Structure CompositionOuter layer: Aluminum alloy tube, made of 6063 extruded aluminum, heat-treated and extruded into seamless aluminum tube, followed by anodizing process, with an anodized coating thickness of over 10μm. Inner layer: Food-grade PP-R tube, both layers are pre-stressed and compounded to form a double-layer composite pipe.

Performance Features

  • Pressure-resistant and aging-resistantAluminum alloy layers effectively resist UV radiation, enhance the aging resistance of pipelines, extend their service life, and the pipelines overall have good pressure resistance, making them suitable for exposed installations.
  • Excellent oxygen barrier propertiesAluminum alloy layers effectively block oxygen from seeping in, overcoming the drawback of single plastic pipes, which are prone to microbial and algae growth, ensuring clean water quality.
  • Easy installation: Only 1/6 the weight of galvanized pipes, easy to handle, features hot melt connections without threading, easy to master, quick installation, and the hot melt joints are less prone to leakage, ensuring maintenance-free pipeline systems.
  • Stable trafficInside wall smooth, non-scaling, low conveying resistance, ensures stable flow.
  • Insulation and Energy-SavingThe inner layer of polypropylene has a low thermal conductivity, offering excellent thermal insulation properties and effective energy-saving results.
  • Sanitation and SafetyThe inner layer is made of food-grade PPR material, compliant with relevant hygiene standards. The aluminum alloy layer also acts as a barrier against external contamination, preventing metal ions from seeping into the water, providing dual protection for water quality safety.

Connection MethodTypically utilizing heat-fusion connections, the pipe fittings are designed with modified polypropylene PP-R. Each curved and flexible double-fusion fitting features heat-fusion insertion positioning marks on the surface, preventing issues like incomplete fusion and leaks, thereby enhancing installation efficiency and quality.

Application ScopeSuitable for residential, hotel, hospital, and other facilities' domestic hot and cold water supply. Also applicable to the supply and return water systems of central air conditioning and potable water pipelines. In municipal construction, it can be used for urban water supply systems as well.

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