CuNi 70/30 Heat Exchanger Tube ASTM B466 C71500 Seamless Copper Nickel Pipe
1.Product Description
Copper-nickel pipe is a wrought alloy tube made from a solid solution of copper and nickel, often with controlled additions of iron and manganese. It is manufactured by either seamless extrusion or longitudinal welding from strip coils. Known for its distinctive reddish-silver appearance, this pipe offers a unique combination of high ductility, excellent thermal conductivity, and outstanding resistance to impingement corrosion in turbulent or high-velocity water.
2.Product Functions
Shipbuilding: Main seawater intake lines, sanitary drains, and bilge and ballast systems.
Desalination plants: Evaporator tubing and brine heater pipes.
Offshore platforms: Fire main ring lines and hydraulic control lines.
Industrial refrigeration: Condenser and evaporator coils in ammonia systems (dried ammonia only).
Aerospace: Fuel and hydraulic fluid lines for aircraft (limited use).
3.Product Advantages
Superior erosion-corrosion resistance – Handles water velocities up to 4.5 m/s (15 ft/s) without damage.
Excellent weldability – No preheating needed; maintains nearly full strength after welding.
Low magnetic permeability – Suitable for use near compasses or sensitive electronic equipment.
Good resistance to hydrogen embrittlement – Safe for applications involving wet hydrogen sulfide.
Recyclable and eco-friendly – 100% recyclable with no loss of properties.
