Product Description

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
