• Quick and accurate alignment of pipe during welding operations
  • Field proven in thousand of miles of pipeline construction under the most extreme field conditions.
  • Front and rear heads operate independently to lock the clamps into position.
  • Specially designed shoes on each head exert pressure uniformly around the inside circumference of the pipe to maintain necessary alignment .
  • Each Clamps is quickly and easily adjusted for different pipe wall thickness.
  • Clamps 16” (406.4 mm) or larger are self-propelled with powerful air motors that drive the clamps forward through the pipe to the next joint .
