CuNi 70/30 Copper Nickel Equal Tee ASME B16.9 1/2"-24" for Marine Shipbuilding

Product Specification

CuNi 70/30 Copper Nickel Equal Tee ASME B16.9 1/2"-24" for Marine Shipbuilding

1. Product Description

The Copper Nickel Equal Tee is a high-quality pipe fitting used for branch connections in piping systems, precision-manufactured from copper-nickel alloy (Cu-Ni 90/10 or Cu-Ni 70/30). This fitting features three ports—two inline openings forming the straight-through path called the "run," and one perpendicular opening called the "branch"—with all three ports of identical diameter, hence the name "Equal Tee." The product is available in various manufacturing forms including seamless, welded, and fabricated types to meet the installation requirements of different industrial scenarios. Manufactured in strict compliance with international standards such as ASME B16.9, ASTM B122/B466/B467, these tees are widely used in marine engineering, shipbuilding, chemical pipelines, desalination plants, and other harsh, corrosion-prone environments.

2. Product Applications

Copper Nickel Equal Tees are primarily used for branch connections and flow splitting in piping systems. Key application areas include:

• Marine Engineering & Shipbuilding: Seawater cooling systems, ballast water systems, fire water lines, bilge systems

• Offshore Oil & Gas Platforms: Seawater transmission lines, cooling water systems, fire water systems, splash zone protection

• Desalination Plants: Corrosion-resistant piping connections for seawater treatment

• Chemical & Petrochemical Industry: Acid/alkali medium transmission lines, corrosive fluid systems

• Power Plants (Nuclear/Thermal): Cooling water circulation systems, auxiliary pipelines

• Construction & Fire Protection: Fire sprinkler systems, HVAC water systems

• Other Industrial Fluid Transmission: Fresh water, air, steam, and oil medium pipelines​

3.Product Advantages

1. Superior Seawater Corrosion Resistance: Copper-nickel alloys offer exceptional resistance to seawater, brine, and chloride-containing media, with pitting resistance and stress corrosion cracking resistance far superior to carbon steel and ordinary stainless steel, extending service life by 3-5 times.

2. Excellent Biofouling Resistance: The surface of copper-nickel alloy effectively inhibits marine organism attachment and growth, reducing pipeline blockage and maintenance costs.

3. Excellent Mechanical Properties: Combines high strength, good plasticity, and low-temperature toughness, suitable for high-pressure and demanding temperature conditions.

4. Superior Workability: Copper-nickel alloys exhibit good weldability and can be joined using various welding processes such as GTAW and GMAW without complex preheating or post-weld heat treatment requirements.

5. Comprehensive Specifications & Custom Flexibility: Wide size range (1/2″ to 48″) with custom-shaped fittings available according to customer drawings, meeting complex piping layout requirements.

6. International Standard Certification: Products comply with multiple international standards and hold ISO 9001 quality system certification, ensuring reliable quality.
