Length
The supplied lengths are subject to the following distinctions:
a) Production lengths between 4 and 7 m are supplied - unless otherwise agreed. The lengths per order item are not permitted to vary by more than 2 m.
b) Fixed lengths with a permissible deviation from the ordered length of ± 500 mm. Up to 10 % of the delivered quantity may deviate from the fixed length, but not by more than 2 m.
c) Cut-to-length. Extremely narrow tolerances can be agreed for the ordered length.
Further details can be found in our General Product Range.
Delivery conditions
| Designation | Symbol | Description |
| Normalized | +N | After the last cold forming pass, the tubes are normalized in a controlled atmosphere. |
| Welded and size-rolled | +CR1 | Material in this delivery condition is normally not heat treated but can be subjected to final annealing. |
| Welded and size-rolled | +CR2 | After welding and size-rolling, no heat treatment is performed. |
Our Technical Sales would be happy to support you with its application expertise. You can find further details of our welded precision steel tubes in our General Product Range.
