CuNi 70/30 Copper Nickel Alloy Seamless Pipe, ASTM B466, for Heat Exchanger & Shipbuilding
1.Product Description
Copper nickel pipe is a copper-based alloy tube containing nickel with small additions of iron and manganese. Common grades are 90/10 CuNi (UNS C70600) and 70/30 CuNi (UNS C71500). Manufactured per ASTM B466/ASME SB466 (seamless) and ASTM B467/ASME SB467 (welded). Produced via extrusion/piercing, cold working, and annealing to ensure superior mechanical strength and corrosion resistance.
2.Product Applications
Marine & Offshore: Seawater lines, condensers, heat exchangers, ballast, firefighting, and cooling systems.
Desalination: Tube bundles and piping for MSF/MED plants.
Oil & Gas: Topside seawater utilities and injection systems on platforms and FPSOs.
Power Generation: Power plant condensers and nuclear auxiliary cooling.
Chemical: Acid/alkali-resistant exchangers, chlor-alkali piping, brine evaporators.
Others: Hydraulic brake lines, aquaculture circulation systems.
3 . Product Advantages
Superior corrosion resistance: Seawater corrosion rate ≤0.025 mm/year; resists pitting, SCC, and erosion-corrosion.
Natural anti-biofouling: Inhibits marine organism attachment, maintaining flow without coatings.
High thermal efficiency: ~50 W/(m·K) for 90/10, outperforming stainless steel in heat exchange.
Excellent workability: Supports cold bending, expanding, TIG/MIG welding; joint corrosion resistance matches base metal.
Lightweight: ~50% lighter than carbon steel, reducing structural loads.
Extended lifespan: Matches the full lifecycle of equipment with proper design.
