Cupro Nickel Tube is a strong, corrosion-resistant alloy made mainly of copper and nickel, designed for harsh marine and industrial environments. This tube has good resistance to high temperatures, biofouling, and seawater corrosion. Preston Pipes & Alloys is a reliable copper nickel tube manufacturer in India. We supply high-quality copper nickel tubes in both 90/10 and 70/30 grades. It is built to meet global industry standards. As one of the leading cupro nickel tube suppliers, we provide options that meet various mechanical needs, including high tensile strength, excellent ductility and reliable pressure handling. Our products are trusted in a variety of industries due to their effectiveness and dependability.
Cupro nickel tubes stand out for their thermal stability, anti-corrosive properties, and long service life. These features make them ideal for heat exchangers, condensers, offshore oil rigs, and shipbuilding. CuNi tube performs well in saltwater systems, making it a popular choice in marine construction. Our 90-10 copper nickel tube is extensively used for desalination plants and cooling systems, while the 70-30 copper nickel tube is used for more demanding situations such as power plants and chemical processing units. These tubes hold up under pressure and temperature, delivering performance where it matters most.
We provide a wide selection of specs to accommodate various projects and conditions. Copper nickel tubes are available in both seamless and welded forms, with sizes ranging from small-diameter coils to large industrial lengths. The tube is manufactured utilizing controlled hot or cold working procedures to maintain uniform structure and quality. Whether the application requires straight lengths or coiled shapes, our tubes are made with tight tolerances for easy integration. Each batch meets international standards for dimensional accuracy and strength, ready to perform in critical systems.
All Cupro Nickel Tube products undergo strict quality checks before dispatch. We use hydrostatic testing, eddy current testing, and visual inspections to assure product integrity. We also perform chemical and mechanical analysis on each batch. Each copper nickel tube is packed using protective wrapping, end caps, and wooden crates, to avoid damage during transport. With a focus on reliability, safety, and long-term performance, we deliver tubing that exceeds expectations. Reach out now to get dependable copper nickel tube solutions built for your industry.
