Copper Nickel Pipe

Cuni 90/10 Seamless Tube and 70/30 Condenser Tubing supplier in India

Copper-nickel or cupronickel is an alloy of copper, which contains a high concentration of manganese, copper, iron, and nickel. The Copper Nickel Pipe is designed with superior strength and excellent corrosion resistance properties. These pipes can be machined and fabricated easily. They possess superior mechanical properties and can be elongated by 20%. The Copper Nickel 90/10 Pipe is made with 90% of copper and 10% of nickel. This is the most used grade while producing pipes of this grade. They are used in offshore oil and gas refining along with naval systems. In the Copper Nickel 70/30 Pipe, 30% of nickel is present along with 70% copper concentration. This grade shows high thermal resistivity along with excellent oxidation resistance at high temperatures. The Cupro Nickel Pipe is highly versatile and is a preferred choice in marine environments. These pipes are also used in power generation, desalination, seawater piping systems, and so on. We are the leading Copper Nickel Tubes manufacturers in India. Our institution aims at producing high-quality products, which are available at feasible rates.

Copper Nickel Pipe

The Cu-Ni Seamless Tubes are produced with the help of a hot billet. These tubes are formed without any joints or seams. They possess superior strength and exhibit exceptional dimensional accuracy. This Copper Nickel Seamless Tubing has a tensile strength between 43900psi to 60000 psi and yield strength in the range of 16000psi to 57000 psi. These tubes can be availed in different shapes and sizes. The ASME SB552 Welded Cu-Ni Tubes are produced by welding pieces of sheet or coil steel together. These tubes are cost-efficient having a long service life. They are available in Schedules from sch 5 to sch 160. A Copper Nickel Finned Tube are simple tubes, which are made with fins. These fins help increase the contact area with the outer fluid especially, in heat exchangers. The CuNi finned tubing possesses superior fatigue strength along with general strength. These tubings can be annealed or galvanized to provide better corrosion resistance properties. We are the Copper Nickel Pipe manufacturers who can customize all your products in different chemical make-up, shapes, and sizes as per your requirements.

The ASTM B466 Copper Nickel Tube has good ductility and possesses a hardness of 69 Rockwell. These tubes are available in single random, double random, and customized sizes. The Copper Nickel Condenser Tubes are used in condensing process fluids outside. These tubes are widely used in refrigerators, heat exchangers, chillers, surface condensers, and other refrigerants. Copper Nickel U-Bend Tube can be used in various plumbing applications. The bend prevents sewage water from entering the main pipelines. They also help to prevent clogging within the system. All our products including, the Cuni Tubing, are produced following all national and international standards. Our experienced workers make use of the latest technology and the best raw materials whilst producing the best products in the market. If you have any queries or want to get a quote on our products, feel free to contact us.
