TPT July 2011

T HE J ULY I SSUE Welcome to the latest issue of Tube & Pipe Technology magazine, which includes features on Cutting, Sawing & Saw Blades; Coating, Pickling & Galvanising as well as show information on Tube Southeast ASIA and EMO. As you can see it has been a busy couple of months in the tube industry and it is only set to get busier. Just the way we all like it. The TPT team was recently at Tube Russia and had a great trip to (sunny) Moscow by all accounts, meeting many old friends and plenty of new contacts and enjoying some great Russian hospitality. The magazine will of course be represented at all the major tube shows coming up including the China (Guangzhou) Tube & Pipe Industry Exhibition and we are already making our preparations for our annual trip to Fabtech. And don’t forget that the biggest of them all is Tube Düsseldorf, which, believe it or not, is now just under a year away. Time to start planning. Next issue we have features on the latest developments in welding as well as a bumper show feature on Fabtech and Tubotech Brazil is also coming up in October. Rory McBride – Editor

The roots of EFD Induction go back to the launch in 1950 of a universal induction hardening machine by the German company Induktionserwärmung Fritz Düsseldorf GmbH (FDF). While FDF was expanding in the 1970s, an induction revolution was taking place in Norway, where engineers had figured out how to transistorise frequency converters for induction heating. In 1981 three of those engineers founded ELVA Induksjon. In 1983 they unveiled the Minac range of mobile converters. Workpieces no longer had to be brought at great cost to a stationary induction heater – the heater could now go to the piece. In 1991 the managing directors of FDF and ELVA met by chance. They talked… and speculated. FDF was strong in stationary induction hardening machines. ELVA was the agile innovator with a track record in finding new applications for induction heating. What if the two companies got together? In January 1996 FDF and ELVA merged to create EFD Induction. And the rest is, as they say, history. Today, EFD Induction is Europe’s largest supplier of induction solutions for industry (number two worldwide, but they aim to change that!). If you’d like to know more about them, their products, and how they can help boost your productivity, just get in touch.
