A system and method of repairing a pipe including securing a reinforcing material, such as a dry fiber structure (12) (e.g., a carbon fibers) to the surface of the pipe (14). A polymeric material (41) is placed on top of the reinforcing material, self-penetrating the dry fiber structure. The polymeric material substantially saturates the reinforcing material and cures to form a reinforced polymeric composite which may increase or restore the pressure rating or operating pressure capacity of the pipe. Optionally, an outer containment component (36), such as a sleeve, shell, box, wall, outer pipe, and so on, may be installed around the reinforcing material prior to introduction of the polymeric material. In this case, the polymeric material may be placed (i.e., poured) into the interior of the containment component on top of the reinforcing material.
Système et méthode de réparation de tuyaux consistant à fixer un matériau de renfort tel qu'une structure en fibre sèche (12) (en fibre de carbone, par exemple) sur la surface du tuyau (14). Sur le matériau de renfort vient se placer un matériau polymère (41) qui pénètre de lui-même dans la structure en fibre sèche. Ce matériau polymère sature sensiblement le matériau de renfort et, une fois durci, forme un composite polymère renforcé qui peut accroître ou rétablir la pression nominale ou la capacité de pression de travail du tuyau. En variante, on peut monter une pièce de confinement (36) - manchon, coquille, boîtier, cloison, tuyau extérieur, etc. autour du matériau de renfort avant mise en place du matériau polymère, auquel cas ledit matériau polymère peut être coulé à l'intérieur de la pièce de confinement et sur le matériau de renfort.
