PROCEDURE

Pipe sting pull in

After the pre reams procedures, the Pulling Head and connecting product pipe are attached to the reamer using a Swivel, a device that isolates the pipe string from the rotation of the HDD drill pipe “Rod”.

The product pipe is then pulled behind the final reamer back through the horizontal directional drill path to the exit pit on the rig side.
