Typically, these pipes consist of 90% copper and 10% nickel (Cu-Ni 90/10) or 70% copper and 30% nickel (Cu-Ni 70/30), with small amounts of iron and manganese added to boost strength and resistance to seawater impingement. The alloy boasts a tensile strength between 275 to 450 MPa, a yield strength of 105 to 180 MPa, and elongation rates ranging from 30% to 45%. The ERW manufacturing process creates a uniform weld bead without the need for filler materials, ensuring consistent mechanical properties and smooth, corrosion-resistant surfaces that optimize fluid flow and performance.
