CuNi 70/30 Copper Nickel Pipe, also named cupronickel seamless pipe, is a high-performance alloy pipeline product strictly compliant with ASME B16.5 and UNS C71500 industrial standards. Composed of 70% pure copper and 30% nickel alloy, this seamless pipe adopts integral hot forging and seamless rolling technology, eliminating welding seams and structural defects of ordinary welded pipes. The product features uniform material density, smooth inner and outer wall, stable chemical properties and excellent overall toughness. It is a key basic pipeline material for high-standard industrial and marine engineering piping systems, tailored for long-cycle and high-stability fluid transmission scenarios, different from ordinary carbon steel and stainless steel pipes with poor corrosion resistance.

3. Application Scope & Product Function
This 70/30 copper nickel pipe is professionally designed for harsh corrosive and high-pressure working environments. Its core function is to stably transmit seawater, chemical liquid, cooling water and other media without pipeline damage. It is widely used in offshore oil platforms, marine ship piping systems, seawater desalination projects, chemical and petrochemical factories, power plant cooling circulation systems and saltwater industrial pipelines. It effectively solves pipeline rust, corrosion, wall thinning and medium leakage problems caused by long-term contact with saltwater and corrosive chemicals.
4. Product Core Advantages
Excellent Anti-corrosion Performance: The unique copper-nickel alloy formula resists seawater erosion, marine organism adhesion and acid-base corrosion, with a service life 4-6 times longer than ordinary steel pipes.
High Pressure & Temperature Resistance: Integral seamless structure boasts high structural strength, capable of adapting to high-pressure and high-temperature industrial transmission conditions without deformation or cracking.
Smooth Transmission & Low Resistance: Polished inner wall reduces fluid resistance, avoids medium residue and pipeline blockage, ensuring efficient and stable long-term pipeline operation.
Strong Compatibility: Perfectly matched with copper nickel flanges, tees and other pipe fittings, easy for installation and later maintenance.
