Description

Cylindrical turned parts manufactured from Mannesmann precision steel tubes are characterized by their cost-effectiveness, low eccentricity, and tight tolerances on both external and internal dimensions. Mannesmann can also calculate the corresponding machining allowances (e.g., oversize allowances).

Your benefits

  • Lower material consumption
  • Fewer processing steps
  • Shorter cycle times
  • Improved machine utilization

Lengths

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.

Standards & materials

We produce our steel tubes in accordance with internationally recognized standards and use different, carefully selected materials depending on the application. You will find various standards and the materials specified therein under the following link. Further standards can be agreed on request. Additionally, properties and materials outside the usual standards can be specified and agreed. Our Technical Customer Support will support you in all matters relating to material selection and technology.

Tests

We conduct tests in accordance with the requirements of the relevant standard.

Additional tests can be agreed upon.

Tube processing

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.

Engineering

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.
