Structure CompositionOuter layer: Aluminum alloy tube, made of 6063 aluminum by heat-extruded forming into seamless aluminum tube, followed by anodizing treatment, with an anodic 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 also offer good overall pressure resistance, making them suitable for exposed installation.
- Excellent oxygen barrier propertiesAluminum alloy layers effectively block oxygen from渗透，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, uses hot melt connections without threading, is easy to master, installs quickly, and the hot melt joints are less prone to leakage, achieving maintenance-free pipeline systems.
- Stable trafficInner wall smooth, non-scaling, low conveying resistance, ensuring stable flow.
- Insulation and Energy ConservationThe inner layer of polypropylene has low thermal conductivity, offering excellent insulation properties and effective energy-saving results.
- Sanitation and SafetyThe inner layer is made of food-grade PPR material, compliant with relevant hygiene standards, and the aluminum alloy layer isolates external contamination, preventing metal ions from渗入水体, offering dual protection for water quality safety.
Connection MethodTypically utilizing hot melt connections, the pipe fittings are designed with modified polypropylene PP-R. Each elbow and double-fusion fitting features a thermal melt insertion positioning mark on the surface, preventing issues like incomplete or leaking melts, thereby enhancing installation efficiency and quality.
Application ScopeSuitable for domestic, hotel, hospital, and other facilities' hot and cold water supply; also applicable to the supply and return water systems of central air conditioning and drinking water pipelines. In municipal construction, it can also be used in urban water supply systems.
Standard of ImplementationThe execution standard is CJ/T 321-2010, which specifies specific requirements for pipe dimensions and performance.
