1. Product Description
Copper-nickel pipes are seamless or welded tubular products made from copper-nickel alloys (typically CuNi 90/10 or CuNi 70/30), known for their excellent corrosion resistance and thermal conductivity.
2. Key Parameters
Common Alloys: CuNi 90/10 (UNS C70600) and CuNi 70/30 (UNS C71500)
Size Range: Outer diameter 6–610 mm; wall thickness 0.5–20 mm
Operating Temperature: –200°C to +350°C
Density: ~8.9 g/cm³
Thermal Conductivity: ~29–45 W/(m·K)
3. Applications
Marine engineering (seawater piping, heat exchangers, condensers)
Offshore oil & gas platforms
Shipbuilding (cooling and fire-fighting systems)
Desalination plants and power generation stations
4. Advantages
Exceptional resistance to seawater and biofouling
High resistance to stress corrosion cracking and erosion
Good fabricability (bending, welding, and forming)
Long service life with low maintenance requirements
5. Functions
Efficient heat transfer in condensers and coolers
Reliable transport of seawater, freshwater, and aggressive fluids
Anti-microbial surface performance in certain hygiene-sensitive applications
6. Precautions
Avoid contact with ammonia, mercury, or sulfides to prevent corrosion
Use proper welding procedures (TIG or MIG) with matching filler metals
Ensure adequate flow velocity to avoid pitting or sediment accumulation
Regular inspection recommended in high-temperature or turbulent service conditions
