Laser welded finned tubes manufacturers
Laser Welded Finned Tubes
Zero Contact Resistance · Ultimate Heat Transfer Efficiency
Laser Welded Finned Tubes Technology Advantages
Metallurgical Bonding
100% fusion between fin and tube eliminates contact thermal resistance, increasing heat transfer efficiency 8x compared to smooth tubes
Superior Durability
Weld penetration >99% with 600MPa strength prevents crevice corrosion and extends service life by 30% in harsh environments
Compact Design
Fin spacing down to 2.5mm (vs 4.5mm+ for HF welding) increases heat transfer area by 50%, reducing heat exchanger volume by 40%
