説明

PEX pipe is widely used as the material of pipes for water supply including hot water. We used sample pipes that had been used in the field for approximately 15 years to examine their deterioration conditions through mechanistic diagnosis (i.e. tensile strength test, bend test, etc.) and chemical diagnosis (i.e. heat aging test). The results suggest no evidence of deterioration of the pipes for both cold and hot water. OIT shows that the coupling of hot water feed pipes had the maximum deterioration. However, it was assumed that its remaining life should be approximate 60 years.
