Description

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 conditionsCopper Nickel Pipe CuNi 90 10 and CuNi 70 30 alloys designed for seawater piping heat exchangers and offshore oil and gas platforms
