THERMOPLASTIC COMPOSITE PIPE WITH LONGITUDINAL REINFORCEMENT

摘要

A reinforced pipe includes a pipe liner, longitudinal reinforcement, and a helically wound radial reinforcement layer. The longitudinal reinforcement includes a unidirectional material generally parallel to the axis of the pipe liner. The longitudinal reinforcement prevents the pipe from expanding lengthwise, and the radial reinforcement layer prevents the pipe from expanding radially.
