General

The SPM EQUIPMENT’S Internal Pneumatic Clamp With Copper Back Up Shoe assures a rapid, accurate alignment of two joints of pipe during the welding operation. Front and rear heads operate independently to lock the clamp into position.

Specially designed shoes on each head exert pressure uniformly around the inside circumference of the pipe to maintain necessary alignment. Each Internal Line Up Pneumatic Clamp is easily and quickly adjusted for different pipe wall thickness.
