Frequently Asked Questions — CuNi 90/10 Pipes
What is CuNi 90/10 pipe and what is it used for?
CuNi 90/10 (UNS C70600) is a copper-nickel alloy pipe containing 90% copper and 10% nickel with small additions of iron and manganese. It is primarily used in marine and seawater applications due to its excellent corrosion resistance in saltwater environments. The alloy offers outstanding resistance to biofouling, stress corrosion cracking, and erosion-corrosion in high-velocity seawater. It is widely specified for offshore oil and gas platforms, desalination plants, naval vessels, and coastal power stations.
What is the difference between CuNi 90/10 and CuNi 70/30?
CuNi 90/10 (C70600) contains 90% copper and 10% nickel, while CuNi 70/30 (C71500) has 70% copper and 30% nickel. The 70/30 grade offers higher strength and better corrosion resistance in aggressive seawater conditions and at higher flow velocities. However, CuNi 90/10 is more economical, easier to fabricate, and sufficient for most standard seawater cooling and piping applications. Creative Metal Industries stocks both grades and can help you select the optimal alloy for your specific service conditions.
Why is CuNi 90/10 preferred for seawater piping systems?
CuNi 90/10 is preferred for seawater piping because it forms a stable protective oxide film that resists corrosion in chloride-rich marine environments. The alloy provides excellent resistance to biofouling, meaning barnacles and marine organisms are less likely to attach to pipe surfaces. It also handles high flow velocities without erosion-corrosion, making it ideal for pump discharge lines and fire-fighting systems. Additionally, it offers good thermal conductivity for heat exchanger applications in marine environments.
How does CuNi 90/10 resist marine biofouling?
CuNi 90/10 has inherent antifouling properties due to the controlled release of copper ions from the pipe surface. These copper ions create an environment that discourages the settlement of marine organisms such as barnacles, mussels, and algae. This natural biofouling resistance reduces maintenance costs and maintains hydraulic efficiency in seawater systems over extended periods. The biofouling resistance improves with continuous seawater exposure as the protective oxide film matures.
What sizes of CuNi 90/10 pipe does Creative Metal Industries supply?
Creative Metal Industries supplies CuNi 90/10 pipes in sizes ranging from 1/2 inch to 12 inch NB (15NB to 300NB) in seamless, welded, and tube forms. We stock schedules from SCH 10S to SCH 80S for seamless pipes and SCH 10S to 40S for welded pipes. Tubes are available from 12.7mm to 114.3mm OD in BWG 14 to 22 wall thicknesses. We also supply matching fittings, flanges, and accessories for complete piping system solutions.
What is the price range of CuNi 90/10 pipe in India?
The price of CuNi 90/10 pipe in India typically ranges from Rs 1,200 to Rs 3,500 per kg depending on size, schedule, form (seamless/welded), and quantity ordered. Seamless pipes in smaller sizes and heavier schedules tend to be at the higher end of the range. Creative Metal Industries offers competitive pricing with direct mill supply for bulk orders.
