Enhanced production of ‘spiral wound’ corrugated pipe

Magnetic welding angles INDUSTRIAL Magnetics, Inc (IMI) provides permanent magnet devices for use in material handling, work holding and automated or robotic applications. The company’s two new switchable, rare earth magnetic welding angles allow welders to set up, weld, and quickly move on to their next job with fast, easy on/off magnet control. A simple turn of a knob activates and deactivates its holding power, which allows precise placement and control and a non-marring release. The adjustable welding angle works on flat or pipe surfaces and easily allows debris to fall away. The on/off, 90° magnetic welding angle is suitable for 90° heavy weld jobs and allows precise placement and strong holding power. Its versatile design includes pre-drilled holes that allow for the addition of magnetic bases for extreme holding power. Industrial Magnetics, Inc – USA

THERMATOOL has announced the successful commissioning of another CFC 150kW solid-state HF contact welder, which has recently been installed on a line producing high frequency welded ‘spiral wound’ corrugated pipe. Spiral wound corrugated pipe is particularly suited for use in water drainage applications, where the corrugation serves to increase the radial strength of the pipe, making it suitable for storm drains installed under roads, car parks and areas where water run-off is an environmental concern. The installation produces water culvert and drainage pipe from both aluminised and galvanisedsteelmaterial,withouter diameters over the range 12" to 12ft (305 to 3,658mm) and wall thickness of between 0.035" and 0.165" (0.9 to 4.2mm), at production speeds up to 100ft/min (30m/min). Thermatool CFC series HF welders provide an alternative to the traditional lock seam method of producing this type of product. Thermatool’s solid-state HF

welding solution also delivers a high quality, water-tight forge weld and eliminates the waste of 6" (152mm) of material that would otherwise be consumed on the previous lock seam. Additional claimed benefits are greater product strength, higher production speeds and improved electrical efficiency. Thermatool Corp – USA
