Advantages of HFW Finned Tubes
- Minimal heat affected zone with excellent weld microstructure
- Large heat exchange area reduces heat transfer resistance
- Corrosion and wear resistant with low contact thermal resistance
- Compact design reduces required installation space
- Lower tube side pressure drop reduces operating costs
- Enhanced stiffness and seismic performance
