TPT March 2015

March/April 2015 Vol 28 No 2

The March Issue Welcome to the latest issue of Tube & Pipe Technology magazine. This month we have a feature on inspection, testing and quality control (page 86). We also take a look at Tube Russia, which takes place in Moscow in June, and Made in Steel, which will be in Milan, in May. Several members of the magazine team will be at both shows so please do come and say hello. Elsewhere in the issue there is an interesting technical article on online diameter control during hose and tube extrusion written by Harry Prunk and Katja Giersch of Sikora AG in Germany. It has been interesting to read about a number of major orders for tube machinery this issue from, for example, Schuler AG on page 6 and Olimpia 80 Srl of Italy on page 12 as well as a big acquisition for EFD induction (page 18). In May we have features on handling, bundling, packaging and logistics, tube scarfing systems and tools, plastic and composite tube production, and environmentally friendly tube technology. The editorial deadline date for our May issue of TPT is 9 March with an advertising deadline of 20 March. The magazine will be distributed at the Guangzhou trade show in China. Rory McBride – Editor

101 ARTICLE: ONLINE DIAMETER CONTROL DURING HOSE AND TUBE EXTRUSION By Harry Prunk (CEO, Sikora AG) and Ms Katja Giersch, Sikora AG, Germany

On the cover . . . The roots of EFD Induction go back to the launch in 1950 of a universal induc- tion hardening machine by the German company Induktionserwärmung Fritz Düsseldorf GmbH (FDF). While FDF was expanding in the

Putting the smarterheat to smarteruse

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 AS. 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.
