This product is a butt-welding reducing tee manufactured from UNS C70600 (90/10 Copper-Nickel alloy) in accordance with ASTM B466 and ASME B16.9 standards . Also known as CuNi 90/10 or Werkstoff Nr. 2.0872, this alloy offers an excellent balance of corrosion resistance, strength, and cost-effectiveness . This 2" Schedule 80 fitting is designed for permanent, leak-proof butt-weld connections in demanding piping systems .

This reducing tee is ideal for seawater and corrosive fluid systems :
Marine & Shipbuilding: Seawater cooling systems, firefighting pipelines, ballast systems, bilge lines
Offshore Oil & Gas: Seawater injection systems, heat exchangers
Desalination Plants: Brine heaters, condenser tubing
Power Generation: Condensers, cooling water systems
Coastal Infrastructure: Harbor facilities, sewage outfalls
Superior Corrosion Resistance: Exceptional resistance to seawater corrosion, pitting, crevice corrosion, and stress corrosion cracking
Biofouling Resistance: Forms a protective oxide layer that resists marine biological fouling
Cost-Effective: Offers a favorable balance of performance and budget compared to titanium or super duplex grades
Good Weldability: Readily weldable using standard processes
Non-Magnetic & Low Maintenance: Ideal for subsea and buried systems where access is difficult
The reducing tee connects three pipe sections in a T-shaped configuration, enabling fluid to be divided from a larger main pipe (run) into a smaller branch pipe, or combined from a smaller branch into a larger main line . It provides a permanent, leak-proof junction for transitioning between different pipe sizes in the distribution network.
Preparation: Degrease and clean pipe ends, tee weld areas, and filler metal of oil, grease, and oxidation .
Alignment: Accurately align the tee with connecting pipes ensuring proper fit-up. Reduce branch connects to smaller pipe.
Welding: Use TIG (GTAW) process with matching ERCuNi filler wire (AWS A5.7). Use 100% argon shielding gas. Keep heat input under control.
Post-Weld Cleaning: Clean with stainless steel brush to leave a bright finish. No post-weld heat treatment is required .
Stress Control: Minimize residual stresses as any stress can cause intergranular penetration and severe stress cracking .
Crater Sensitivity: Stops/terminations are sensitive to crater pits – always taper current off and grind all stops .
Cleanliness: Requires a higher degree of cleanliness than for steel fabrication .
Temperature Limit: Avoid use above 300°C to prevent degradation .
Standard delivery time is typically 15–30 days, subject to order quantity and specification availability.
Common international payment methods include T/T (Telegraphic Transfer) and L/C at sight (Letter of Credit) .
Products are securely packed in plywood cases or wooden crates with internal cushioning to ensure safe transportation and prevent damage during transit .
All products undergo strict quality inspection before shipment.
In case of quality issues, retain original packaging and provide relevant photos or third-party inspection reports.
Specific return, exchange, and warranty terms are subject to the final sales contract agreement.
