Abstract (en)
[origin: WO9003260A1] A liner (10) for a pipe (14) includes an imperforate inner tube (12), a first fiber matrix (16) surrounding the tube, a layer of resin impregnated open cell foam (18) surrounding the first fiber matrix (16), and a second fiber matrix (20) surrounding the layer of open cell foam (18). The foam (18) is radially compressed by a pig (30) causing the resin to flow through the first and second fiber matrices (16 and 20) into bonding contact with the tube (12) and pipe (14), respectively.
