Aluminum-plastic composite pipe is the earliest water supply pipe to replace cast iron pipe. It is basically composed of five layers, from the inside to the outside, they are plastic, hot melt adhesive, aluminum alloy, hot melt adhesive, and plastic. So what are the advantages of aluminum-plastic composite pipes?

1. Excellent hygienic performance: The inner and outer layers of the aluminum-plastic composite pipe are made of special polyethylene materials, which are clean and non-toxic. The most important thing is that the middle layer of the aluminum-plastic pipe is aluminum, which not only blocks light but also blocks oxygen. As we all know, the environment for microorganisms must have light and oxygen. The middle aluminum layer of the aluminum-plastic composite pipe prevents the growth of microorganisms and algae, which is something that all-plastic pipes cannot achieve. This also provides users with good life safety protection.

2. Excellent high and low temperature resistance: tested at a long-term use temperature of 95 degrees, and the highest temperature ever tested was 135 degrees. Moreover, the thermal expansion coefficient of aluminum products is very small, so the expansion of aluminum-plastic composite pipes is also very small, and only full-plastic pipes one-sixth. When subjected to temperature changes, the amount of deformation is small, and the aluminum-plastic composite pipe is a flexible coil. The pipe itself can absorb a certain amount of deformation without causing thermal expansion and deformation of the piping system. The high and low temperature resistance of all-plastic pipes is relatively poor.

3. Long service life: This is a commitment to consumers and a confidence in aluminum-plastic composite pipes. The PE plastic used in aluminum-plastic composite pipes has a molecular chain structure (-CH2-CH2-) that is relatively stable among plastics. Stable, and because the aluminum layer in the middle of the aluminum-plastic pipe isolates the inner and outer layers, the outer plastic allows the addition of stabilizers that are sufficient to resist light and oxygen aging without affecting the hygiene of the inner layer in contact with water, thereby enhancing its anti-aging performance.
