Out of the curve with no loss of cross-section

The outlets are precisely positioned, and can be installed directly in the boiler. After bending, the pipe coil is moved into a fully automated processing system that cuts the pipe ends without burrs, and axially forms a cone. A frontal sealing surface for flat- sealing elements is also attached as a conical thread cut. This combination makes it possible for the customer for this special transfluid system to seal both frontally and on the threads. Another advantage of the process is that the processing of extremely thin-walled pipe is supported, and all processes are completed without burrs. This ensures clean fabrication and efficiency in the production process. transfluid Maschinenbau GmbH – Germany Fax: +49 2972 971511 drive and a set of cleaning brushes of the customer’s choice. The flexibility and robust nature of the Rotaflex makes regular duct cleaning an easy activity to include in maintenance schedules. Boiler tube cleaning can reduce fuel consumption and increase boiler efficiency. The variety of accessories available for the Rotaflex mean that boiler tube cleaning can be carried out quickly and effectively. “The Rotaflex has been used to unblock heat exchanger tubes at a chocolate factory, clean condenser tubes at a power station in Turkey and as part of a regular duct cleaning routine for an international fast food chain,” said Mr Wright.

GmbH has put its right-hand/left-hand bending machines to use in a specially developed system. The coiled material is first placed into a measuring device by a robot. Here, the exact diameter and length of the pipe coil is entered to define the orientation and position of the outlets. The machine then positions

WHEREVER boilers let warm water flow or heat exchangers do their energy- efficient work, pipe coils are needed as system components. Before the coiled pipes are ready to use, the outlets have to be machined, precisely and with no loss of cross-sectional area. For this challenge, transfluid Maschinenbau

attachments available, is able to clean various tube sizes on equipment within many different industrial sectors,” said Chris Wright, sales administrator for the Rotaflex. Rotaflex is easy for one person to operate, making it suitable for companies with limited maintenance budgets. The system features a new electronic controller that provides the required 3-phase, variable-speed power supply, and makes the Rotaflex easier to handle and move around. The flexible driveshaft has also been improved, with the addition of a blue, food-grade covering. The flexi-drive is claimed to be so robust that a truck can drive over it. For longer tubes or pipes there is also a heavy-duty, chassis-based version of Rotaflex that can power a 20m flexi- drive. New Rotaflex machines are usually ordered with an 8m or 12m flexi-

INITIALLY designed for the cleaning of mill spouts within the flour milling sector, the Rotaflex™ cleaning system has proved effective in the cleaning of pipe work, heat exchanger tubes and boiler tubes. “The Rotaflex is a sturdy, portable cleaning system that, due to the various
