Abstract
A clamping module for a pipe line-up system uses bell crank linkages to transmit pipe alignment and clamping forces between radially moving clamping feet and a central axially moving driving head. The clamping feet are arranged in axially spaced sets to internally engage two pipe sections to be welded independently on either side of a weld zone between the pipe sections, with welding shoes in between the clamping feet and spanning the weld zone. The bell crank linkages provide a force multiplier between the driving heads and the clamping feet.
