RESIN PIPE FOR HEAT SYSTEM AND MANUFACTURING METHOD FOR RESIN PIPE

摘要

PROBLEM TO BE SOLVED: To provide a resin pipe for heat system excellent in the strength, dimensional stability and heat resistance and provide a method of manufacturing such resin pipes. SOLUTION: The fiber-reinforced resin pipe consisting of a composition containing fiber-form fillers and polyamide resin is applied to a heat system and has such a structure that the fiber-form fillers are plane oriented along a plane parallel with the surface. The manufacturing method consists of an extrusion molding process to be conducted in the condition that the surface of the molding is solidified.
