF2 is shown in its standard version, but it can also be made to satisfy different exigences
D Outside diameter
Di Inside diameter
R Dish radius
r Knuckle radius
h Height of straight flange
Ht Overall external height = H+h+s
H overall internal height without straight flange
Sv Diameter of the blank
V Capacity in litres of the dished head
The tolerances applied for the pressed heads are defined according to the applicable norms (particularly the norm AFNOR NF E 81-100).
For the rolled heads are as follows:
On the external diameter:
< Ø 2000 = ± 2 ‰ • Ø
> Ø 2000 = ± 3 ‰ • Ø
(difference between the minimum diameter and the maximum diameter):
± 3 ‰ • Ø
(for heads with raw edge):
-0 + 25mm
The tolerances of dimensions and shape of the sheets to be used for reference, unless otherwise agreed, are in accordance with UNI EN 10025 and UNI EN 10051.
However, it is possible at the time of the order to require more limited tolerances for which feasibility will be studied.
