  • Outline:
    DUNHUA PEX-AL-PEX pipe is a fivelayer composite pipe that combines the advantages of a metal and plastic pipe and eliminates the disadvantages of both materials at the same time. The aluminum core is absolutely diffusion tight; it reliably prevents oxygen/gases from permeating into pipe. It compensates and reduces snap-back forces and heat expansion with changes of temperature.
      DUNHUA PEX multi-layer composite pipe consists of an overlapped or butt welded aluminum core with an inner and outer layer or high temperature-resistant polyethylene. All layers are permanently bonded together by intermediate adhesive layers. The aluminum thickness for DUNHUA
    PEX pipe has been selected to meet compressive and flexural strength requirements.
      Overlapped welded PEX pipe is coextruded with one step with perfect adhesive between inner layer and aluminum, high and stable pressure resistance, of which welding style is ultrasonic.
      Butt welded PEX pipe is moulded with several steps that is argon-arc welding style.
