Multi-rifled tubes

The supplied lengths are subject to the following distinctions:

a) Production lengths between 4 and 7 m (13.123 - 22.966 ft) are supplied - unless otherwise agreed. The lengths per order item are not permitted to vary by more than 2 m (6.561 ft).

b) Fixed lengths with a permissible deviation from the ordered length of ± 500 mm (1.64 ft). Up to 10 % of the delivered quantity may deviate from the fixed length, but not by more than 2 m (6.561 ft).

c) Cut-to-length. Extremely narrow tolerances can be agreed for the ordered length.

We have acquired our expertise over many years and offer a wide range of possible further processing steps for steel tubes. We actively support you with your plans - from sawing and machining of the tube blank to complex bending and upsetting operations.

We can also reduce eccentricity and improve concentricity by turning and grinding, create complex geometries with processes such as rotary swaging and axial forming, and modify properties with the aid of partial heat treatment.

Do you have any questions regarding the further processing of tubes to tubular components for engineering purposes? Our experts will be happy to support you. If required, we accompany the entire process - from the idea to the development and production of pre-series parts and prototypes to the product ready for series production.

Depending on the intended application, we advise you on the selection of the right tube production route, suitable heat treatment, and the necessary processing steps - which includes useful surface protection strategies. For this purpose, we have a wide range of options for computation and simulation as well as testing and measuring processes available.
