The Advantage of Aluminum Plastic Tube, and The Differences Among Aluminum Plastic, PE and PP Tube

• From the point of view of connection, the aluminum plastic tube is physically connected, simple and convenient, unless improper operation, its safety and reliability is very high; PE tube and PP-R tube are connected by hot melt or electric melt, the process is complex, easy to produce tube defect area, resulting in stress concentration, affect the long-term performance of the tube; In addition, the local high temperature of the electric fuse is easy to promote the degradation of the tube material and accelerate the aging of the tube.

                                                                                                                    

• From aging resistance, the aluminum plastic tube has a stable molecular structure, both inside and outside layer are parted by PE, outer allow enough light resistance, resistance to oxygen stabilizer and not affect the inner health sexual contact with water, and because aluminous model canal middle aluminum layer inside and outside of the isolation layer, the outer plastic allowed to join enough light, oxygen aging of stabilizer and not affect the inner health sexual contact with water, So as to strengthen its anti-aging performance;
   
  PE tube’s molecular structure is stable, but the monolayer structure is not conducive to the addition of stabilizer, easy to lead to secondary pollution of water in the pipeline;
   
  PP-R pipe contains the largest and most unstable tertiary carbon atoms, vulnerable to light, oxygen, impurities and aging.

                                                                                                         

• In terms of long-term hygiene performance, the outer layer of aluminum plastic tube is made of special polyethylene material, which is clean and non-toxic. Starvation among the heaviest if aluminium tube aluminum layer, not easy to cause dead creatures and algae breeding, general outer PE allows adding antioxidants, won't cause the inner water pollution; PE tube and PP-R tube can't cut off oxygen, easily lead to bacteria and algae breeding, affect water hygiene, and contains a lot of antioxidant, easy to cause water pollution.
   

                                                                                                         

• From the view of high temperature resistance, the long-term use temperature of the national standard of aluminum tube is 95℃, the highest use temperature is 1100℃, which can fully meet the needs of household water, and the thermal expansion coefficient of aluminum tube is small, when the temperature changes, the deformation is small;
