to the core of
your welding
process?
CAVILUX® Welding monitoring solutions enable
you to see the welding process as cold.
You can monitor as well as adjust your
process right away once a defect has been
detected.
Get never-before-seen visual information
on such things as seam position, melt pool
behaviour and drop forming of filler material.

Orbital tube and
pipe cutting
and bevelling
machines
PROTEM tube cutting and bevelling machines are portable
machines that are light, reliable, easy to use and they allow
the user to get a perfect preparation with no thermally affected
zones. They are composed of two rings: one fixed and one
rotating.
The tube cutting machines of the TT-NGseries are accurate
in cutting and/or bevelling tubes and pipes of all schedules
individually or in one simultaneous operation. These
machines are especially designed to machine heavy wall
tubes and pipes. They can have a pneumatic or hydraulic
motorisation,with electrical drives on request.
The machines are very robust and can be installed in
various positions. Their split frame configuration allows their
opening in two half-shells. For the manual clamping four
independent adjustable jaws are used. The machines have a
rear centring feature and completely enclosed drive gears for
the operators’ safety.
The TT-NG can be equipped with ovality copying slides
enabling to correct the defects of ovality of tubes and pipes.
They can also be remotely controlled for operations in areas
under ionizing radiations.
The machines of the Protem TT-NG series can machine
pipes with diameters ranging from 60.3mm (2") up to
2,082.8mm (82") OD and over on request. Several
configurations of tool holders are available including wheel
holders enabling for example for the replacement of steam
generators to cut on a 90mm wall thickness with severing
tools and to cut the remaining 10mm with wheels in order to
reduce the production of chips and thus contamination.

Fast cutting
SAWING bar or tube is a machining process that all too often
leaves the operator to decide the speed of the blade and the
downfeed rate, which means it is the operator who dictates
the cutting efficiency and, therefore, the actual cost. However
it is possible to take the guesswork out of the process and
to achieve significantly improved production rates as well as
longer blade life.
Danobat’s range of heavy-duty automatic horizontal
bandsaws offers a maximum round cutting capacity of 420mm
for the smallest model up to 1,100mm for the largest model.
