Copper Nickel Pipe

Top Copper Nickel Pipe Manufacturer & Supplier in Mumbai, India. Order high quality copper nickel 90/10 pipe and 70/30 copper nickel pipe


Copper nickel pipe, also called cupro nickel pipe is a tough and corrosion-resistant alloy used in industries that need strong, reliable piping. It's manufactured from a mix of copper and nickel, frequently with other elements like iron and manganese for increased strength. Preston Pipes & Alloys, a trusted name in metal supply, offers a wide range of copper-nickel pipes in grades like 90/10 and 70/30. These grades provide excellent mechanical strength and stability in a high-temperature environment. Pipes made from alloys such as C70600 (90/10) and C71500 (70/30), offer great resistance to seawater and brine making them appropriate for marine situations. As leading copper nickel pipe suppliers, we focus on quality, precision, and long-term performance.


Cupro nickel pipes are known for their anti-corrosive nature, good weldability, and resistance to biofouling. These pipes perform well in both hot and cold temperatures, with low risk of scaling or cracking. It is perfect for heat exchangers, condensers, shipbuilding, offshore oil platforms, and desalination plants. Cuni pipe's strength makes it appropriate for power generation systems where thermal stability is crucial, as well as hydraulic lines in naval ships. Cupro nickel alloy pipe also helps reduce maintenance in piping systems exposed to saltwater, steam or chemicals.


Copper Nickel Pipe

Copper nickel pipes come in different forms, like seamless, welded and fabricated, based on your project needs. Sizes usually range from ½ inch to 24 inches in outer diameter, and they follow standards like, ASTM B466 C70600 and B466 UNS C70600. To maintain uniformity and structural strength, the majority of pipes are manufactured utilizing hot or cold drawing. 90/10 cuni pipe and 70/30 copper nickel pipe are both popular for providing consistent flow, and pressure stability in demanding applications. Their consistent wall thickness, smooth bore and strong construction help extend service life even in aggressive environments.


Before delivery, every copper nickel pipe goes through a full set of quality checks. Tests include hydrostatic pressure, PMI testing, flattening, flaring and eddy current testing. Each pipe meets national and international quality standards. Our team uses strict packaging procedures to prevent damage during transit, such as wooden cases or waterproof covering, depending on the location and customer requirements. Reliable, strong, and built for harsh conditions, our copper nickel pipes stand up to every test.
