Product Range SEUTHE

SEUTHE's core competence for many decades are customized tube welding and section lines/roll forming. Whereby no two tube welding lines are the same, as, of course, the design takes into account the different customers’ demands, for example line capacity, local conditions, operation and maintenance effort, visualization or degree of automation as well as the latest technologies and developments - with every new project to the same degree.

SEUTHE always has a keen sense of the market and the customer. New technologies and changes in market demands require a quick adjustment of the machine builder. SEUTHE designs, engineers and manufacturers standard products and customized, sophisticated precision tube welding lines according to the following requirements:

State-of-the art standard tube welding lines
SEUTHE’s high quality standards are reflected in the standardized and attractively priced basic tube welding lines which are more and more included in the portfolio due to increased demand. Also standard tube mills are always on the cutting edge of technology, as new technologies from the special purpose machinery manufacture are incorporated in their design.

Conventional forming: fast and accurate

SEUTHE manufactures classic tube welding lines with conventional forming technology to produce tubes in dimensions from 4.76 to 406.0 mm, rectangular tubes with comparable dimensions and a wall thickness of up to 16.0 mm and tube lengths between 4,000 and 18,000 mm. There are various forming processes. The conventional forming is suitable for precision or thick-wall tube welding lines.

Tube welding lines with cage forming CTA® technology

One of the patented SEUTHE technologies is the CTA (Central Tool Adjustment) cage forming method for the direct forming of round tubes already developed in 1986. This efficient and economic technology has significant influence on the quality of the tubes and the subsequent processes. SEUTHE engineers further developed this method in the last 10 years to the technically 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 thanks to CTA in about half an hour depending on the tube mill complexity.

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).

Tube welding lines with cage forming FCF® technology

Anyone who wants to economically produce shaped tubes (square/rectangular) very fast and very flexible in the dimension change will find out that SEUTHE tube welding lines with a patented forming method are technologically far ahead. Already in 1993 VAI SEUTHE has developed the cage forming FCF technology (Flexible Cold Forming), a method to directly form tubes without a previous round tube - in different dimensions, small batches and intermediate sizes. The direct forming avoids a thickening in material in the corner radii and provides an optimal utilization of the strip material. Consequently between 2 to 5 % material can be saved by using the cage forming FCF technology. As a next step of development "retrofitting", barcode readers as well as the use of state-of-the-art communication protocols are planned.

Economical production of smallest quantities

The principle of the FCF technology is simple, but convincing: The metal strip is fed from the coil in the forming section and then pulled continuously by tools. Universal, centrally adjustable roll sets for direct forming of square and rectangular sections in the range of 20x20 mm to 400x400 mm allow extremely fast dimension changes. This results in an economic production of especially very small quantities.

Benefits of cage forming FCF technology at a glance:

• Reproducible settings
• High availability
• Cost-effective production
• Minimal tooling costs
• Flexible production of all intermediate sizes
• Simple operation
• Fastest changeover times
