REINFORCED COMPOSITE POLYETHYLENE PIPE AND A METHOD OF MANUFACTURING SAME

摘要

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.
