Features:

1) Structure and crafts: PAP pipe is composite pipe of five layers, inside and 

    outside layers of which are made of hight-dendity polyethylene (HDPE) 

    cross-linked (PEX) or polyethylene raised temperature (PE-RT), tightly 

    boned woth mlt adhensive to the mid-layer of aluminum core which is

    longitudinally welded in an overlapping way. All layers are extruded by one

    step

2) Facilities: Most advanced machines of the world formed the production line

3) Production criterion: national standard, GB/T18997.1-2003

4) Compared with the metal pipe, PAP pipe has the same strength, easy to 

    bend, reluctant to retain former shape

6) Super properties of high temperature, high pressure and corrosion

    resistance

7) Smooth inner surface of the pipe reduces resistance to the fluids. The

    ability to conduct water is 30% more efficient

8) Fire resistant property

9) Good property of heat preservation, heat conduction coefficient is 

    0.45W/m.k which is much less than metal pipes and it can save insulation

    materials outside the pipe

10) Ease to cut and install. It can be connected with special fittings instead 

      of screw fittings. Small diameter pipes can be rolled and packaged. Once 

      received the pipes (bent radius above 5D) can be cut to desired length 

      and simply bent in order that many directional parts such as elbows or 

      angles are no longer necessary. Very convenient to install, much time and 

      labor cost can be saved

11) Lifespan of the pipe is more than 50 years

12) Light weight, the weight is 1/10 of galvanized pipes and lower 

      transportation fees and lower cost are reduced

13) It can be served as a cable cover electric wires

14) The pipe can be used as underground piping and can be easily located 

      with a metal detector

15) The core aluminum pipe can prevent oxygen seepage to avoid the bacteria

16) Application: 

      a) Heat and cold pipes for production and life

      b) Pipeline of coal gas and natural gas

      c) Conduct of electric wire and cable

      d) Conveying potable liquids in beverage factory

      e) Heating system of caliduct, under floor and wall, the equipment for 

          snow melting in northern China

      f) Oxygen pipeline in hospital

      g) Industrial pipelines of oil and cooling liquid

      h) Piping of solar energy water heater

      i) Pipes for vacuum absorption

      j) Piping of central air-conditioning and blower

      k) Pipes for irrigation engineer in agriculture and garden

      l) Pipes for water engineer in residential area
