Ürün Tanımı

ASTM B111 C68700 Copper Alloy Low Fin Tube for Seawater Cooling Heat Exchangers

 

ASTM B111 C68700 seamless low-finned tubes are designed to increase heat exchange area. Their key advantages include excellent resistance to erosion/impact corrosion in high-velocity seawater and brackish water. The copper alloy material offers good thermal conductivity and natural resistance to biofouling. Due to its excellent expansion, bending, and weldability, it is also suitable for heat exchanger tube bundles. The low-fin design perfectly matches liquid-side cooling (seawater, brine) inside the tube and steam/gas cooling on the finned side outside the tube.

Application ( Not limited to the following )

 

1.Power Generation Industry (Core Application)

 

Thermal Power Plants/Coastal Thermal Power Plants:

*Surface Condenser Low-Finned Tube Bundles.
*For circulating water heat exchangers in coastal brine-cooled hydroelectric power plants.
*Suitable for high-flow cooling water, effectively preventing impact corrosion of ordinary brass tubes.

 

Nuclear Power Plants (Coastal Units):

*Secondary Circuit Seawater-Cooled Condenser, etc.

 

2.Offshore and nearshore oil and gas

 

Shipbuilding industry:

*Main engine seawater condensers, auxiliary steam condensers.Freshwater generator distillation tubes, air conditioning evaporators.

Offshore platforms/FPSO/FPU:

*Seawater cooling heat exchangers, crude oil coolers, ethylene glycol coolers, gas scrubber condensers.

Low-finned tubes reduce shell size while resisting erosion from high-velocity, sand-laden seawater.

 

3. Seawater Desalination Plants

 

*Distillation Evaporator and Condenser Heat Exchange Sections

*Post-treatment Brine Cooling Heat Exchangers

Main Advantages: Resistant to high-concentration brine corrosion and high lateral flow velocity erosion; longer service life than ordinary copper tubes

 

4. Petrochemical and Refining Industries

 

*Low-finned Condensers for Sulfur Recovery Units 

 

5. HVAC, District Cooling, and Industrial Refrigeration

 

*Evaporators/Condensers for Large Industrial Chiller Units (Using seawater or brackish water)
