<p>Aluminum pipe, pe pipe, pp-r pipe and other properties of several water pipe difference The current home improvement market commonly used aluminum-plastic pipe, PE pipe, PP-R pipe due to the different materials and technology, there are also large differences in performance. From the connection point of view, aluminum pipe is a physical connection, simple, convenient, unless improper operation, its safety and reliability is very high. PE and PP-R are hot melt or fused connection, the process is complex, easy to produce stacking defect area, resulting in stress concentration, affecting the long-term performance of the pipeline; In addition, the local high temperature fuse easy to promote pipeline material degradation.</p><p> The From the long-term health performance, aluminum aluminum tube in the middle of the aluminum layer of oxygen, not easy to lead to microbial and algae breeding, the general outer PE to allow antioxidants, will not cause the inner water pollution, PE pipe and PP-R pipe can not be blocked Oxygen, easily lead to microbial and algae reproduction, affecting the health of drinking water; and contains a large number of antioxidants, easily lead to water pollution. From the high temperature performance, aluminum-plastic pipe GB standard long-term use of the temperature of 95 ℃, the maximum temperature of 110 ℃</p><p>fully meet the needs of domestic water; PE pipe with the temperature rise of its performance decreased rapidly, limited to cold water PP-R GB standard long-term use of the temperature of 70 ℃, the maximum temperature of 95 ℃, the use of hot water pipe has some limitations. From the anti-aging properties, aluminum-plastic pipe molecular structure is stable, the inner and outer PE separated, the outer layer to allow enough anti-light, antioxidant without affecting the inner water exposure; PE pipe molecular structure is stable, but single Layer structure is not conducive to adding stabilizers, easy to lead to secondary pollution in the pipeline water; PP-R tube contains a large number of unstable tertiary carbon atoms, susceptible to light, oxygen, impurities and aging.</p>
