Corrosion-free welded connection for reinforced thermoplastic pipes (RTP)

A connection system, comprising:

• a first pipe having a first end;
• a reinforced thermoset resin (RTR) coupler positioned adjacent the first end of the first pipe,
• the RTR coupler, comprising:
• an annular body having a first socket extension extending into the first end of the first pipe, wherein the annular body comprises an RTR material,
• wherein the annular body of the RTR coupler comprises a radial extension extending in a direction perpendicular from the first socket extension,
• wherein a first flange is connected to the radial extension of the RTR coupler via at least one connector extending through the radial extension;
• 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 positioned circumferentially around an outer surface of the first end of the first pipe;
• and
• the first flange fitted around the first set of wedges, wherein the first set of wedges is wedged between the first end and the first flange.
