Impex Tube India, Mumbai-based leading supplier and manufacturer, specializes in offering high-quality Copper Nickel ERW (Electric Resistance Welded) Pipes. These pipes are well known for their higher strength, corrosion resistance, and durability, particularly under aggressive environments such as seawater and chemical processing. Impex Tube India makes sure that every Copper Nickel ERW Pipe conforms to tough industry standards through superior manufacturing processes and quality control. Such pipes are commonly found in a broad spectrum of uses, especially on marine, offshore, and industrial applications, which provide dependable, long-lasting piping system performance to critical piping plants.
Copper Nickel ERW Pipes consist of 90% copper and 10% nickel with trace amounts of iron and manganese, which renders them highly resistant to corrosion, especially in seawater. This alloy content imparts superior resistance to biofouling, erosion, and stress corrosion cracking. Copper Nickel ERW Pipes are mechanically good in tensile strength (about 275 MPa) and have high endurance under stress, thus maintaining their structural integrity even under harsh conditions. These pipes also possess good thermal and electrical conductivity and are thus ideal for use in heat exchangers and systems where both corrosion resistance and strength are called for.
