Our 70/30 Cupro Nickel Tubes have best service life under the most adverse Conditions because of their Improved Corrosion resistance and excellent Stress Corrosion. These 70/30 Cupro Nickel Tubes are used in those applications where severe erosion and corrosion are normal, especially at Elevated Temperatures. Our 70/30 Cupro Nickel Tubes are available in different Outside Diameters, Wall Thicknesses and Tempers to meet the Requirement.
