THE Gullco Pipe Kat® is a practical
alternative to the manual welding of heavy
wall pipes of 254mm (10") and greater. The
system produces X-ray quality welds with
robotic consistency and precision, making it
suitable for pipeline on-site work.
The Pipe Kat’s versatility allows it to
work with various power sources, keeping
overall costs low while still providing welds
that meet code requirements. Total carriage
weight less wire spool is 19kg (42lb).
The unit is mounted on the pipe by means
of a quick mount pipe band, which is available
for all standard and custom pipe diameters.
The welding torch is mounted on one side,
providing full open access to the weld joint
area. The Pipe Kat can be easily converted
for straight line welding for applications such
as tanks and shipbuilding.
Pipe Kat’s design allows it to weld pipes
as small as 254mm (10"), including flat,
horizontal or vertical welding. With an
integrated wire feeder unit the carriage
incorporates 5.6-1,016mm/min (2.2–40
IPM) welding carriage design with quick
action mounting for ease of installation.
The carriage is equipped with a high speed
return feature for fast repositioning of
the carriage. The system also features
a linear oscillator with adjustable weave
width and weld joint centreline adjustment,
and motorised vertical slide. All motorised
functions incorporate jog settings.
Wire feed spool capacity is 4.5kg (10lb),
with a maximum wire speed of 88-1,608mm/
min (36-633 IPM). Wire sizes range from
0.8mm to 2mm, and the welding torch uses
standard consumables.

KENT Corporation’s new Bewo SCF-90
high speed cold saw cuts one to six tubes
simultaneously, giving high cut rates of
up to 11,000 per hour. The saw head cuts
upward, which leaves most chips below and
requires less cutting force.
The fully hydraulic helical saw head is
robust, with minimal backlash. The saw
blades are both variable and the saw head is
proportional feed through the tube, to optimise
cut quality, blade life and production rates.
The tubes are fed via servo feed that
ensures accuracy and enables up to ten
different lengths to be cut from a single
stock length of tube. The main control
panel automatically selects the most
efficient settings based on the job typed
in. All settings are quick and automatically
controlled at the panel.
The Bewo Quatro can be expanded
with 100 per cent compatible machines
and systems for de-burring, measuring,
washing and stacking. The high speed saw
is capable of processing tubes from 8 to
90mm outside diameter (0.315" to 3.5").
Kent offers full sales, service and parts
back-up for new and used Bewo machines
in North America.
