Our extruded finned tubes utilize advanced roll forming technology that creates seamless integration between fins and tubes. This eliminates thermal resistance at the interface, significantly enhancing heat exchange efficiency. The monolithic construction provides superior structural integrity, vibration resistance, corrosion protection, and extended service life compared to HF welded or wrapped alternatives.
Available in single metal (copper, aluminum, copper-nickel) and bimetal configurations with core tubes of harder materials for demanding applications.
Customizable Dimensions: Outside diameter and inside diameter tailored to requirements
Fin Height: 0-12mm range
Fins per Inch: 5-26 fins density options
Fin Thickness: 0.3-0.5mm thickness specifications
Wall Thickness: 0.7-2.0mm tube wall options
Ideal for liquid cooling and heating systems including water heater coils, industrial oil coolers, boiler heat transfer components, heat recovery systems, and condenser/evaporator units in HVAC and refrigeration applications.
