Industrial Copper-Nickel Tee

Copper-nickel tees are manufactured from 90/10 or 70/30 copper-nickel alloys, offering excellent resistance to seawater corrosion and biofouling, as well as good weldability. They are specifically designed for branch connections in piping systems carrying seawater, industrial cooling water, and similar fluids. Available in equal-diameter or reducer configurations in accordance with standards such as ASTM and DIN, they are widely used in marine, seawater cooling, and heat exchange systems.

Core Industrial Advantages

Excellent Resistance to Seawater Corrosion: Copper-nickel alloys (particularly 90/10 and 70/30) exhibit extremely low uniform corrosion rates in high-chloride-ion media such as seawater and brackish water, far outperforming carbon steel and ordinary stainless steel, thereby significantly extending the service life of piping systems.

Resistance to Biofouling: Copper ions in the material inhibit the attachment and reproduction of marine microorganisms, reducing pipeline blockages and the need for frequent cleaning and maintenance, making it suitable for long-term submersion in seawater.

Good Resistance to Stress Corrosion and Impact: Compared to austenitic stainless steel, copper-nickel alloys are not susceptible to stress corrosion cracking and maintain excellent ductility and low-temperature toughness.

Excellent Formability and Weldability: The material allows for homogeneous welding, producing high-strength, dense welds. It is compatible with TIG, MIG, and brazing, facilitating on-site installation and maintenance.

Long-term cost-effectiveness: Although the initial material cost is slightly higher, the total life-cycle cost is significantly reduced due to the elimination of coatings, sacrificial anodes, and frequent replacements.
