Abstract: A visual inspection apparatus (18) is disclosed for viewing welds between pipe sections (26, 28). The apparatus (18) can be part of a combination plug clamp and inspection apparatus (12) or used independently of the plug clamp (12). The TV camera (20) is aimed along the center line axis (52) of the apparatus and pipeline and a mirror (76) reflects the image of a portion of the weld into the lens of the camera. The mirror can be rotated to allow the entire circumference of the weld to be inspected. A weighted ring (102) provides a reference relative to the vertical independent of the orientation of the apparatus within the pipeline.

Abstract: A line-up clamp (10) is disclosed for clamping small diameter pipe sections together for welding. The line-up clamp includes back-up shoe assemblies (106) which are pivoted into engagement with the interior surfaces of the pipe sections adjacent the weld as the clamp clamps the pipe sections. As the hydraulic cylinder (14) compresses the resilient disks, expanding the disks into clamping contact with the pipe sections, actuator bodies (58, 88) are urged together, with tapered surfaces on facing back-up shoe assemblies moving into contact and driving the back-up shoe assemblies into contact with the interior surfaces of the pipe sections at the point of welding.
