ASTM A312 TP304H Serrated Fin Tubes, High Frequency Welding For Coil Cooler

What are Serrated Fin Tubes?
  • A serrated finned tube is an efficient heat transfer element widely used in various industrial heat exchange equipment.
  • Its unique serrated design enhances the heat transfer efficiency and anti-fouling performance, making it highly popular.
Structure of Serrated Finned Tubes
  • Structural characteristic is the dense arrangement of fins, with fin spacing as small as 0.5mm
  • Fins are distributed in a serrated pattern
  • This design creates intense turbulence in the fluid flow outside the tube, effectively increasing heat transfer efficiency
Manufacturing Process
  • Similar to high-frequency welded spiral finned tubes
  • Requires local cutting of the strip material before winding
  • During winding, cut parts naturally separate to form a gear shape
  • Design simplifies winding process, reduces deformation
  • Ensures tight bonding, high strength, good resistance to thermal and mechanical vibrations
  • Excellent thermal expansion performance, low flow loss, strong corrosion resistance
Advantages
  • High Heat Transfer Efficiency: Serrated fins create turbulence in flue gas, resulting in higher film heat transfer coefficient (30-50 kcal/m²)
  • Strong Anti-Fouling Performance: Serrated design disrupts fluid boundary layer, reducing ash accumulation
  • Good Mechanical Performance: High-frequency welding ensures strong bond between fins and base tube
Applications
  • Industrial Waste Heat Recovery
  • Air Conditioning and Refrigeration
  • Energy Utilization
