**Basic Characteristics of PPR Lined Aluminum Alloy:** 1. The outer pipe of the aluminum alloy lined plastic composite pipe is made of aluminum alloy, while the inner layer is made of thermoplastic, which ensures cleaner water quality. Water does not come into contact with the aluminum alloy, making it hygienic and extending the service life of the pipe to up to 50 years. In contrast, metal pipes are usually made of galvanized steel, copper, cast iron, stainless steel, aluminum alloy, nickel-plated steel, coated steel, etc., which are prone to rusting on the outer pipe and can accumulate dirt on the inner pipe, leading to a shorter lifespan. 2. The aluminum sheet in the PPR lined aluminum alloy completely isolates oxygen, eliminating the possibility of oxidation, corrosion, and permeation. 3. The polyethylene in the PPR lined aluminum alloy does not accumulate scale, allowing for a greater flow rate compared to metal pipes. 4. The polyethylene in the PPR lined aluminum alloy is resistant to corrosion and has antistatic properties, making it suitable for engineering applications involving the transportation of chemicals and fuels; metal pipes do not possess corrosion resistance. 5. Metal pipes cannot be bent, while aluminum alloy lined plastic composite pipes can be flexibly curved without rebounding, which helps reduce the number of joints to avoid flow obstruction and leakage. 6. In terms of weight, copper pipes are 3-4 times heavier, and galvanized iron pipes are 15-17 times heavier than PPR lined aluminum alloy pipes. The aluminum alloy lined plastic composite pipe is lightweight, making it easier to handle and reducing the load on buildings. 7. The installation of PPR lined aluminum alloy is simple and quick, requiring only basic joints for installation. It can be easily cut with pipe cutters and installed around beams and in partitions. As with any composite pipe, the bonding strength between different materials in PPR lined aluminum alloy is crucial for preventing leakage; metal pipes have a high density and poor impermeability.
