The development, manufacture & applications of glass reinforced plastic pipes

As a result of the increasing costs of protecting conventional pipes a number of alternative pipe materials have been introduced in the last two decades with considerable emphasis on plastics. Thus a range of thermo‐plastics such as PVC or Polyethylene have been used for both pressure and non pressure applications in the smaller diameters but the most significant addition to the range of pipe materials has been that of fibre reinforced composites particularly glass fibre reinforced plastics (GRP).
