C70600 marine copper-nickel pipe and tube supplied in accordance with ASTM B111 and ASTM B466 standards for shipboard seawater piping, heat exchangers, ballast water systems, desalination plants, and offshore engineering applications.

Marine-grade C70600 copper nickel pipe features an ultra-low corrosion rate of <0.025 mm/year, natural resistance to marine biofouling, tensile strength of ≥275 MPa, and excellent weldability.

C70600 copper-nickel seamless pipes have long been used in marine systems—such as seawater cooling, fire-fighting, ballast, bilge, condenser, and heat exchange—due to their excellent corrosion resistance, resistance to biofouling, and good machinability a
