New Eagle Industrial Corporation offers premium Copper-Nickel (Cu-Ni) Instrumentation Tubes, engineered to deliver exceptional corrosion resistance, mechanical strength, and durability for demanding industrial applications. Manufactured in compliance with international standards such as ASTM B75, ASTM B68, and ASTM B251, these tubes are ideal for use in chemical, marine, and process instrumentation systems where reliability and long-term performance are crucial.Copper-Nickel Instrumentation tubes, commonly available in grades 90/10 (CuNi 90/10) and 70/30 (CuNi 70/30), provide outstanding resistance to seawater, brackish water, and other aggressive environments. Their inherent anti-fouling characteristics reduce the risk of biofouling in instrumentation lines, ensuring consistent performance over time. The material’s excellent tensile strength and ductility make it suitable for high-pressure instrumentation systems, allowing seamless integration with valves, fittings, and process equipment.Cupro-Nickel Instrumentation Tubes are produced with tight dimensional tolerances, smooth surface finishes, and strict quality control measures to meet project-specific requirements. Available in both seamless and welded configurations, these tubes can be supplied in standard sizes or custom lengths to suit specialized instrumentation systems. Certified for international quality standards.
