Structure CompositionOuter layer: Seamless aluminum tube made of 6063 aluminum alloy, extruded and formed by heating. Anodized coating with thickness exceeding 10μm. Inner layer: Food-grade PP-R tube. Both layers are pre-stressed and compounded to form a double-layer composite tube structure.

Performance Features

  • Pressure-resistant and aging-resistantAluminum alloy layers effectively resist UV radiation, enhance the pipeline's anti-aging properties, extend its service life, and the pipeline maintains good pressure resistance, making it suitable for exposed installation.
  • Excellent oxygen impermeability propertiesAluminum alloy layers effectively block oxygen from seeping in, overcoming the drawback of single plastic pipes that easily lead to the proliferation of microorganisms and algae, ensuring clean water quality.
  • Easy installationThe weight is only 1/6 of galvanized pipes, easy to handle, and requires no threading for hot melt connections. The operation is easy to master, installation is quick, and the hot melt joints are less prone to leakage, achieving maintenance-free pipeline systems.
  • Stable trafficInternal wall smooth, non-scaling, with low conveying resistance, ensuring stable flow.
  • Insulation and Energy-SavingThe inner layer of polypropylene has low thermal conductivity, offering excellent insulation properties and effective energy-saving results.
  • Sanitary SafetyThe inner layer is made of food-grade PPR material, complying with relevant hygiene standards. The aluminum alloy layer acts as a barrier against external contamination, preventing metal ions from seeping into the water, offering dual protection for water quality safety.

Connection methodTypically, heat fusion connections are used, with pipe fittings designed in modified polypropylene PP-R. Each curved and elastic double-fusion pipe fitting features thermal fusion insertion positioning indicators on its surface, preventing issues such as incomplete fusion and leakage, thereby enhancing installation efficiency and quality.

Application ScopeSuitable for domestic, hotel, hospital, and other locations, providing cold and hot water supply. Also applicable to the supply and return water systems of central air conditioning and potable water pipelines. In municipal construction, it can also be used in urban water supply systems.

Implementation StandardsThe execution standard is CJ/T 321-2010, which specifies specific requirements for pipeline dimensions and performance.
