Orbital cutting of tubes
TUBE cutting is a necessary machining operation for the
prefabrication, construction, maintenance, repair or removal
of damaged parts caused by corrosion, for example. Tubular
components are affected by channelled substances that
affect the original condition of the tube. Oil, gas or water at
high pressures are abrasive and can alter the corrosion of
the tube chemically and/or mechanically.
When the replacement of the tube is absolutely necessary,
the cut is made in upstream and downstream sections of the
damaged tube. This maintenance operation can be done on-
site and requires the best equipment for a perfect surface
quality before performing welding operations. Protem tube
cutting and bevelling machines are portable. They are
lightweight, reliable, easy to use and they ensure a perfect
weld preparation with no heat affected zones on all types
of materials, such as steel or inox tubes.
The Protem product range includes several types of
cutting and bevelling machines: TT-NG orbital cutting
machines cut and bevel tubes with large wall thicknesses;
the TT-LW series machines, with a simpler design, cut and
bevel tubes up to 25.4mm (1"); The TTS-NG machines
allow accurate cutting and/or bevelling of tubes and pipes,
of all schedules, from 10.3mm (0.406") up to 273mm
(10.7") OD in one simultaneous operation; and the TTS-
RD machines have been specially developed to cut thin-
walled tubes from steel and titanium in restrictive space
conditions.
They are composed of two rings: one fixed and one
rotating. The tool holders are mounted onto these rings. They
can be opened into two “half-shells”, which allows them to
be mounted on any type of pipe at the required place for
machining. They perform simultaneous welding preparation
operations in order to get a regular land, an appropriate
counterboring if necessary, and a bevel as desired.
The CTA – high-speed cutting and bevelling – machines
tubes and pipes with OD diameters ranging from 60.3mm
(2") to 914.4mm (36"). Tubes are cut and bevelled within just
a few seconds.
The TNO are high-speed cutting and bevelling machines
that are designed to fit piping or tubing prefab applications,
on-site or in workshops.
