Method of and apparatus for reinforcing pipe

Abstract

Reinforcing bands of high tensile strength filaments in a cured resin matrix are in the shape of a coil having a plurality of elastic convolutions for reinforcing a weakened pipe. Areas of depressions on the exterior surface of the pipe are filled with a load transfer filler material and the bands are coiled around the pipe with adhesive holding an innermost convolution of the coil to the pipe and subsequent convolutions of the coil to adjacent convolutions. A plurality of the bands are placed in abutment with one another to cover the entire weakened area of the pipe.
