Advantages of Our Copper tube
Superior Thermal Conductivity and Energy Efficiency
Our copper tubes possess exceptionally high thermal conductivity, ranking among the best in metallic materials. This makes them the ideal choice for air conditioners, heat exchangers, and condensers, significantly enhancing heat exchange efficiency and reducing energy consumption. The high-purity material ensures uniform heat transfer, helping to optimize the performance of the entire HVAC system.
Seamless Pressure-Resistant Structure and High Installation Flexibility
Utilizing a one-piece seamless manufacturing process, our copper tubes offer excellent pressure resistance, safely handling high-pressure refrigerants like R410A. Meanwhile, the tubes feature superior ductility, making them easy to bend, flare, and weld without cracking or leakage. This not only simplifies on-site installation but also ensures structural integrity for long-term operation.
Excellent Corrosion Resistance and Hygienic Safety
Copper naturally possesses outstanding corrosion resistance and inhibits bacterial growth, making our tubes perform excellently in drinking water systems and medical gas delivery. It does not leach harmful substances over time, nor does it embrittle or release toxins at extreme temperatures. Whether buried or exposed, its long service life saves customers significant maintenance costs.

FAQs
Are your copper tubes degreased? How does this affect my AC system's compressor?
Our ACR grade copper tubes undergo strict degreasing, ensuring the inner walls are free of oil and impurities. This high cleanliness prevents residues from entering the refrigeration cycle, effectively protecting compressor valves and avoiding system blockages—a mandatory requirement for R410A or R32 high-pressure systems.
How should I choose between Type K, L, and M copper tubes? What are the differences in their pressure ratings?
The primary difference lies in wall thickness: Type K (Heavy Wall) offers the highest pressure rating for underground or heavy industrial use; Type L (Standard) is the universal choice for commercial plumbing and HVAC; Type M (Thin Wall) is typically used for low-pressure residential water lines. We recommend the most cost-effective spec based on your design pressure (PSI).
Do the copper tubes kink or crack easily during 90-degree or 180-degree bending?
Our copper tubes possess excellent ductility. Soft (O) coils are perfect for manual bending without kinking, while straight pipes (Hard or Half-hard) maintain smoothness when using bending tools. This ensures smooth fluid flow and no stress damage even in complex piping environments.
How is the brazing performance? How can I ensure no leakage during high-pressure operation?
Our seamless copper tubes feature uniform material properties, ideal for silver or copper-phosphorus brazing. By using Eddy Current Testing to eliminate minor defects and maintaining precise roundness, we ensure a perfect fit at joints, effectively preventing refrigerant micro-leaks in high-pressure, vibrating environments.
Will the copper tubes experience formicary corrosion (pitting) in coastal or humid environments?
We use high-purity Phosphorus-Deoxidized Copper (C12200), which offers better resistance to pitting than standard materials. For extreme environments, we also offer PVC Coated copper tubes or external spray protection. Copper’s natural corrosion resistance ensures an expected service life of over 50 years in water systems or chemical transport.
