Orbital welding system for heavy wall pipes

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.

High speed saw cuts 11,000 tubes per hour

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.
