Title
(EN) REINFORCED COMPOSITE POLYETHYLENE PIPE AND A METHOD OF MANUFACTURING SAME
(FR) TUYAU DE POLYÉTHYLÈNE COMPOSITE RENFORCÉ ET PROCÉDÉ DE FABRICATION DE CELUI-CI
Abstract
(EN)
A thin walled cross-linked polyethylene (PEX) pipe having a reinforcing material disposed around an exterior wall thereof is provided. As the PEX pipe passes through an extrusion die, a thread guide applies a plurality of reinforcing threads in a particular pattern to the exterior surface thereof to allow for uniform three-dimensional (axial and radial) tensile properties so as to achieve optimum reinforcement of the pipe wall while maintaining its flexibility and without significantly increasing the thickness of the wall or the weight of the PEX pipe.
(FR)
L'invention concerne un tube de polyéthylène réticulé (PEX) à parois minces comportant un matériau de renforcement disposé de part et d'autre d'une paroi extérieure. Lorsque ce tube PEX passe au travers d'une filière pour tubes, un fil-guide applique une pluralité de fils de renforcement selon un motif particulier à la surface extérieure de celui-ci de façon à obtenir des propriétés de traction uniformes tridimensionnelles (axiales et radiales), afin de réaliser un renforcement optimal de la paroi du tube tout en préservant sa flexibilité et sans augmenter nettement l'épaisseur de la paroi ni le poids du tube PEX.
