Based in Houston, Texas, George Metals is a top producer and supplier of high-grade copper nickel 70/30 pipes for use in offshore, industrial, and marine settings. High-grade 70/30 copper-nickel alloy, which is used in the engineering of our pipes, provides exceptional strength and corrosion resistance, particularly in harsh brine and seawater environments. These pipes, which are made to international standards, guarantee outstanding weldability, long-term durability, and dependability in high-pressure and high-temperature environments. George Metals is dedicated to providing precisely engineered Copper Nickel 70/30 Pipes that satisfy the requirements of vital systems in the chemical processing, power generation, desalination, and shipbuilding sectors.
About 70% copper and 30% nickel make up copper nickel 70/30 pipes, with trace amounts of iron and manganese added to increase strength and resistance to corrosion. This alloy guarantees flexibility and durability with its high tensile strength, which normally ranges between 350 and 550 MPa, and excellent elongation values up to 30%. In high-velocity seawater, the 70/30 composition offers exceptional resistance to pitting, stress corrosion cracking, and erosion. It is perfect for use in heat exchangers, condensers, and other pressure-based fluid handling systems because of its exceptional thermal conductivity and stability at high temperatures.
