The supplied lengths are subject to the following distinctions:
a) Production lengths between 4 and 7 m are supplied, failing agreement to the contrary. 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.
|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.|
