Sunflex Metal Industry is pride ourselves on being leading manufacturer, exporter, and supplier of Cu Ni 70/30 Tubes across India and worldwide. We are experts in manufacturing the Cupro Nickel 70/30 Tubes with excellent resistance and erosion-corrosion by solids in seawater flowing which levels up to 3-3.5m/s.

We also manufacture Copper Nickel 70/30 Tubing which was resistant to organic compounds, brine water, salt diluted non-oxidizing acids, etc., Our clients prefer these tubes mainly in seawater piping systems due to its complete resistance towards marine organisms. We can manufacture the tubes by changing their thicknesses and sizes that suitable to the client’s requirements. Our clients prefer these tubes for heat reject and brine heater stages as well as in cooling areas where the applications require high corrosion resistance from both shell and tube side.

Offered Cu Ni 70/30 Seamless Tubes with more resistance and improved strength level than Cu Ni 90/10 Tubes in order to make suitable for more demanding applications. These tubes are widely used in industrial applications like gas processing, pharmaceuticals, condensers and more. Type Cupro Nickel 70/30 Welded Tubes are manufactured with special additions in order to maintain good corrosion resistance which is used in industries such as chemical equipment, heat exchangers, power generation, etc.,

 Moreover, our Cu Ni 70/30 Alloy ERW Tubes are amazingly improved oxidation resistance and stress corrosion resistance. These alloys are used as a part of bilge and weight, sterile, firefighting, pressure driven and pneumatic chiller frameworks.
