What is the difference between PPR pipe and aluminium plastic pipe?
PPR is plastic. It must be provided with special heating tools when it is built. Without tools, you can't get the route yourself, and you can only walk at right anglesThe plastic pipe is different with a wrench themselves will be able to route construction also you can bend.However, in advance to draw a good road map, budget, or have to run to replace pipe fittings, very tired
From the aging resistance performance, aluminum pipe stable molecular structure inner layer outer layer PE apart, allowed to join the enough anti light, anti oxygen stabilizer and does not affect the inner health water contact; PE molecular structure is stable, but the single structure is not conducive to the addition of stabilizer is easy to cause two pollution in water pipeline; pipe containing PP-R a large number of tertiary carbon atom is unstable, vulnerable to light, oxygen and impurities and aging
From the high temperature performance, long-term use temperature of aluminum pipe GB is 95 DEG C, maximum temperature is 110 DEG C, can fully meet the need of household water; PE pipe as the temperature increases the performance decreased rapidly, only cold water transport; long-term use of GB PP-R temperature is 70 DEG C, the highest temperature is 95 C, there are some limitations in the use of hot water tube.
From the long-term health performance, the aluminum pipe in the middle layer of oxygen isolation, not easy to cause microbial and algal plants, and the outer PE allowed antioxidants, will not cause water pollution inside the inner layer. PE pipe and PP-R pipe can not obstruct oxygen, can easily lead to microbial and algal blooms, the health effects of drinking water; and contain large amounts of antioxidants, caused by water pollution.
From the connection way, aluminum plastic pipe is a physical connection, simple and convenient, unless the operation is improper, its safety and reliability is very high. PE and PP-R using hot-melt or fused connection, complex process, easy to produce stacking defects, lead to stress concentration, influencing the long-term performance of pipeline; in addition, the local high temperature fuse facilitates pipeline material degradation, accelerated aging pipeline.
