Adinox Overseas is a worldwide renowned producer and exporter of high-quality Copper Nickel 90/10 Tubes, which are designed to the highest industry standards and toughest working conditions. Also referred to as UNS C70600, the alloy consists of 90% copper and 10% nickel with minor but important contents of iron and manganese added to improve its corrosion resistance, in particular in seawater and marine applications. These tubes are produced to the requirements of ASTM B466, which lays down the requirements of seamless copper-nickel tubes and pipes for general engineering applications, heat exchangers, and condensers.
The superior resistance of Cu-Ni 90/10 Tubes to corrosion in seawater, biofouling, and stress corrosion cracking renders them the industry's go-to option in shipbuilding, offshore oil and gas, desalination, chemical processing, and power generation. Seamless and welded Copper Nickel 90/10 tubes offered by Adinox Overseas are tested to perform consistently even in varying temperature and pressure conditions. These tubes possess superior thermal conductivity, good strength in tension, and optimal fabricability.
Adinox Overseas also provides Cu-Ni 90/10 Welded Pipes, a cost-effective option for low and medium pressure systems. They are commonly used in fire suppression and refrigeration and HVAC applications owing to their easy installation, high durability over the years, and superior mechanical behavior. Whether you require standard sizes or custom specifications and lengths, our production facility enables us to produce what your job requires exactly.
The UNS C70600 boasts superior mechanical and metallurgical properties to function well in both turbulent and static marine conditions. These Copper Nickel 90/10 Tubes provide a good combination of corrosion resistance and strength to suit applications in cooling loops, heat exchangers, condensers, ballast systems, as well as for firewater systems in the off shore. They prevent the development of micro-organisms and algae due to their natural antimicrobial properties as well, ensuring efficient working over a long period of time.
With superior resistance to impingement and erosion attacks by high-pressure seawater, our UNS C70600 Tubes are made to last in the most corrosive conditions. Iron added to them develops their strength, while manganese adds their weldability and resistance to stress corrosion cracking. They are highly formable, weldable, and convenient to install, thus saving maintenance downtime and ensuring cost-effectiveness for extended industrial applications.
