PIPE COUPLING STRUCTURE AND MANUFACTURE THEREOF

摘要

PROBLEM TO BE SOLVED: To inexpensively provide a pipe coupling structure which remarkably improves durability for large force such as vibration and bending applied to the pipe coupling structure and torsion and instantaneous impact, enabling the adoption of various kinds of connecting means with a pipe to be connected or an equipment. SOLUTION: This structure is a pipe coupling structure 1 provided with each of a pipe to be connected P, one more pipe to be connected P or a connecting means with an equipment is provided at both end parts 5, 9 of a pipe main body 3. The pipe main body 3 is thermoplastically and integrally molded by using elastic resin for an intermediate part 13 hard thermoplastic resin for both side parts of the intermediate part 13.
