METHOD FOR CONNECTING RESIN PIPE

摘要

PROBLEM TO BE SOLVED: To provide a method for connecting a resin pipe capable of preventing easy breakage at a root between the resin pipe and a pipe joint side connection port heat-fused to each other. SOLUTION: The connection structure joining the connection port 4 of a resin pipe joint to the pipe end of the resin pipe fitted into the connection port by heat fusion eliminates the breakage of the resin pipe at the root to the connection port of the resin pipe joint. A ring collar 3 is thereby insert-fitted to the pipe end side of the resin pipe, and the resin pipe is heat-fused to the connection port of the resin pipe joint together with the ring collar.
