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.
