Marine Grade Copper Nickel Equal Tee Forged C71500 Socket Weld Class 150
Marine Grade Copper Nickel Equal Tee Forged C71500 Socket Weld Class 150
1. Product Description
This Copper Nickel Equal Tee is manufactured from Cu-Ni 90/10 or 70/30 alloy, with three ports of equal diameter for perpendicular branch connections. It conforms to ASME B16.9, ASTM B467, etc., and is available in seamless or welded types. Ideally suited for seawater, salt spray, and other highly corrosive environments.
2. Product Applications
-
Shipbuilding:Main engine seawater cooling, ballast control, fire main, bilge discharge
-
Offshore:Platform seawater lift, cooling water distribution, splash zone piping
-
Desalination:Raw water intake, brine recirculation, concentrate outfall
-
Chemical:Branch lines for chlorine-bearing or dilute acid media
-
Power generation:Auxiliary cooling & condenser circulating water in nuclear/thermal plants
-
General industry:Coastal fire protection, HVAC chilled water, aquarium high-flow circuits
3.Product Advantages
-
Superior corrosion resistance – Excellent resistance to pitting, crevice & SCC in seawater/chloride media; 3-5× longer life than carbon steel.
-
Anti-fouling – Naturally releases copper ions, preventing barnacles, mussels & algae attachment, greatly reducing cleaning frequency.
-
Good mechanical performance – High strength, good ductility & low-temperature toughness with strong impact resistance.
-
Easy welding – Conventional GTAW/GMAW without preheat or PWHT; stable weld properties.
-
Erosion resistant – Maintains oxide film integrity under reasonable velocity (seawater ≤3 m/s).
-
Cost-effective – Slightly higher initial cost but significantly lower life-cycle cost than carbon steel & ordinary stainless steel.
-
Flexible supply – Full range 1/2″~48″, custom non-standard sizes, three connection types available.
