PROLINE Pneumatic Internal Line Up Clamps assure a rapid, accurate alignment of two joints of pipe during the welding operation. Front and rear expander sections operate independently to lock the clamp into position. Specially designed shoes on each expander section exert pressure uniformly around the inside circumference of the pipe to maintain necessary alignment. Each Lineup Clamp is quickly and easily adjusted for different pipe wall thickness. PROLINE clamps have been proven in thousands of miles of pipeline construction, under the most extreme field conditions.
The PROLINE non-powered Internal Pneumatic Line Up Clamp is a pull type suitable for use in welding small diameter steel pipe from 8″ – 18″ (203.2 mm – 457 mm). Features: Air reservoir tank.
