Characteristics of Aluminum Alloy Lined Plastic Round Pipes
Aluminum alloy pipes are a new type of practical pipeline developed based on traditional plastic pipes, combining the physical and chemical advantages of both metal and plastic materials. They are lightweight, oxygen-resistant, UV-resistant, clean and hygienic, easy to install, have strong sealing properties, and require no maintenance in water supply applications.
In indoor exposed installations, they solve the defects of plastic pipes such as bending due to thermal expansion and contraction, vulnerability to impacts, and aging.
Connection Method
Heat fusion socket connection, saving time and effort.
Applicable Scope
Mainly suitable for cold and hot water supply in buildings, including industrial, civil cold and hot water, and heating systems.
Product Advantages
1. Unique Mechanical Properties: Aluminum alloy lined plastic composite pipes are lightweight rigid pipes that will not suffer loss or damage due to accidental impacts, strikes, or compression during installation and use.
2. Thermal Performance: The thermal conductivity of the inner polypropylene layer of aluminum alloy lined plastic composite pipes is 0.24 W/mK, and it remains constant between 20℃ and 60℃. Pipes produced using this material have excellent thermal insulation properties.
3. Economic Efficiency: The melt flow rate variation of the inner polypropylene layer of aluminum alloy lined plastic composite pipes is minimal, with the melt index variation rate generally being <6% for the same product model. Even after multiple thermal plasticizations, it can still maintain its original excellent performance, greatly improving the recyclability of raw materials and reducing production costs.
4. Long-term Static Pressure Resistance: The resistance to long-term static pressure directly affects the service life of water supply pipelines. Aluminum alloy lined plastic composite pipes have better hydraulic resistance than similar pipes after hydraulic testing, with polypropylene pipes and fittings providing good long-term static pressure resistance and an extremely long service life.
5. Good Weldability: The heat fusion joints of the pipes will not crack or develop shrink holes due to poor heat fusion, preventing leaks and achieving maintenance-free pipeline systems, which is a typical characteristic of polypropylene pipes.
