Ojas Pipes and Tubes stands out as a reliable manufacturer and supplier of Copper Nickel Welded Tubing right in Kolkata, India. We pride ourselves on delivering high-quality, corrosion-resistant tubing that’s perfect for both marine and industrial uses. Our copper-nickel welded tubes are designed to offer excellent thermal conductivity along with top-notch resistance to seawater corrosion, making them a great fit for tough environments. Adhering to international standards like ASTM B466 and ASTM B751, these tubes ensure consistent dimensions, solid weld integrity, and a long lifespan. We cater to various industries, including marine engineering, power plants, and chemical processing, providing dependable tubing solutions tailored to meet our customers’ needs.
When it comes to composition and mechanical properties, Copper Nickel Welded Tubing typically consists of Copper (90–70%) and Nickel (10–30%), with small amounts of iron and manganese added to boost strength and corrosion resistance. Popular grades include CuNi 70/30 and CuNi 90/10. These tubes showcase impressive tensile strength ranging from 300–450 MPa, yield strength between 100–350 MPa, and elongation of 15–40%, depending on the specific alloy and processing. The welded construction guarantees structural integrity and consistent mechanical performance, while also providing excellent resistance to biofouling, erosion, and stress corrosion cracking, particularly in seawater and brackish water settings.
