C70600 Pipe also called CuNi 90/10 Pipe, UNS C70600 Pipe, ASTM B466 C70600 Copper Nickel Pipe or Cupro Nickel 90/10 Pipe is ASME B36. 19 M, DIN 86019, EEMUA 144 and MIL-T-16420 copper nickel pipe.C70600 Pipes can stand a test of time, even in the most hostile environments like salty water.The main, wrought copper-nickel alloys chosen for sea water service contain 10 or 30 percent nickel. They also have important additions of iron and manganese which are necessary to maintain good corrosion resistance.C70600 Copper Nickel 10% Alloy is used in applications where resistance to corrosion and stress cracking is important. C70600 Copper Nickel 10% Alloy is known for its moderate strength, weldability and formability.

Key Adventages of ASTM B111 C70600 Copper nickel round tube
Excellent Resistance to Seawater Corrosion
The alloy effectively resists uniform corrosion, pitting, crevice corrosion, and impingement attack caused by high-velocity seawater. This is its most fundamental advantage.
Outstanding Biofouling Resistance
The slow release of copper ions effectively prevents marine organisms (such as barnacles, algae) from adhering to and growing on the inner pipe wall, reducing maintenance needs and maintaining flow efficiency.
Good Workability and Formability
Annealed tubes have high ductility and are easily bent, flared, flanged, and welded, facilitating on-site installation and the construction of complex piping systems.
Superior Resistance to Stress Corrosion Cracking (SCC)
Compared to some other alloys (such as certain stainless steels), 90-10 CuNi has high resistance to stress corrosion cracking in chloride environments, offering greater reliability.
Long Service Life and High Reliability
Its combined corrosion and erosion resistance ensures a very long service life in harsh marine and industrial environments, reducing the total cost of ownership.
CuNi 90/10 Tube Main Applications:
Shipbuilding and Offshore Engineering: Seawater cooling systems, firefighting systems, ballast water systems, bilge water systems, and fuel pipelines on ships.
Offshore Oil and Gas Platforms: Seawater cooling pipes, firewater pipes, water injection pipelines, and various process piping on offshore platforms.
Desalination Plants: Heat exchanger tubes, evaporator tubes, and brine heater tubes in Multi-Stage Flash (MSF) and Multi-Effect Distillation (MED) units.
Power and Energy Industry: Power station condenser tubes and pipelines for handling corrosive fluids in geothermal energy systems.
Chemical and Process Industries: Fabrication of evaporators, heat exchangers, and condensers for handling salt solutions, brines, and other corrosive chemicals.
