Key Features

1. Base Tube Material: C71500 Copper Nickel Alloy

• C71500 is a copper-nickel alloy composed of 90% copper and 10% nickel, known for its outstanding corrosion resistance in seawater, chemical environments, and high-temperature systems.

• This alloy offers excellent resistance to pitting, stress corrosion cracking, and erosion, making it ideal for use in environments exposed to chlorides and high-temperature fluids like those found in marine applications or heat exchangers in chemical processing plants.

• Copper-nickel alloys also offer high thermal conductivity, ensuring efficient heat transfer in industrial heat exchangers and cooling systems.

2. Fin Type: Low Fin Design

• The low fin design increases the surface area available for heat exchange without significantly increasing the size of the tube, making it ideal for space-constrained heat exchangers.

• This design ensures maximum heat transfer efficiency in compact heat exchanger systems, where high-performance heat exchange is required in environments with restricted space.

3. Application: Heat Exchanger, Marine, Chemical Processing

• The C71500 Copper Nickel Steel Seamless Low Fin Tube is widely used in marine heat exchangers, cooling systems, and chemical processing applications.

• Its corrosion resistance to seawater and chemically aggressive fluids, combined with its high thermal conductivity, makes it perfect for seawater cooled systems, furnaces, boilers, and condensers in industries like power generation, desalination plants, and petrochemical industries.
