RESIN PIPE FOR FUEL CELL, AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a resin pipe for a fuel cell, superior in oil resistance against rancid fuel oil and in watertightness at a joint part between a pipe body and a joint, and to provide a method of manufacturing the same.SOLUTION: An inner face resin layer 3 and the joint 6 are each formed of an ethylene-tetrafluoroethylene-hexafluoropropylene copolymer which has carbonate groups and/or carboxylic acid halide groups on polymer chain terminals or side chains, or an ethylene-tetrafluoroethylene copolymer which has carboxy groups and/or carboxylic acid anhydride groups thereon so that a resin covers the whole surface which contacts flowing fluid. The inner face resin layer 3 and the joint 6 formed of the same resin are melted and adhered to each other to be integrated in a highly watertight manner at the joint part between the pipe body 2 and the joint 6 integrated with each other.
