Description：
Our Copper Nickel Alloy Pipe is a high-performance seamless tube renowned for its excellent corrosion resistance in marine environments. Available in C70600 (90/10) and C71500 (70/30) grades, the pipe complies with ASTM B466, ASME SB466, and GB/T 8890 standards. It is ideal for critical applications including shipbuilding, seawater cooling systems, desalination units, and heat exchangers. The pipe exhibits high strength, good thermal conductivity, and outstanding resistance to impingement attack and biofouling .
Application：
Marine Engineering & Shipbuilding: Copper-nickel alloy pipes are extensively used in naval architecture and offshore engineering due to their unparalleled resistance to seawater corrosion and biofouling . They serve as the preferred material for seawater cooling piping systems, condensers, and heat exchangers on ships and offshore platforms. The alloy’s resistance to impingement attack makes it highly suitable for high-flow seawater applications, significantly outperforming standard steel materials .
Power Generation: In thermal and nuclear power plants, these pipes are utilized in critical heat exchange equipment, such as turbine condensers, oil coolers, and auxiliary cooling systems . Their stable thermal conductivity and resistance to stress corrosion cracking (SCC) ensure long-term reliability under demanding operational conditions.
Industrial & Chemical Processing: With excellent resistance to various corrosive media (including dilute acids and alkalis), CuNi pipes are ideal for chemical processing equipment, hydraulic lines, and firewater systems on offshore rigs . They are also employed in the desalination industry for distiller tubing, where they effectively handle harsh saline environments .
Strategic Equipment: These pipes are critical in high-end manufacturing sectors, including aerospace, nuclear engineering, and LNG transmission . Their ability to withstand extreme temperatures (from cryogenic levels to 300°C) without embrittlement makes them versatile for complex systems .
