UNS C71500 CuNi 70/30 Reducing Tee Socket Weld Fitting ASME B16.5 Class 150 Forged Pipe Fittings
1. Product Description
The Copper Nickel Reducing Tee is a high‑performance T‑shaped fitting manufactured from CuNi alloys (90/10 or 70/30). It features one main run outlet and two branch outlets with different diameters, enabling efficient flow distribution and diameter reduction in a single component. As a reducing tee, it smoothly transitions flow from a larger main pipe to smaller branch pipes, minimizing turbulence and pressure drop.
Key functional capabilities:
-
Splits flow from the main line into two branches of smaller size, or combines two branch flows into a larger main line.
-
Provides a permanent three‑way junction with leak‑tight performance.
-
Suitable for high‑velocity and high‑pressure seawater systems, as well as for chemical, oil & gas, and desalination services.
2.Product Applications
These fittings are indispensable in environments requiring high resistance to seawater corrosion and biofouling:
-
Marine & Offshore – seawater cooling, firefighting systems, ballast water, bilge, and sanitary piping.
-
Desalination – intake lines, brine discharge, and product water transfer.
-
Power Generation – condenser cooling water and auxiliary seawater circuits.
-
Oil & Gas – platform topside piping, subsea equipment, and refinery process lines.
-
Industrial & Chemical – heat exchangers, HVAC, and chemical processing plants.
-
Other – aquaculture, shipbuilding, and coastal infrastructure.
3. Product Advantages
-
Exceptional durability – proven service life of over 30 years in seawater with minimal maintenance.
-
Superior anti‑corrosion & anti‑fouling – naturally resistant to marine growth, reducing the need for chemical cleaning.
-
High strength at high velocity – withstands seawater flow up to 5 m/s without erosion damage.
-
Reduced pressure losses – the reducing geometry optimizes flow, lowering turbulence and energy consumption.
-
Versatile joining options – compatible with welding, socket, press, and threaded systems, facilitating installation in new or retrofit projects.
-
100% recyclable – environmentally friendly material with full recyclability.
