Method for repairing and/or strengthening of pipes

摘要

A method for affecting a repair and/or strengthening of a pipe is disclosed. The method comprises cleaning an effected area of a surface of the pipe to provide a cleaned surface of the pipe surface for an area requiring repair and applying a continuous strip around 5 the pipe from a portion prior to the effected area and allowing the continuous strip to extend to a portion after the effected area. The continuous strip forms a mechanically sealed spiral sleeve spaced from the pipe surface to provide an annular chamber between the pipe surface and the mechanically sealed spiral sleeve. The method further comprises providing a plurality of spacers for spacing the spiral sleeve away from the 10 surface of the pipe and subsequently filling the annular chamber with a filling material for providing a bond between the pipe and the sleeve. 4180081_1 (GHMatters) P85837.AU.1
