Cold cutting machine to
revolutionise pipe replacement
THE Pipeswizard Excalibur cold
cutting and bevelling machine is set
to revolutionise the pipe bevelling
industry, according to its manufacturer,
particularly the replacement of pipeline
sections in the field.
Previous chain driven cold cutting
machines have been limited by the wall
thickness they are capable of bevelling.
This is because the designs, many of
which are 30 years old, are unable
to cope with the rigours of modern
pipelines.
PSW was given the contract to
redesign and manufacture the Mathey
CGM machine in 2007. Its own product,
the Excalibur, has been developed as
a result of listening to the people who
use the machines, and incorporating
their suggestions and requests.
The Excalibur is capable of severing
pipe with a wall thickness of up to 2";
some competing machines can only
Pipeswizard Excalibur pipe cutting and bevelling machine
cope with wall thicknesses up to ½". The Excalibur also
offers a wide variety of bevels, including J prep, U prep and
compound bevel.
Three drive options are available: hydraulic, pneumatic
and electric. The hydraulic unit is powered by either an
electric or a diesel driver power pack, also manufactured and
supplied by PSW. This delivers 72l/min at 100 bar pressure
for optimal performance. The pneumatic unit requires a
compressor capable of delivering 10 bar at 4,000l/min, while
the electric unit runs from a three-phase power supply.
The hydraulic- and pneumatic-driven Excalibur machines
are explosion proof, and can therefore be used on pipes that
have previously transported oil or gas. Due to its electrical
components, the electric-driven Excalibur machine is suitable
for use in fabrication shops/yards, but is not suitable for use
in explosive environments.
The Excalibur has a tracking accuracy of 0.3mm on a
36" pipe (reduced to 0.05mm when used with an optional
guide track), and is capable of cutting and bevelling 1" wall
thickness X70 pipe at over 30mm/min. It is also able to work
on vertical pipe.
The customer only has to order the required chain length
and cutting blades to make the machine fully functional,
straight from the box; there are no ‘hidden extras’ such as
hoses, tools or wheels.
Manufactured in the EU, and issued with full CE and
Conformity certification to 2006/42/EC, the Excalibur
conforms to all relevant EU safety regulations.
