METHOD FOR ATTACHING METALLIC FLANGES TO THERMAL PLASTIC DUCTS

摘要

A method is provided for connecting a fitting to a reinforced thermoplastic duct including inserting a first end of the fitting having a plurality of barbs into an end of the duct. A clamp is installed around the duct. The duct is heated to a temperature greater than a glass transition temperature of a thermal plastic material used to form the duct. The duct is restructured to include a plurality of protrusions positioned between the plurality of barbs of the fitting.
