FOAMED POLYOLEFIN RESIN COATED COMPOUND PIPING AND PRODUCTION PROCESS THEREOF

摘要

PROBLEM TO BE SOLVED: To provide foamed polyolefin resin coated compound piping capable of preventing the mutual separation of the piping during handling and separating without breaking its skin sheet even if branched by peeling a joint in an application.

SOLUTION: A peeling load of the joint is set to 43 N or larger in the foamed polyolefin resin coated compound piping which is obtained by mutually cementing the skin sheets in each of plurality of foamed polyolefin resin coated pipes in the longitudinal direction with an adhesive where the foamed polyolefin resin coated pipe is formed by coating the pipe with a foaming heat insulating material and coating the foaming heat insulating material with the skin sheet.
