Abstract
A connection system for reinforced thermoplastic polymer (RTP) pipe includes a first pipe with a first end and a reinforced thermoset resin (RTR) coupler positioned adjacent to the first end of the first pipe. The RTR coupler has an annular body with a first socket extension extending into the first end of the first pipe and a first thermoplastic tie layer provided between the first socket extension and the first end of the first pipe. A first set of wedges is positioned around an outer surface of the first end of the first pipe, and a first flange is fitted around the first set of wedges, wherein the first set of wedges is wedged between the first end and the first flange.
