Product Description
Copper Nickel 70/30 Equal Tee ASME B16.9 Seamless Buttweld Fitting Seawater
1. Product Description
Copper Nickel Equal Tee is a T-shaped pipe fitting with three ports of equal nominal diameter. It is made of copper-nickel alloy, commonly UNS C70600 (90/10 Cu-Ni) and UNS C71500 (70/30 Cu-Ni). The fitting can be produced by seamless or forging process and is mainly used for 90-degree branch connections in piping systems. It is normally manufactured to ASME B16.9, ASTM B466/B467, MSS SP-43, and DIN 86086. Copper-nickel alloy offers high strength, excellent seawater corrosion resistance, natural anti-biofouling performance, and good weldability. The surface is usually pickled and passivated, making it suitable for marine, shipbuilding, desalination, and chemical applications.
2. Product Applications
Shipbuilding and marine engineering: seawater cooling lines, ballast water systems, fire fighting mains, bilge and sewage discharge systems.
Offshore oil and gas platforms: seawater lift pipes, equipment cooling lines, firewater ring mains, seawater injection systems.
Desalination plants: intake pipelines, brine circulation lines, reverse osmosis feed distribution, concentrate discharge pipelines.
Power generation: condenser cooling water systems, essential service water systems, circulating cooling water systems.
Petrochemical industry: pipelines for chloride-containing, saline, and weakly acidic media.
Coastal public facilities: coastal fire protection systems, large HVAC systems, marine seawater retrofit projects.
3. Product Advantages
Outstanding seawater corrosion resistance: forms a stable protective film in both static and flowing seawater; corrosion rate in marine environments is typically below 0.025 mm/year.
Natural anti-biofouling: trace copper ion release helps inhibit marine organism attachment and growth, reducing cleaning and maintenance.
Good welding and processing performance: suitable for cold bending, flaring, and welding; generally no preheating or post-weld heat treatment required.
High flow velocity resistance: can operate safely for long periods at seawater velocities up to 3.5 m/s.
Long service life: marine service life can reach 25 years or more.
Good life-cycle economy: initial cost is higher than carbon steel, but lower maintenance and fewer replacements reduce total cost.
4. Product Functions
Flow splitting and combining: three equal-diameter ports allow one stream to be divided into two or two streams to be merged into one.
90-degree branch connection: provides a perpendicular branch connection in piping systems.
Balanced flow distribution: ensures stable flow among the three ports with low pressure loss.
Corrosive media conveyance: suitable for long-term transportation of seawater and other corrosive fluids.
System integrity: maintains structural strength and sealing performance under high-temperature and high-pressure conditions.
