      They are composed of an inner and outer layer of PE-RT, which are bonded by special glue to the intermediate layer of aluminum. ASTMF1335-1998 standard called them" metal pipes with plastic protective layer".

      Advantages:

      1.Heat resistant: The highest work temperature is 95°C, working pressure is 1.25MPa.

      2.Longevity: more than 50 years under normal condition

      3.Antiknock: burst pressure can reach 6.0Mpa with safer system

      4.Better Resistance performance of oxygen

      5.Lower coefficient of heat conductivity: the lowest is 0.45W/m.k

      6.Easy to install, no connectors

      Application:

      1. Cold or hot water supply

      2. Heating system including flooring heating and radiating system

      3. Central air conditioning system

      4. Industrial liquids transportation, etc
