For replacement of old pipes 5'' – 20'' (Ø 125 - 500 mm) from cast iron, steel, clay ware or PE/PVC.
New HDPE pipes Ø 125 – 500 mm (5'' – 20'') are pulled in.
Lengths up to 120 m (400 ft). Maximum pulling force: 1000 kN (100 tons / 220'000 lbs / 110 US tons).
The pulling cable is slid into the old pipe. Then the cutting tool and the expander cone are assembled and are pulled in with the new HDPE pipe. At the same time the old pipe is cut in the ground.
Special cables Ø 48 mm (1.9'') are used with safety factor S=2.
Heavy mechanical cable drum recommended.
