ABSTRACT:
The present disclosure sets forths a pipeline insertion mechanism. It cooperates with the pipeline having a tee, blocking valve and stuffing box. An elongate insertion rod is extended from the exterior through the stuffing box, blocking valve and tee so that a measuring instrument is positioned at a centerline location in the pipeline. This rod connects to a transverse yoke having two ends which connects at the remote ends to piston rods. Two piston rods cooperative with two hydraulically cylinders are positioned adjacent to the blocking valve and stuffing block to reduce height of the equipment. The insertion rod is moved axially to insert or retract the measuring instrument.
