Copper Nickel EFW Pipes are essentially constructed with Cu-Ni alloys like 90/10 (90% Cu, 10% Ni) and 70/30 (70% Cu, 30% Ni) with minor additions of iron and manganese to enhance strength and resistance to corrosion. Copper Nickel EFW Pipes have good mechanical strength with tensile strength of 275–500 MPa, yield strength of 105–195 MPa, and high elongation (up to 30%). EWF process guarantees the uniform weld seam, offering high structural stability. Due to their high resistance to seawater, erosion, and stress corrosion, they are applicable for important fluid transport.

Copper Nickel EFW Pipes are extensively applied in marine processes like seawater cooling, bilge, ballast, and fire fighting systems due to their excellent corrosion and biofouling resistance. They play an important role in desalination plants, heat exchangers, and power plants for brine and high-temperature fluid handling. In the oil and gas industry, these pipes are used for offshore platforms and process piping subject to saltwater environments. They are also weldable and durable enough to be used in chemical processing, shipbuilding, and HVAC systems, where consistent fluid flow and extended service life under corrosive conditions are required.
