Description

ASTM B111 C70600 Copper Nickel Steel Low Fin Tube For Hear Exchanger

Product Overview

The ASTM B111 C70600 Low Fin Tube is manufactured from 90/10 copper–nickel alloy (Cu ~88.7–90.0%, Ni ~9.0–11.0%). Low fins are integrally rolled from the tube’s outer surface, enhancing external surface area while keeping the inner surface smooth for fluid flow. This makes it ideal for marine, offshore, and industrial heat exchangers where seawater or brackish water is the cooling medium.

Applications

  • Seawater-cooled heat exchangers in power plants

  • Desalination equipment

  • Shipboard condensers & coolers

  • Petrochemical processing heat exchangers

  • Offshore oil & gas cooling systems

  • HVAC condensers in corrosive coastal environments

Advantages

  • Excellent seawater corrosion resistance due to 90/10 Cu-Ni alloy

  • High resistance to biofouling compared to stainless steels

  • Improved heat transfer efficiency with low fins (increased outer surface area)

  • Good mechanical strength & fatigue resistance

  • Long service life in marine and industrial cooling applications

  • Smooth inner bore ensures minimal pressure drop for fluids
