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