Copper Nickel Equal Tee CuNi 70/30 C71500 Butt Weld Fitting Corrosion Resistant Offshore
1. Product Description
The Copper Nickel Equal Tee is a T-shaped pipe fitting with three ports of identical internal diameter. It is mainly used for equal-diameter flow division, flow combination, and branch connection in piping systems. It is commonly made from Copper Nickel 90/10 and Copper Nickel 70/30, offering excellent seawater corrosion resistance, biofouling resistance, and good weldability. The product is usually manufactured by seamless hot-pushing, die forging, or extrusion, followed by solution annealing, pickling, and passivation. It can be produced according to ASTM B466, ASME B16.9, EEMUA 146, EEMUA 234, DIN 86088, or customer drawings.
2. Product Applications
Shipbuilding: Seawater cooling systems, ballast water systems, fire mains, bilge systems, deck drainage systems, and seawater desalination piping.
Offshore Engineering: Seawater lift systems, cooling water distribution systems, and firewater ring mains on offshore platforms, FPSOs, and offshore wind platforms.
Desalination: Feed headers, brine recirculation lines, and product water branch pipes in MSF, MED, and RO systems.
Power Industry: Essential service water systems in nuclear plants, circulating cooling water systems in thermal plants, and auxiliary cooling systems in hydro plants.
Petrochemical Industry: Chloride-containing piping, brine lines, cooling water bypass lines, and heat exchanger connections.
Port and Municipal Engineering: Coastal water supply networks, port firewater systems, aquarium circulating water systems, and cooling water piping for seaside facilities.
3. Product Advantages
Seawater Corrosion Resistance: Low corrosion rate in flowing seawater and chloride media, with good resistance to pitting, crevice corrosion, and stress corrosion.
Biofouling Resistance: Naturally released copper ions help inhibit barnacles, shellfish, and algae, reducing cleaning and maintenance frequency.
Good Weldability: Suitable for butt welding, socket welding, and threaded connection, making field installation convenient and welding quality stable.
Wide Temperature Adaptability: Good toughness at low temperatures and stable strength at elevated temperatures, suitable for a wide temperature range.
Erosion-Corrosion Resistance: Long service life in seawater systems with relatively high flow velocity.
Good Economy: Lower life-cycle cost than titanium and some high-alloy stainless steels in seawater service.
Long Service Life: Suitable for long-term marine service with low maintenance cost.
High Standardization: Dimensions and performance comply with international standards, facilitating design selection, installation, and later maintenance.
4. Product Functions
Equal-Diameter Flow Division: Divides main pipeline flow into two equal-diameter branch lines.
Equal-Diameter Flow Combination: Combines two equal-diameter flow streams into one main pipeline.
Right-Angle Branching: Provides a 90-degree perpendicular branch connection with three identical internal diameters.
Piping Connection: Used as a branch node in piping networks for pipeline extension and direction change.
Flow Transition: Smooth internal surface reduces turbulence and local vortices, ensuring smooth fluid passage.
Standardized Connection: Facilitates standardized piping design, installation, and later maintenance.
