Copper Nickel Pipe (CuNi 90/10 & 70/30)

Product Description

Our Copper Nickel Pipes, primarily available in the popular CuNi 90/10 (90% Copper, 10% Nickel) and CuNi 70/30 (70% Copper, 30% Nickel) alloys, are the premier choice for demanding marine and industrial applications. Renowned for their exceptional resistance to seawater corrosion and biofouling, these pipes offer a superior combination of durability, thermal conductivity, and mechanical strength. Manufactured to strict international standards (ASTM B466/B467), they provide a reliable, long-lasting solution for fluid transport in harsh environments, ensuring low maintenance costs and extended system life.

Product Specifications (Key Parameters)

Product Applications

1. Shipbuilding & Marine Engineering: Used extensively for seawater cooling systems, bilge and ballast lines, fire mains, hydraulic lines, and sanitary systems.

2. Offshore Oil & Gas: Ideal for platform piping, heat exchanger tubing, and splash zone applications due to high corrosion resistance.

3. Desalination Plants: Critical component in multi-stage flash distillation and reverse osmosis systems for handling high-temperature brine.

4. Power Generation: Utilized in steam turbine condensers and auxiliary cooling systems where fresh water is scarce.

5. Industrial Hydraulics: Preferred material for high-pressure hydraulic lines in corrosive environments.

Product Advantages

1. Superior Corrosion Resistance: Provides long-term, reliable protection against seawater, brackish water, and various industrial chemicals, drastically reducing failure rates.

2. High Flow Efficiency: The smooth interior surface maintains low friction loss, ensuring consistent flow rates and reducing pumping energy costs over time.

3. Low Maintenance Lifecycle: The inherent durability and anti-corrosion properties minimize the need for repairs or replacements, offering a lower total cost of ownership compared to standard carbon steel.

4. Anti-Biofouling Properties: The copper-rich surface naturally inhibits the attachment and growth of marine organisms (biofouling), maintaining flow efficiency and reducing cleaning cycles.

5. Excellent Weldability & Fabrication: Can be easily welded, brazed, or soldered using standard techniques, allowing for complex system designs and secure, leak-proof joints.

Product Functions

1. Efficient Fluid Transport: Engineered to safely convey seawater, potable water, and process fluids under high pressure and flow velocity.

2. Heat Transfer Medium: Functions effectively as tubing in condensers and heat exchangers, leveraging high thermal conductivity for optimal energy exchange.

3. Vibration Dampening: High ductility allows the pipe to absorb mechanical vibrations and shock loads in marine propulsion systems without fracturing.

4. System Integrity Assurance: Maintains structural stability and leak-proof performance in critical applications, ensuring the safety and reliability of the entire piping system.

5. Biofouling Prevention: Acts as a passive defense mechanism, continuously releasing copper ions to create a surface hostile to barnacles and algae
