초록

An apparatus and method for forming a fusion welded butt joint between thermoplastic pipe sections. Thermoplastic tubular insert sleeves having end flanges are inserted into the ends of the pipe sections with the flanges located in abutting relation. A coupling collar mounting a heating device is slid along one of the pipe sections into overlying relation with the butt joint formed by the engaged flanges. The heating device is energized to fusion weld the coupling sleeve to the pipe sections and to the flanges. The insert sleeves internally support the b...
