At Tube India International 2012 (October 30-November 01, 2012, Bombay Convention & Exhibition Centre, Goregaon (E), Mumbai), Schwarze-Robitec GmbH will present the new tube cold-bending machine CNC 100 DB on stand 1G26 in hall 1. The innovation was developed specifically for bending boiler tubes and tube coils in demanding materials. Having been founded in 1903, Schwarze-Robitec is among the international leading experts in the area of tube bending machines.

"Ultimately, efficiency inside the combustion chamber is dependent on the tubes used providing the greatest possible area for heat transfer with the tightest possible bending radii. This is not new. However, the bending challenge behind it is much greater due to the high-strength materials," explains Schwarze-Robitec Managing Director Bert Zorn. With the CNC 100 DB tube cold-bending machine, the specialists have constructed the required plant innovation and further developed their special booster bending machine process without mandrel. The primary consideration here was the regulation of the plant. On the one hand, greater bending forces are needed in order to cold shape the harder tubes. On the other hand, the material reacts more sensitively. The process of the CNC 100 DB has consequently been optimised in order to reliably achieve results a 1D bending radius even with high-strength materials. "As such, with our booster bending solution, we ensure that a minimal reduction in wall thickness occurs in tube bending process. Particularly in the use of high-strength materials, this offers a noticeable cost advantage," adds Managing Director Hartmut St?hr.

Overall, the CNC 100 DB is a development of the range of systems from Schwarze-Robitec for tube processing in power plant construction. For over 45 years, the specialists have constructed the required bending technology for the production of tube and membrane walls, burner port tubes and supply lines. "With the CNC 100 DB, we are making the vital step to supporting innovations in power plant construction with a perfectly fitted solution," Bert Zorn expounds on the range for power plant construction.
