Development Prospects of Aluminum Alloy Lined Plastic Pipes
With the technological development of modern industry, the aluminum alloy lined plastic composite pipe independently developed by Runshuo Pipe Industry is a new type of practical pipeline developed based on traditional plastic pipes. It combines the physicochemical advantages of both metal and plastic materials. In addition to ensuring superior sanitary and pressure-resistant performance, it also has significant features such as frost resistance, thermal insulation, noise reduction, corrosion resistance, shock resistance(impact resistance), light weight and rigidity, and a maintenance-free system for fifty years, which aligns with modern environmental protection advocacy. Ordinary plastic pipes, when exposed to heat(water/gas), will deform, making it impossible to achieve a level and straight shape, and unable to block ultraviolet radiation and oxygen that could corrode pipelines and associated metal components, leading to a significantly shortened lifespan. Therefore, they cannot meet the requirement of being used for fifty years under specified pressure and temperature ranges.
The aluminum alloy lined plastic composite pipe is not only durable but also environmentally friendly, meeting the rational needs of people. The aluminum alloy lined plastic composite pipe, led by Runshuo Pipe Industry, is gradually replacing traditional plastic pipes in many fields.
Characteristics:
1. Healthy and environmentally friendly, non-toxic and antibacterial. Made from food safety-grade water contact materials, resistant to chemical pollution, and reduces noise during transportation; thermal insulation, with heat loss along the line only 1/200 compared to metal pipes, smooth transportation, not easy to scale, with a friction resistance coefficient of only 0.007.
2. Sturdy structure. Lightweight rigid pipe, level and straight, not easy to break, with a full-length heat fusion socket connection that eliminates leakage risks. The unique design of the fittings prevents spillage; resistant to low temperatures, corrosion, oxygen, and no electrochemical corrosion, and the system can operate maintenance-free for over 50 years, withstanding nominal pressures up to PN2.5Mpa.
3. Powerful functionality, widely applicable. Cold and hot water supply systems for buildings; heating and central air conditioning systems for buildings; various food sanitation, drinking water, and pharmaceutical preparation pipeline systems; various chemical agent and hospital medication delivery pipeline systems.
Luxurious Appearance — The aluminum alloy lined plastic composite pipe has an aesthetically pleasing appearance with a metallic luster. It overcomes the shortcomings of plastic pipes that deform and bend when heated. The quality of aluminum alloy lined plastic composite pipes is only about one-fifth of that of other metal pipes, effectively reducing the load on buildings, making it suitable for main water supply and heating pipes in buildings such as residential and commercial buildings, hotels, and living communities, thereby enhancing the overall quality and grade of the buildings.
Higher Heat Resistance — Due to the protection of the external metal layer(aluminum layer), the internal lining is prevented from experiencing elastic creep under heat and pressure, and plastic creep will not occur. Therefore, aluminum alloy lined plastic pipes can withstand higher temperatures than pure plastic pipes, and their service life is also longer.
50 Years Maintenance-Free — The inner and outer layer materials used in aluminum alloy lined plastic composite pipes are all domestic raw materials. Under normal usage conditions, the pipeline system will maintain its aesthetic and sturdy characteristics for a long time without incurring additional costs for rust and corrosion prevention. The unique inner lining of aluminum alloy lined plastic composite pipes forms a unit with the outer aluminum pipe after heat fusion connection, and the good processing technology at the joint position avoids the risk of bursting pipes and installation pollution, overcoming the phenomenon of pipeline damage caused by rust in ordinary metal pipes.
Green and Environmentally Friendly — The inner lining of the aluminum alloy lined plastic composite pipe is made of PP-R/PE-RT/PB/PE materials, which do not chemically react with ions in water or any chemicals that may come into contact; for instance, the molecules of PP-R raw materials only contain carbon and hydrogen elements, without any harmful elements, being sanitary and non-toxic, corrosion-resistant and non-scaling, making it a green and environmentally friendly product suitable for pure drinking water systems, liquid beverage delivery systems, and liquid medication delivery systems. The production, construction, and use of aluminum alloy lined plastic composite pipes do not cause any pollution to the environment.
The definition of aluminum alloy lined plastic composite pipes is according to the standard CJ/T321-2010, which defines the aluminum alloy lined plastic composite pipe as: a double-layer composite pipe with an outer layer of aluminum alloy and an inner layer of thermoplastic pipe, formed by prestressed composite; the outer aluminum pipe is a seamless aluminum pipe made from 6063 deformed aluminum, shaped by heating and extrusion, and then treated with anodizing process (the anodized coating thickness of the aluminum pipe surface is ≥10μ).
Aluminum alloy lined plastic composite pipes are widely used, and based on different inner lining materials, their application fields also include: sand and gravel transportation systems in mines and islands; water, gas, and oil transportation systems in oil fields; natural gas transportation systems in residential areas, etc.
