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.
I hope you enjoy the magazine.

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
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.
