  • Chapter 16 - Pipe Brusting

    Pipe bursting was first developed in the UK in the late 1970s by D. J. Ryan & Sons in conjunction with British Gas, for the replacement of small-diameter, 3- and 4-inch cast iron gas mains (Howell 1995). The process involved a pneumatically driven, cone-shaped bursting head operated by a reciprocating impact process. This method was
