Copper Nickel ERW Pipes are primarily composed of alloys like Cu-Ni 90/10 (90% Copper, 10% Nickel) or 70/30 (70% Copper, 30% Nickel), with minor additions of Iron and Manganese to boost strength and corrosion resistance. These pipes excel in resisting saltwater, erosion, and biofouling. In terms of mechanical properties, they offer tensile strength ranging from 310 to 520 MPa and yield strength from 100 to 250 MPa, depending on the specific grade. With impressive elongation (up to 40%), thermal stability, and excellent weldability, Cu-Ni ERW pipes are designed to perform reliably in high-pressure, high-temperature, and corrosive environments.

Copper Nickel ERW Pipes are extensively utilized in marine and industrial systems where both corrosion resistance and strength are crucial. They play vital roles in seawater cooling systems, fire protection systems, ballast lines, bilge systems, and hydraulic piping in shipbuilding. Additionally, these pipes are essential in offshore oil platforms, desalination plants, and power generation facilities, particularly in heat exchangers and condenser tubing. Their outstanding thermal conductivity, anti-fouling characteristics, and resistance to stress corrosion make them ideal for continuous exposure to seawater and aggressive fluids.
