TT Technologies pipe bursting system

The Grundoburst static pipe bursting system from TT Technologies can pull in a variety of replacement pipe including PVC, DIP, ABS, cast iron, fusion-welded HDPE and VCP jacking pipe. It uses a bladed cutter head to burst ductile iron and steel pipe, pulled by a hydraulic bursting unit, while the cutter head’s cutting wheels split the host pipe. An attached expander spreads and displaces the split pipe into the surrounding soil while simultaneously pulling in the new pipe. Bursting rods are linked together, not threaded, to prevent twisting. Six models are available for bursting 2- through 54-inch pipes and larger. 800/533-2078;
