A PLASTIC PIPE FOR COUPLING FUSION TYPE OF GLOBE AND RING

摘要

A plastic pipe for coupling is provided to prevent water leakage by fusion-coupling an outer coupling portion of a coupling ring to a ring groove of a coupling member and fusion-coupling an inner coupling portion of the coupling ring to the plastic pipe. A coupling ring includes a cushion member(23), an outer coupling portion(21), and an inner coupling portion(24). The cushion member is positioned in ring grooves(12) formed at both sides of a main body(11) of a coupling member. The outer coupling portion is integrally coupled to an outer surface of the cushion member, and has an inside with a heating cable(22). The inner coupling portion is integrally coupled to an inner surface of the cushion member, and has an inside with a heating cable(27). The ring grooves and the plastic pipe are integrally fusion-coupled to each other by a lead wire(28) connected to the heating cables.
