Manufacturing Process
Longitudinal I/L or U-shaped fins are precision-welded onto core plain tubes using advanced resistance welding technology or welding with filler metal (spot welding). This process ensures optimal heat transfer and structural integrity.
Available Configurations
- U-bend tubes with longitudinal fins and fin tube coils
- Fin types: one-piece shape, standard U-bent shape, cut & twist, perforated type
- Fin channels welded to tubes in opposite pairs
- Customizable fin height, number of fins, and fin thickness
- Compatible with both OD tube and NB pipe applications
Industrial Applications
- Chemical, petrochemical, oil, and power industries
- Heat exchangers and fired heaters
- Gas coolers and heaters
- Tank heating systems
Competitive Advantages
- Extended working life compared to ordinary helical fin tubes
- Enhanced safety and energy efficiency
Performance Benefits
- Superior heat transfer rates for viscous liquids
- Perforated fin design prevents liquid drainage issues
- Ideal for horizontal heat exchanger applications
