ELECTRIC FUSION JOINT, AND SYNTHETIC RESIN PIPE JUNCTION PART

摘要

PROBLEM TO BE SOLVED: To prevent generation of peeling of fused interfaces at a junction part of a synthetic resin pipe using an electric fusion joint and pipe cracking so as to improve water leak resistance.

SOLUTION: This pipe junction part is provided with a socket 12 for a counter synthetic resin pipe 2 to be inserted. A heat wire 14 is embedded on the inner circumferential side of the socket 12, so that interfaces of an inner surface of the socket and an outer surface at an end part of the counter synthetic resin pipe are fused with each other. A bend rigidity regulating member 3 (a cylindrical or spiral body) that is longer than an inlet end e of the socket 12 is inserted into the counter synthetic resin pipe 2.
