BASED on the experience of metal tape
forming and welding technology for the
international wire and cable industry,
Rosendahl has extended its product
portfolio for the production of metal
tubes. For continuous tube welding
lines, Rosendahl offers turnkey solutions
including tape forming, tube welding, tube
sizing and corrugation technology.
For the production of longitudinally
welded tubes, an exact preparation and
guiding of the tape edges is required.
Rosendahl secures this preciseness by
considering material properties, the design
of the forming stations and forming tools.
Different materials and applications
require different welding technologies. With
regard to economic efficiency Rosendahl
provides solutions with TIG, plasma and
laser welding technologies.
To reach the dimensional accuracy
and the product properties in special
applications, Rosendahl offers static and
dynamic tube calibration.
Corrugated tubes combine mechanic
stability and bending flexibility. The
corrugation profile significantly influences
the product characteristics. Depending
on the task, Rosendahl offers efficient
solutions for the tube production.
The product range is supplemented
through adequate auxiliary down stream
equipment, including solutions for metal
tape handling and preparation and tube
coiling, in order to support customised
solutions.
The product portfolio covers production
lines for solar, automotive, medical and
industrial tube applications. Rosendahl
provides solutions for copper, aluminium
and stainless steel for smooth and
corrugated products.
