TPT May 2012

T HE M AY I SSUE Welcome to the latest Tube & Pipe Technology magazine. This issue we have features on the important areas of cutting, sawing and profiling technology as well as inspection, testing and quality control and a look at the forthcoming Tube Russia 2012 in Moscow. We also have an in-depth technical article from one of the leading tube technology companies in China – FD Machinery – written by chief engineer Guowu Goa about recent developments in the use of AUTO-DNSA mills and ERW tube mills. Our entire team have just returned from an extremely busy and successful Tube Düsseldorf show and by all accounts it was the most enjoyable that many of us have been to for some time. There was an extremely positive atmosphere at the event, which I imagine was helped by the unusually hot weather this year, but I hope the sense of optimism goes a little deeper too in terms of an improving world economy. I spoke to leading companies from countries around the globe and the vast majority reported a very healthy increase in serious enquiries when compared to the same time two years ago when there was a lot more caution in the air. Next issue we have articles on the Tube China 2012 show, tube scarfing systems and tools and the latest developments in tube welding technology, so please feel free to submit any relevant

F RONT C OVER S TORY 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.
