Detailed Product Description

we are highly appraised by the wide clients,the products have been widely used in projects of water supply,fuel gas supply,solar energy ,heating and related household decoration projects.the products sell well in large cities all over chian and win unanimous praise from nationwide clients.and obtained good social and economic beneift.the products have been acknowledged by  experts of relevant state departments as a new breakthrough in pipeline engineering,and ensured integration of pipes and fittings without worry about seepage and leakage at the pipe joints.

1,Survey of the products: compound pipe, the pipe is multiple layers formed with two or more than two-layer heat moldable plastic and one-layer embedded metal layer. PP-R plastic aluminium Stationary Pipe is integrated organically of PP-R plastic and metal, and also has flexibility of plastic pipe and rigidity of metal pipe. It reaches steady mechanical character by integrative aluminium layer, and also has the higher intensity and better anti-temperature character. On the base of PP-R pipe, we adopt heat melding adhering technique to agglutinate organically between PP-R and alloy aluminium under high temperature, outside covered with PP-R(PE) protective layer and then produce the PP-R plastic aluminium stationary pipe. PP-R plastic aluminium stationary pipe has polypropylene-glue-aluminium-glue-polypropylene five-layer structure. The middle aluminium layer has fortified effect. The European countries, used in water supply, heating, central air conditioning etc, especially Germany does better in this field.    

  2The character of technical performance: PP-R plastic aluminium stationary pipe is integrated with the advantages of PP-R pipe and metal pipe and it is also clean, sealed, and rigidity of metal pipe. It forms the special character that is better than other plastic pipe. It also has the physical character of small linear expansion coefficient, no penetrating oxygen, anti-ultraviolet radiation, high intensity, high anti-temperature etc.
      2.1 the small linear expansion coefficient: The linear expansion coefficient of PP-R aluminium plastic stationary pipe is the one in five of common PP-R pipe. (Common PP-R pipe is 0.15 mm/m K), and it is near the metal pipe. The pipe doesnt have the property of expanding with heat and contracting with cold. In the project fixing, we dont need to consider about the distortion problem, when we are fixing the pipe which is less than 40 meters. But we should consider about prevention pipe, when the length of horizontal fixing is more than 40 meters.
     2.2 No penetrating oxygen, cleanness.
     2.3? Anti-ultraviolet radiation
     2.4 Compressive strength and good anti-temperature
     2.5 Heat fusion connection and no penetrating 

3 The comparison of PP-R plastic aluminium stationary pipe and the PP-R aluminium plastic pipe.
       3.1 The structure of PP-R plastic aluminium stationary pipe is reasonable, the stability is high: PP-R plastic aluminium stationary pipe technique character and project application.
       3.2 Connect reliably and high security
       3.3 Good performance of anti-ultraviolet radiation
       3.4 Environment protection

4 The preponderant application field of PP-R plastic aluminium
      4.1 Hot water, central air conditioning, warming by radiator
      4.2 Outside pipe in and out the room
      4.3 The pipe system outside, like solar energy pipe system.
