The bursting starts once (1) the head is attached to the new pipe, (2) the winchcable is inserted through the old pipe and attached to the head, (3) the air compressorand the winch are set at a constant pressure and tension values. The processcontinues with little operator intervention until the head reaches the pulling shaft atwhich point it is separated from the PE Pipe.Figure 2 The Bursting Head of the Pneumatic SystemStatic Bursting SystemsThe second common method of pipe bursting is the static pull system. In the staticpull system, a larger tensile force is applied to the cone-shaped expansion head
