CuNi 70/30 Reducing Tee Socket Weld Pipe Fittings Marine Seawater System ASME B16.5 Class150 Custom Size
1. Product Description
The Copper Nickel Reducing Tee is a seamless, T‑shaped fitting manufactured from high‑grade CuNi alloys – 90/10 (UNS C70600) or 70/30 (UNS C71500). It features one main run inlet and two branch outlets of smaller diameters, enabling flow splitting and size reduction in a single component without additional reducers.
The fitting is produced by hot forging or extrusion, ensuring a weld‑free body with superior structural integrity. End connections are available in three types: butt weld (BW) with beveled ends per ASME B16.25, socket weld (SW) with square‑cut chamfered ends, and threaded (NPT or BSP) for screw‑on installation. All surfaces are pickled and passivated to remove oxides and improve corrosion resistance in aggressive media.
2.Product Applications
Commercial vessels and tankers – seawater cooling, fire main systems, ballast water lines, and sanitary piping.
Offshore oil & gas platforms – seawater lift pumps, process cooling loops, and firewater ring mains.
Coastal desalination plants – intake lines, brine discharge headers, and product water transfer.
Power stations (thermal & nuclear) – circulating water systems and auxiliary cooling circuits.
General industrial plants – heat exchangers, HVAC, chemical processing, and compressor piping.
3. Product advantages:
Long service life – proven 30+ years in seawater with minimal corrosion, significantly reducing replacement and maintenance costs.
Natural anti‑biofouling – copper ion release prevents barnacle, mussel, and algae attachment, eliminating chemical dosing and manual scraping.
Erosion resistance – withstands high‑velocity flow up to 5 m/s without surface damage, ideal for pump discharge lines.
Good weldability – compatible with standard TIG/MIG welding using ERCuNi filler, with simple preheat requirements for thicker walls.
Full traceability – each fitting comes with mill test reports, and optional third‑party inspection (e.g., DNV, ABS, Lloyd's) is available.
100% recyclable – environmentally sustainable, meeting green procurement standards.
