Product Description
CuNi 70/30 Seamless Copper Nickel Pipe ASME SB466 Marine Corrosion Resistant Tube
1.Product Description
Copper Nickel Pipe (also known as Cu-Ni pipe or cupronickel pipe) is a seamless or welded metal piping product made from copper-nickel alloys. The most common grades are 90/10 (90% copper, 10% nickel, UNS C70600) and 70/30 (70% copper, 30% nickel, UNS C71500). These alloys also contain small amounts of iron and manganese, which are essential for maintaining excellent corrosion resistance in harsh environments. Copper nickel pipes are manufactured in both seamless and welded forms, conforming to international standards such as ASTM B466, ASTM B111, ASME SB111, BS 2871, EN 12451, and JIS H3300.
2.Product Applications
Copper nickel pipes are widely used in the following fields:
Marine and Shipbuilding: Seawater cooling systems, bilge and ballast systems, sanitary systems, fire fighting systems, inert gas systems, hydraulic and pneumatic systems, and chiller systems
Seawater Desalination: Desalination plants and water treatment facilities
Heat Exchangers and Condensers: Condensers, coolers, evaporators, and heat exchanger tubes
Offshore Engineering: Offshore oil platforms, FPSO platforms, and marine renewable energy (wind farms, wave and tidal devices)
Power Generation: Power plants, nuclear engineering, and steam superheater systems
Chemical Processing: Chemical process equipment, pulp and paper industry, and food processing
Aerospace: Aircraft ducting systems, jet engine exhaust systems, and thrust-reverser systems
Automotive: Power steering tubes and brake lines
Aquaculture: Fish cages and seawater systems
3.Product Advantages
Excellent Corrosion Resistance: Outstanding resistance to corrosion in seawater, brackish water, and other harsh environments. General corrosion rates in seawater range between 0.025 and 0.0025 mm/year.
Superior Biofouling Resistance: Naturally resistant to marine organisms such as barnacles, algae, and mussels, making it ideal for seawater systems.
High Strength and Durability: Good mechanical strength and ductility at both room and elevated temperatures. Service life can reach up to 50 years in marine environments.
Excellent Thermal Conductivity: Retains the good thermal conductivity of copper alloys, suitable for high-efficiency heat transfer equipment.
Good Weldability and Formability: Easy to weld, bend, and machine. Both alloys are single-phase solid solution alloys that can be strengthened by work hardening.
Resistance to Stress Corrosion Cracking: Virtually immune to stress-corrosion cracking and hot spot denickelification.
Lightweight: Compared to steel pipes, copper nickel pipes allow for reduced overall wall thickness and weight.
Long Service Life: Low maintenance requirements and exceptional longevity in demanding applications.
