70/30 CuNi Copper Nickel Reducing Tee Socket Welding Pipe Fitting Corrosion Resistant Marine Offshore Class150
1. Product Description
A Copper Nickel Reducing Tee is a T-shaped pipe fitting manufactured from copper‑nickel (CuNi) alloy, featuring three openings with different diameters. The fitting consists of a main opening (the “run”) and two side openings (the “branches”). As a reducing tee, the branch outlet has a smaller diameter than the run, allowing for smooth flow transition between different pipe sizes.
Common material grades include 90/10 Copper Nickel (UNS C70600 / B10 / CuNi90‑10) and 70/30 Copper Nickel (UNS C71500 / B30 / CuNi70‑30). Connection types available: butt weld (BW), socket weld (SW), press, and threaded.
2.Product Applications
Copper Nickel Reducing Tees are widely used in:
-
Marine & Shipbuilding – seawater cooling, fire main, ballast water, bilge, and main seawater lines.
-
Offshore Platforms – seawater cooling and firefighting water systems.
-
Desalination Plants – intake/outfall, high‑pressure brine, and product water distribution.
-
Industrial – chemical processing, power plants, HVAC, oil & gas.
-
Others – petrochemical, pharmaceutical, aquaculture, and metallurgy.
Suitable media: seawater, fresh water, air, steam, oil, and various chemicals.
3. Product Advantages
-
Superior corrosion resistance – seawater corrosion rate <0.025 mm/year; excellent resistance to biofouling.
-
Long service life – >30 years in seawater with minimal maintenance.
-
High mechanical strength – good ductility and erosion‑corrosion resistance; withstands seawater velocity up to 5 m/s.
-
Smooth flow transition – reducing design reduces pressure loss and turbulence at branch connections.
-
Multiple connection options – BW, SW, press, and threaded to suit various installation needs.
-
Environmentally friendly – natural anti‑fouling reduces chemical usage; 100% recyclable.
