Tube welding lines with cage forming CTA® technology

One of the core competencies of SEUTHE which was patented in the 1990s is the CTA® (Central Tool Adjustment) cage forming technology for direct forming of round tubes. Technical know-how and expertise remain with SEUTHE as successor company of VAI SEUTHE GmbH – also available are all drawings of all lines that were ever built and delivered worldwide. This efficient and economic technology has significant influence on the quality of the tubes and the subsequent processes. SEUTHE engineers have further developed this technology in the last ten years to the technically most feasible.

Small batch sizes

In the retrofittable cage forming CTA production system the universal forming rolls are located in a roller cage which can be adjusted centrally, automatically and infinitely for the production of large size ranges. And most importantly, a dimension change which takes hours with conventional tube mills can be carried out in about half an hour depending on the tube mill complexity thanks to CTA.



Benefits of cage forming CTA technology at a glance:

  • Quick changeover times
  • Small batch sizes
  • Low tooling and storage costs
  • Production of intermediate sizes
  • Economic and efficient production
  • High tube mill availability
  • Reproducible settings
  • Minimization of stocks (capital commitment)
