In the Swiss city Mühlethurnen the old water line from cast iron had to be replaced by a new HDPE pipe. This pipe renewal job was done by the specialist M/s Rudolf Frutig. The first section of the old pipe had a diameter of 100 mm (4”), all other sections were 125 mm (5”). The new pipe was the HDPE pipe OD 250 mm (10”) which served as a protection for the 180 mm (7”) product pipe. The large expander cone DA 324 mm (12.75”) required a burster with high pulling forces. Mr. Rudolf Frutig decided to use his cable burster TERRA-EXTRACTOR X 400 with pulling forces of 400 kN (40 tons).
