HOT WATER PIPE USED FOR HOT WATER MAT FOR HOT WATER TYPE FLOOR HEATING

摘要

PROBLEM TO BE SOLVED: To prevent corrosion and degradation of efficiency caused by oxidation generated by oxygen mixed into hot water in a hot water pipe of a hot water mat, resulting in requiring air bleeding and the like.;SOLUTION: The hot water pipe 4 is formed in four-sort four-layer structure by forming a crosslinked polyethylene layer as a first layer 6, an admer layer as a second layer 7 serving as an adhesive, an EVOH layer as a third layer 8 serving as an oxygen barrier layer using the adhesive, and a crosslinked polyethylene layer compounding admer as a fourth layer 9 outside the EVOH layer.;COPYRIGHT: (C)2010,JPO&INPIT
