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.
