What are the typical material grades used for Copper Coiled Tubes?
- C12200 TP2 (Oxygen-Free Copper) – Soft-annealed and 99.9% pure, offering high ductility and thermal conductivity. Ideal for HVAC, refrigeration, and plumbing applications where coiling and bending are required.
- C10200 (ETP Copper) – Electrolytic tough pitch copper, widely used for industrial and HVAC piping. Balances strength, flexibility, and corrosion resistance, making it suitable for standard piping systems.
- Cu-DHP (Deoxidized High-Phosphorus Copper) – Common in EN 12735 tubes, it provides enhanced corrosion resistance and maintains good mechanical strength for district heating and industrial applications.
How do soft-annealed copper coiled tubes differ from hard-drawn copper tubes?
- Soft-Annealed Tubes:
- Can be bent and coiled without cracking.
- Ideal for tight-radius HVAC, refrigeration, and plumbing applications.
- Lower tensile strength but higher ductility (elongation ≥ 35%).
- Hard-Drawn Tubes:
- Stronger and more rigid, but limited flexibility.
- Often used where structural support or pressure resistance is more critical than bending.
How do copper coiled tubes compare with copper-nickel alloys like 90/10 or 70/30?
- Copper Coiled Tubes (ASTM B280 / EN 12735):
- Made of high-purity copper, soft-annealed, mainly for HVAC, refrigeration, and plumbing.
- Excellent thermal conductivity and ductility.
- Copper-Nickel Alloys (90/10, 70/30):
- Added nickel for higher corrosion resistance in seawater or chemical environments.
- Lower thermal conductivity but higher strength in aggressive environments.
- Conclusion: Pure copper is ideal for general HVAC/plumbing; Cu-Ni alloys are preferred for marine or chemical applications.
