WHAT ARE COPPER NICKEL PIPES AND TUBES?

Copper Nickel Pipes are wrought alloys, combining the robust properties of copper and nickel. This unique composition offers exceptional corrosion resistance, remarkable strength, and impressive machinability. Copper Nickel Pipes excel in marine applications due to their outstanding corrosion resistance. They also perform admirably in cryogenic conditions.

Copper Nickel Tubes are available in various types and specifications, including Copper Nickel 90/10 Pipes and Tubes, as well as Carbon Steel Pipes, offered in both seamless and welded constructions.

These products are indispensable in applications like seawater tube work, heat exchangers, hydraulic lines, marine and offshore oil and gas operations, as well as industrial uses such as evaporators, heat exchangers, and chillers.

Copper Nickel Pipes and Tubes offer a wide range of options to suit various pressure requirements. For low-pressure applications, Schedule 40 Copper Nickel Pipes and Alloy 20 Tubes are ideal choices. In contrast, when high-pressure performance is needed, Schedule 80 Copper Pipes step in to handle the task.

To ensure quality and reliability, ASTM B111 lays out precise testing methods for copper nickel pipes and tubes. This standard also defines critical parameters such as diameter, wall thickness, and length, providing a clear guideline for manufacturing and quality control.

SA179 Tubes stands as a leading name in the industry, recognized as a top-tier manufacturer, supplier, and exporter of Copper Nickel Pipes. Our commitment to excellence is evident through our use of premium raw materials, ensuring that our products meet the highest standards of durability and longevity.

Copper Nickel Tubes represent a remarkable copper-nickel alloy with exceptional corrosion resistance. This alloy finds its applications in marine hardware, where exposure to harsh saltwater conditions demands resilience. Additionally, it is a preferred choice for propellers and crankshafts, underlining its versatility across different industrial domains.

We are dedicated to providing top-tier customer service, fulfilling the resource requirements of each customer. With a rich 30-year history in the industry, we have garnered comprehensive hands-on experience in every facet of this field.

We operate as a multifaceted entity, serving as both a manufacturer, supplier, and exporter of ASTM B466 compliant Copper Nickel Pipes. This ASTM grade outlines the specifications for seamless copper nickel pipes, often referred to as CuproNickel pipes, designed for a wide range of general engineering applications.

Our Copper Nickel 90/10 Pipes are particularly suited for light-duty condensers, evaporators, and sugar-making factories. They boast high fabricability and exceptional resistance to oxidation in moist environments.

The Copper Nickel UNS C70600 Seamless Pipes in our lineup offer a remarkable balance of thermal stability and moderate strength. They are characterized by excellent resistance to stress corrosion cracking, ensuring reliability in demanding conditions.

ASTM B466 Copper Nickel and UNS C71500 Welded Pipes exhibit exceptional resistance to biofouling in brackish waters and high-velocity seawaters, making them an invaluable asset in seawater piping systems.
