Vipul Pipes and Tubes, Chennai, India, is a reliable manufacturer and supplier of high-quality Copper Nickel Welded Pipes that provide solutions for marine, industrial, and offshore uses. Fabricated with Cu-Ni alloys like 90/10 and 70/30, these welded pipes are renowned for their superior corrosion resistance, thermal conductivity, and durability. With high-end welding methods and quality assurance practices, Vipul Pipes makes sure that every product achieves international standards such as ASTM B467. These pipes are perfect for challenging environments, especially where exposure to seawater, brine, and chemically aggressive media is frequent, making them a safe option for long-term operation.
Copper Nickel Welded Pipes are characterized by Cu-Ni 90/10 (90% Copper, 10% Nickel) or 70/30 (70% Copper, 30% Nickel) alloys. They also contain traces of iron and manganese for enhanced strength and corrosion resistance. The pipes provide tensile strength of 275–500 MPa, yield strength of 105–195 MPa, and elongation of up to 30%. The pipes provide good resistance against pitting, erosion, and stress corrosion cracking. The welded buildup provides structural consistency, which renders them appropriate for both high-pressure and low-temperature use without the loss of integrity.

Copper Nickel Welded Pipes find wide application in marine applications like seawater piping, cooling loops, bilge and ballast lines, and fire fighting systems because of their excellent corrosion and biofouling resistance. They are critical in shipbuilding, desalination plants, and offshore platforms. They work as heat exchangers and condensers dealing in brackish and seawater in power plants. Also, these pipes find application in oil & gas facilities, HVAC systems, and chemical processing industries, particularly where there are coastal or saline environments. Due to their resistance to aggressive media, easy fabrication, and durability, they are a choice for long-term piping solutions.
