Product Description
CuNi 70/30 Copper Nickel Reducing Tee Socket Weld Forged Fittings ASME B16.5 Class150 Marine Grade
1. Product Description
The Copper Nickel Reducing Tee is a specialized pipe fitting manufactured from CuNi alloys (90/10 and 70/30 grades), designed to connect a larger-diameter main pipeline to two smaller-diameter branch lines in a single compact unit. Its "reducing" geometry means the branch outlets are deliberately sized smaller than the run pipe, eliminating the need for separate reducers at branch points.
Design highlights:
Integral forged/formed construction – no welded seams within the body, ensuring structural integrity.
Precise dimensional control – branch-to-run diameter ratios are customizable per customer requirements (standard ratios: 1/2, 2/3, 3/4, etc.).
End finishing – beveled ends per ASME B16.25 for BW types; square-cut with chamfer for SW types; NPT threads for threaded types.
Surface finish – pickled and passivated to remove surface oxides and enhance corrosion resistance.
2.Product Applications
This fitting is engineered for mission-critical piping systems where reliability under corrosive and high-flow conditions is non-negotiable:
-
Shipboard seawater systems – main engine cooling, auxiliary cooling, fire main, deck wash, and sanitary seawater supplies.
-
Offshore oil & gas platforms – topside seawater lift pumps, firewater ring mains, and process cooling loops.
-
Coastal desalination plants – reverse osmosis (RO) feed lines, concentrate discharge headers, and post-treatment transfer piping.
-
Thermal & nuclear power stations – circulating water systems (CWS) and component cooling water (CCW) circuits.
-
Marine equipment manufacturing – heat exchangers, condensers, and evaporator interconnecting pipework.
Suitable media: Clean & raw seawater, brackish water, demineralized water, steam (low pressure), compressed air, hydraulic fluids, and light hydrocarbon oils.
3. Product Advantages
Compared to ordinary stainless steel (316L) or carbon steel fittings:
-
Longer total life-cycle cost efficiency – despite higher upfront cost, CuNi tees deliver 3–5× longer service life in seawater, reducing replacement frequency and downtime.
-
Superior biofouling resistance – natural copper ion release inhibits barnacle, mussel, and algae attachment, eliminating costly chemical dosing and mechanical cleaning.
-
Excellent weldability – CuNi alloys have good hot-cracking resistance and can be welded using standard TIG/MIG procedures with proper filler (e.g., ERCuNi).
-
Low magnetic permeability – ideal for naval applications requiring non-magnetic materials.
-
Proven track record – over 50 years of field service in global naval fleets and offshore installations.
-
Full traceability – each fitting comes with mill test reports (MTR) and third-party inspection options (DNV, ABS, Lloyd's, etc.).
