The September Issue
Welcome to the latest Tube & Pipe
Technology magazine. This issue we
have a feature on bending, end forming
and swaging and a technical article
written by the legendary Willy Goellner
from Advanced Machine & Engineering/
AMSAW on resonance – the destructive
force behind carbide saw breakdowns.
This month we also take a look at FABTECH 2016
and Tube India 2016, both shows that this issue will
be distributed at along with EuroBLECH in Germany. I
am returning to Tube India again in October after last
visiting in 2012. It will be interesting to see how the tube
machinery industry has developed over the past four
years as the country has been on the cusp of becoming
one of the world’s strongest economies for a while now.
More than 400 exhibitors from around 25 countries
are expected to attend the event so it is very much an
international occasion.
Next up we have the November issue, which will have
features on cutting, sawing and profiling technology;
tube extrusion, drawing and end forming; and drilling,
piercing and punching technology. The advertising
deadline for next issue is 12 September. You can contact
me at: if you would like to submit
editorial or if you would like any information about
submitting technical articles.
I hope you enjoy the magazine.
