WHAT IS THE KOBUS PIPE PULLER?
Simply, pipe pulling for service pipe replacement is an innovative trenchless technology. The technique removes old water or gas service pipe from the ground by pulling it with a hydraulic winch and a special steel pulling cable. At the same time, a new PE pipe is towed into place along the same bore path created by the extracted old pipe. Up to 20-25m can be extracted in a single pull. So, typical lengths of lead, copper, galvanised steel, and PE pipe found on site can all be replaced up to diameters of 1-1/4″ (OD 36mm). As a result, the process is ideal for road crossings, replacements under expensive driveways/pathways, or where other utilities may prevent other techniques being used.
