Aluminum-plastic composite pipe FAQ
1. What makes Aluminum-plastic composite pipe better than traditional pipes?
Aluminum-plastic composite pipe offers several advantages including superior corrosion resistance compared to metal pipes, better thermal stability than pure plastic pipes, and excellent oxygen barrier properties. The aluminum core prevents oxygen diffusion that can corrode heating systems, while the plastic layers eliminate scaling and mineral buildup common in metal pipes.
2. How do I install Aluminum-plastic composite pipe?
Installation requires proper cutting tools to ensure clean cuts without deforming the pipe. Use compression fittings specifically designed for Aluminum-plastic composite pipe. The pipe can be bent by hand (for diameters up to 32mm) without requiring elbows, but should never be bent tighter than 5 times its diameter. Always follow the manufacturer's installation guidelines for optimal performance.
3. Can Aluminum-plastic composite pipe be used for drinking water?
Yes, high-quality Aluminum-plastic composite pipe meets all international standards for drinking water applications (EN ISO 21003, NSF/ANSI 61). The inner polyethylene layer is food-grade material that doesn't affect water taste or quality. However, always verify that the specific product has relevant certifications for potable water use in your region.
