CONNECTION METHOD AND STRUCTURE OF RESIN HOSE AND RESIN PIPE, AND RESIN HOSE

摘要

PROBLEM TO BE SOLVED: To improve reliability and durability in connection by exposing an inner peripheral surface of a resin hose by grinding a resin to be used as a joint surface, and then joining a joint part of a hard resin pipe having an outer diameter approximately same as that of the joint surface and the exposed hard resin. SOLUTION: An inner peripheral surface Ha of a resin hose H is ground until a hard resin 1 is exposed to a joint surface Hb, to expose the hard resin 1. The exposed hard resin 1a and a joint part 3 of a resin pipe P having an outer diameter approximately same as the joint surface Hb are joined. That is, a boundary of the inner peripheral surface Ha of the resin hose H and an inner peripheral surface 3a of the joint part 3 of the resin pipe P butted to the resin hose H is formed without difference in level, in a state of the resin pipe P fitted with the resin hose H.
