ASTM B122 / ASME SB122 / Copper Nickel 90/10 , Cupro Nickel 70/30
Copper Nickel 70/30 is an alloy comprising 70% copper and 30% nickel, renowned for its excellent resistance to corrosion in seawater and other aggressive environments. This alloy combines good mechanical properties with high thermal and electrical conductivity, making it ideal for marine applications such as shipbuilding, offshore structures, and seawater piping systems. Copper Nickel 70/30 is also used in chemical processing, desalination plants, and various industrial applications where durability, reliability, and resistance to biofouling are crucial.
Copper Nickel 90/10 elbows and tees are essential fittings crafted from an alloy comprising 90% copper and 10% nickel, prized for their exceptional corrosion resistance in marine environments. Cu-Ni 70/30 Elbows allow for directional changes in piping layouts, ensuring efficient fluid flow, while Cupro-Nickel 70/30 tees facilitate branching connections for distribution or merging of fluid streams. Their ability to withstand biofouling and maintain mechanical integrity over extended periods makes Copper Nickel 90/10 elbows and tees vital components for ensuring reliable operation and longevity in demanding marine applications.
Manufacturing Copper Nickel 70/30 pipe fittings involves specialized equipment tailored to handle the alloy's properties effectively. The process begins with furnaces for melting and alloying copper and nickel into the desired 70/30 composition. Extrusion machines then shape seamless fittings from heated billets, while hydraulic presses forge fittings from hot-rolled or extruded material. Welding machines are used for joining components in welded fittings, and machining tools such as lathes and drills ensure precise shaping and finishing. Heat treatment furnaces are employed to anneal or temper fittings for optimal mechanical properties. Testing equipment, including dimensional gauges and non-destructive testing tools like ultrasound and X-ray machines, verifies compliance with stringent standards before fittings are finalized for marine, chemical processing, and other applications requiring robust corrosion resistance and durability.
