Aluminum and plastic PP-R pipe
PPR-AL-PPR
Jiuhao aluminum and plastic PP-R pipes are comprised by five layers, interlayer is thin-walled aluminum, outer layer is PP-R, inner layer is PE or PP-R, with imported glue between layer and layer, combine them together through high temperature.
Features:
Combines advantages of plastic and metal pipes: anti-Corrosion, light weight, high mechanical strength, good heat resistance, no rust, long service life.
Application: can be applied in heating, solar energy, papermaking, chemical, textile, pharmaceutical, environmental protection, industrial and civil engineering
