Ppr-al-ppr Stable Pipe

We are instrumental in providing to our valuable customers excellent quality PPR-AL-PPR Stable Pipe which is available with following Features:-
1. Small linear expandability coefficient, only 1/5 of the pure plastic pipe, almost equal to that of metal pipe, non-deformable with open-air installation;
2. Non-oxygen permeation and anticorrosive in operation under high temperature. The aluminum effectively isolates from air outside, prevent the oxygen permeation and metal parts from oxidation or corrosion;
3. Ultraviolet radiation resistance, aluminum layer effectively isolates from ultraviolet radiation;
4. Heat preservation, energy efficient and economical; (Heat transfer coefficient: 0.23-0.24 W/M.K, Steel: 43-52W/M.K, Copper: 383W/M.K )
5. Tight connection, easy installation. The exterior layer is convenient execute melting insertion connection with traditional PPR pipe.
