Copper Nickel 70/30 Pipes are top-notch alloy pipes made up of 70% copper and 30% nickel, celebrated for their outstanding resistance to corrosion in seawater and tough marine conditions. They’re lightweight, durable, and resistant to biofouling, making them perfect for shipbuilding, offshore platforms, desalination plants, and various industrial piping systems. With excellent thermal conductivity and a strong resistance to stress corrosion cracking, these pipes are a reliable choice for heat exchangers, condensers, and seawater piping applications.
These pipes primarily consist of 70% copper and 30% nickel, along with trace amounts of iron and manganese. This unique blend gives them impressive tensile and yield strength, along with high resistance to erosion and corrosion, and good ductility. Mechanically, they showcase exceptional toughness, stability under high pressure, and resistance to pitting and crevice corrosion, ensuring they perform reliably in challenging environments.
