Deformation of small tubes
IRON’S Technology was founded in
2011 by Rudi Bragagni, Marco Senni
and Andrea Ancarani, who started
to study plastic deformation of small
diameter tubes for heat exchange
application.
At present there is no technology able
to realise any given shape – it is only
possible to create small deformations by
rolling. Studies and simulations demon-
strate that increasing exchange surface
and creating turbulence inside the tube
improve heat exchange with a high
energy saving. This necessity has given
rise to the idea of creating a machine
able to work off line tubes after produc-
tion and realising the optimal desired
shape. After four years of studies, Iron’s
Technology’s engineers created a pro-
totype machine and developed the soft-
ware, and the complete new technology
has been patented. The technology was
then improved in order to obtain further
and more distorted shapes.
The MAS1 machine is now able to
perform cold and hot plastic deformation
on tubes with diameters ranging between
10-12 and 500mm, and thickness ranging
from 2 to 8-10mm.
The machine’s working principle
is inspired by the lathe, but works by
deformation rather than cutting. Two
tools work in opposition on a carriage
that has a translation movement
along the axle of the tube itself. The
combination of pipe rotation and tools
translation allows deformations able
to realise a virtually infinite number of
shapes. The technology of the MAS1
makes it possible to use tools of
different kinds and materials together
with several combinations of pitch, tilt
angle and depth.
Iron’s Technology provides three size
of MAS1, depending on the size of the
tube and deformation requested: S, EL
and HT series.

End-prep
A NEW electric OD clamping end-
prep tool for use on both thin-wall and
heavy-wall tubes with a high percentage
of chrome, especially in high purity
applications, is being introduced by
Mactech Europe.
The tool has a large clamp that
grips tubing from the outside, evenly
distributing the holding power, to ensure
a chatter-free precision end-prep on both
thin-wall and heavy-wall tubes. Featuring
a 950W electric motor and requiring no
cutting oils, the end-prep tool is suitable
for use on high-purity piping systems
requiring 37½° bevels, flat-facing,
J-preps or orbital welding.
