Product Description

Low fin tubes fabricated from ASTM B111 C71500 (Copper Nickel Alloy 70/30) are exceptionally well-suited for high-performance heat exchangers, particularly in marine, desalination, and power plant applications. The combination of enhanced heat transfer efficiency and remarkable resistance to corrosion makes these tubes a preferred choice in demanding environments.

Material Characteristics of ASTM B111 C71500

This specification covers seamless copper-nickel alloy tubes. The C71500 alloy, also known as Copper Nickel 70/30, comprises 70% copper and 30% nickel, providing excellent resistance to seawater corrosion, biofouling, and erosion. The alloy also contains small amounts of iron and manganese to enhance overall strength and corrosion resistance.

Low Fins

The fins are integrally formed from the base tube material through a precise rolling or extrusion process, increasing the external surface area for better heat transfer. These integral fins ensure a strong bond with no risk of detachment.

Key Features

1. Enhanced Heat Transfer

Increased Surface Area: The low fins significantly increase the external surface area, facilitating efficient heat transfer between the fluid inside the tube and the external environment.

Improved Thermal Performance: The fins disrupt the fluid boundary layer, promoting turbulence and enhancing the convective heat transfer coefficient.

2. Corrosion Resistance

Superior Seawater Resistance: C71500 Copper Nickel offers excellent resistance to seawater corrosion, making these tubes ideal for marine applications.

Biofouling Resistance: The alloy resists biofouling, reducing maintenance and ensuring long-term performance in seawater environments.

Erosion Resistance: The addition of iron and manganese improves resistance to erosion, particularly in high-velocity water and turbulent flow conditions.

3. Mechanical Robustness

High Strength: The copper-nickel alloy provides good mechanical properties, including tensile and yield strength, ensuring durability and reliability under pressure and thermal cycling.

Durability: The robust construction and inherent corrosion resistance of the alloy ensure a long service life, even in harsh operating conditions.

4. Versatility in Applications

Heat Exchangers: Ideal for shell and tube heat exchangers, air-cooled heat exchangers, and plate heat exchangers, especially in marine and coastal environments.

Desalination Plants: Used in desalination plants to efficiently transfer heat in the process of converting seawater to freshwater.

Power Plants: Suitable for heat exchangers in power plants, where resistance to corrosion and biofouling is critical for long-term operation.

5. Compact Design

Space-Saving: The low fin design allows for a more compact heat exchanger configuration, reducing overall size and weight while maintaining high thermal efficiency.

Cost-Effective: The compact design leads to material and installation cost savings, making these tubes an economical choice for large-scale applications.

Applications

Marine Industry: Shipboard Heat Exchangers, Offshore Platforms
Desalination Plants: Evaporators and Condensers
Power Generation: Condenser Tubes, Feedwater Heaters
Chemical Processing: Corrosive Media Heat Exchangers
HVAC and Refrigeration: Cooling Coils
