Abstract
A method of lining installed pipework which includes the steps of: taking a length of liner pipe of memory retaining plastics material and of an external diameter greater than the internal diameter of the pipework to be lined, drawing the liner pipe through a swaging die, preheating the liner pipe before the swaging step to a temperature between 35]C and 90]C, the said swaging step being effected under tension using pulling means threaded through the pipework and attached to the leading end of the liner pipe to reduce the external diameter of the liner pipe, and the tension applied by the pulling means being such as partially to restrain the radial expansion of the outer surface of the liner pipe after its emergence from the die, drawing the liner pipe through the installed pipework with its outer diameter reduced to a dimension less than that of the inner diameter of the pipework, and after drawing the liner pipe through the installed pipework allowing the liner pipe to expand within the pipework by relaxation of the tension followed by memory induced expansion at ordinary atmospheric pressure and at the ambient temperature of the pipework.
