Copper nickel pipe fittings are used in various industries, especially in marine and offshore applications, where corrosion resistance and durability are critical. Copper nickel alloys, often designated as Cupronickel, are alloys of copper that also contain nickel and other elements. The most common copper nickel alloys used for pipe fittings include C70600 (90-10 copper nickel) and C71500 (70-30 copper nickel).
Copper Nickel Elbow : Used to change the direction of the pipe in a fluid system. Elbows come in different angles, such as 90 degrees and 45 degrees.
Copper Nickel Tee : Allows for a branch connection in a piping system, forming a T-shaped intersection.
Copper Nickel Reducer : Reducers are Used to connect pipes of different sizes, allowing for a smooth transition in diameter.
Copper Nickel Coupling : Joins two pipes of the same diameter together.
Copper Nickel Cap : Used to close off the end of a pipe, providing protection and sealing the system.
Copper Nickel Cross : Provides a four-way intersection in a piping system, creating equal branches in all directions.
Copper Nickel Stub End : Used with lap joint flanges to create a connection where the flanges can rotate and align.
Copper Nickel Union : Allows for the disconnection and reconnection of pipes without the need for cutting.
These fittings are chosen for their excellent corrosion resistance, high thermal conductivity, and good mechanical properties. Copper nickel alloys are particularly suitable for seawater applications due to their resistance to marine corrosion and biofouling. When selecting copper nickel pipe fittings, it's important to consider the specific alloy, size, and type of fitting required for the intended application. Standard specifications such as ASTM B466 and ASTM B467 provide guidelines for copper nickel pipe fittings.
The best feature of copper nickel is its strong genral resistance to seawater. It has high alloy concentration and that is why it is used as connectors for piping systems in the ship and power generation industry. We have the complete stock of Copper nickel Buttweld pipe fittings available in various size, materials and grades to meet your piping requirements.
