Product Description

Cupro Nickel 70/30 Equal Tee UNS C71500 ASME B16.9 Marine Pipe Fitting

1. Product Description

Copper Nickel Equal Tee is a T-shaped pipe fitting with three ports of identical nominal diameter. It is mainly used for 90-degree branch connections in piping systems. The fitting is usually made from copper-nickel alloy UNS C70600 (90/10 Cu-Ni) and UNS C71500 (70/30 Cu-Ni), offering high strength, excellent seawater corrosion resistance, and good weldability. It can be produced by seamless or forging processes and complies with ASME B16.9, ASTM B466/B467, MSS SP-43, and DIN 86086. The surface is normally pickled and passivated. It is suitable for marine, shipbuilding, desalination, and chemical applications.

2. Product Applications

  1. Shipbuilding and marine engineering: seawater cooling systems, ballast water systems, fire fighting mains, bilge and sewage discharge systems.

  2. Offshore oil and gas platforms: seawater lift pipes, equipment cooling lines, firewater ring mains, seawater injection systems.

  3. Desalination plants: intake pipelines, brine circulation, reverse osmosis feed distribution, concentrate discharge.

  4. Power generation: condenser cooling water systems, essential service water, circulating cooling water.

  5. Petrochemical industry: transport of chloride-containing, saline, and weakly acidic media.

  6. Coastal facilities: coastal fire protection, large HVAC systems, marine seawater retrofit projects.

3. Product Advantages

  1. Excellent seawater corrosion resistance: forms a stable protective film in static and flowing seawater; corrosion rate is below 0.025 mm/year in marine environments.

  2. Natural anti-biofouling: continuous release of trace copper ions helps prevent marine organism attachment and growth.

  3. Good weldability: suitable for cold bending and flaring; generally no preheating or post-weld heat treatment required.

  4. High flow velocity resistance: safe operation at seawater velocities up to 3.5 m/s.

  5. Low maintenance and long service life: marine service life can reach 25 years or more.

  6. Good life-cycle economy: higher initial cost than carbon steel, but lower maintenance and longer service life reduce total cost.

4. Product Functions

  1. Flow splitting and combining: three equal openings allow one stream to be divided into two or two streams to be merged into one.

  2. 90-degree branch connection: provides a perpendicular branch in pipeline systems.

  3. Balanced flow distribution: ensures stable flow among the three ports with low pressure loss.

  4. Corrosive media conveyance: suitable for long-term transportation of seawater and other corrosive fluids.

  5. System integrity: maintains structural strength and sealing performance under high-temperature and high-pressure conditions.
