Base Tube Material: ASME SB111 C70600 (Cu90Ni10)
C70600 is a copper-nickel alloy containing 90% copper and 10% nickel. This alloy is known for its excellent corrosion resistance, especially in marine and industrial environments. The combination of copper and nickel ensures outstanding thermal conductivity, making it ideal for heat exchangers. C70600 is often used in seawater cooling systems, chemical processing, and other environments where high thermal efficiency and corrosion resistance are critical.
Fin Type: Low Fin Tube
The Low Fin Tube design features low-profile fins that are closely spaced along the tube's surface. These fins significantly increase the surface area for heat exchange, improving the thermal efficiency of the heat exchanger. Low fin tubes are particularly energy-efficient, as they allow for greater heat transfer with lower air-side resistance compared to other fin designs. This design is highly effective in maximizing the heat exchange while saving energy.
Application: Energy Saving for Heat Exchanger
Low Fin Tubes are specifically designed for use in heat exchangers where efficient heat transfer is critical. The Cu90Ni10 alloy offers excellent performance in applications exposed to high thermal stresses and aggressive environments such as seawater, brine, and chemicals, making it an ideal choice for industrial heat exchangers.
