Title
(EN) REINFORCED PIPE AND METHOD OF MAKING
(FR) TUYAU RENFORCE ET PROCEDE DE FABRICATION
Abstract
(EN)
A reinforced pipe (10) and a method for constructing same wherein the reinforced pipe is comprised of an outer pipe (14) concentrically positioned over an inner pipe (13). A honeycomb, reinforcing material (15) which is comprised of rows of cells (15C) is positioned between the pipes with the longitudinal axis of each cell (15C) being aligned with a radius of the inner pipe (13). The outer pipe (14) may be heat shrunk onto the honeycomb material (15) or it may be split and expanded before positioning over the honeycomb material (15). Both the honeycomb material (15) and the outer pipe (14) are positioned along only a portion of the length of the inner pipe so that each end of the inner pipe (13) is exposed to facilitate the joining of two adjacent lengths of reinforced pipe.
(FR)
L'invention concerne un tuyau renforcé et un procédé de fabrication dudit tuyau. Le tuyau renforcé est constitué d'un tuyau externe concentrique entourant un tuyau interne. Un matériau renforcé en nid d'abeilles, composé de rangées de cellules, est placé entre les tuyaux, chaque axe longitudinal d'une cellule étant aligné avec un rayon du tuyau interne. Le tuyau externe peut être thermorétracté sur le matériau en nid d'abeilles, ou fendu et expansé avant d'être placé sur le matériau en nid d'abeilles. Le matériau en nid d'abeilles et le tuyau externe sont disposés uniquement le long d'une partie de la longueur du tuyau interne, si bien que chaque extrémité du tuyau interne est exposée pour faciliter le jointage de deux longueurs adjacentes du tuyau renforcé.
