ASTM B111 C71500 Copper-Alloy Low Fin For Heat Exchangers In Power Plants

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

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

Enhanced Heat Transfer: Increased surface area and improved thermal performance through fin design.

Corrosion Resistance: Superior seawater, biofouling, and erosion resistance.

Mechanical Robustness: High strength and durability for demanding applications.

Versatility: Suitable for various heat exchanger configurations in multiple industries.

Compact Design: Space-saving and cost-effective solution.

Applications

Marine Industry Desalination Plants Power Generation Chemical Processing HVAC and Refrigeration
