Pipe and Vessel Fabrication

Location : Dubai, UAE

Application : Pipe Spooling

Project : 4"-30" process pipe requires cost effective weld positioning, rotation, and welding with ultimate end use in an LNG terminal.

The LJ Welding Solution : LJ supplied a combination of a pipe turning positioner, also known as a 'spinner' for economical and high torque rotation of process piping. The LJ pipe turner series have the key features of being the most economical weld positioners on the market, with very high torque output and large speed range for efficient weld positioning of any size pipe.

The Result : the customer purchased an LJ pipe turning positioner for approximately one-third the price of a conventional welding positioner, with superior output specifications. The customer was able to significantly increase their pipe welding throughput, with plans to add additional LJ pipe turning positioners in the future.

Location : Cairo, Egypt

Application : Vessel Fabrication

Project : a major refinery in Egypt required specialized high capacity turning rolls

The LJ Welding Solution : LJ supplied a fully customized, state of the art 200 metric ton turning roll set, complete with high precision digital speed output, driveshaft free dual drive, powered lead screw wheel spacing, and hydraulic height adjustability under full load: a truly state of the art welding rotator.

The Result : enormous time savings and safety improvements, allowing the customer to level, align, and lift massive pressure vessels under full load and rotate during welding process.

Location : Alberta, Canada

Application : Multi-purpose welding

Project : customer required an all-purpose machine for welding of pipe, small vessels, and flanges for various oilfield applications

The LJ Welding Solution : customized tilt/turn welding positioner with extra height range to accommodate large swing diameters, customized input power, and extra speed range.

The Result : the customer was able to use the tilt/turn positioner for pipe welding functions and traditional tilt/turn weld positioning functions, eliminating the need to purchase more expensive dedicated welding positioners.
