Product Description

CuNi 70/30 Copper Nickel Equal Tee C71500 Corrosion Resistant Weldable Marine Fitting

 

1. Product Description

The Copper Nickel Equal Tee is a pipe fitting with three identical branch openings of equal internal diameter, designed for equal-diameter branch connections in piping systems. Manufactured from copper-nickel alloy, typically CuNi 90/10 or CuNi 70/30, by precision die forging or seamless tube extrusion, it conforms to international standards including ASTM B466, ASME B16.9, EEMUA 146, and DIN 86088. The copper nickel equal tee offers excellent seawater corrosion resistance, good weldability, thermal stability, and superior erosion resistance.

2. Product Applications

  1. Shipbuilding and Offshore: Seawater cooling systems, ballast water treatment inlets and outlets, fire mains, bilge branch lines, seawater intake lines.

  2. Offshore Oil and Gas Platforms: Seawater lift pump outlet manifolds, platform firewater ring mains, cooling water distribution systems.

  3. Desalination: RO feed header branches, brine recirculation lines, product water transmission piping.

  4. Chemical and Petrochemical: Chlorine-containing wastewater pipes, cooled brine lines, heat exchanger cooling water bypass lines.

  5. Power Industry: Essential service water in nuclear plants, circulating cooling water in thermal plants, auxiliary cooling in hydro plants.

  6. Municipal Engineering: Beach water supply, port firewater systems, aquarium life support piping.

3. Product Advantages

  1. Excellent Seawater Corrosion Resistance: Corrosion rate below 0.03 mm/year in chloride media, with outstanding resistance to pitting, crevice corrosion, and stress corrosion.

  2. Inherent Biofouling Resistance: Naturally releases copper ions, preventing barnacles, oysters, and algae attachment; fouling rate over 60% lower than 316L stainless steel, significantly reducing pipeline cleaning frequency.

  3. Good Workability and Weldability: Can be cold or hot bent; no hardening cracks during welding; suitable for field installation.

  4. Wide Temperature Range Adaptability: Maintains good toughness at -40°C; no significant strength loss at 300°C.

  5. Corrosion Fatigue Resistance: High fatigue life under cyclic stress and corrosive media.

  6. Excellent Cost-Performance: In seawater service, total life-cycle cost is much lower than titanium and super austenitic stainless steel.

  7. Long Service Life: Service life of 25+ years in marine environments.

4. Product Functions

  1. Equal-Diameter Flow Division or Combination: Divides main fluid equally into two branch lines, or combines two equal-diameter fluid streams into one main pipeline.

  2. Right-Angle Branch Connection: Provides a 90° perpendicular branch outlet, with all three ports having identical internal diameters, suitable for equal-diameter branch junctions.

  3. Flow Transition: Smooth internal wall transition ensures turbulence-free and vortex-free fluid passage with reasonable pressure drop.

  4. Piping System Connection: Serves as a critical connection fitting in piping networks, enabling flow direction changes and branch extensions.
