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; applying a continuous strip around 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 spiral sleeve spaced from the pipe surface to provide an annular chamber between the pipe surface and the spiral sleeve.
