Technical Comparison of Different Finned Tube Types
Extruded Type
Extruded finned tubes are formed by fitting an aluminium tube over a stainless steel base tube and then extruding it with specialized equipment to create fins. This process ensures tight contact between fins and base tube, providing excellent thermal conductivity.
- Base tube material: Carbon steel, Various alloy steels, Stainless steel, Copper tube
- Minimum base tube diameter: Φ16 mm
- Fins OD: Φ16-Φ70 mm
- Fin material: Aluminium
- Fin pitch: 0-8mm, generally 2.3-5.0mm
- Fin thickness: 0.35-0.5 mm
- Length: 0-12m (longer than 12m acceptable)
High Frequency Welding Type
High-frequency welded finned tubes use high-frequency current to generate heat that welds fins to the base tube, creating a strong bond.
- Base tube material: Carbon steel (20#, 10#, Q235), Various alloy steels, Stainless steel (304, 316L)
- Base tube OD: Φ20-Φ165 mm
- Thickness: 2-8mm
- Fin material: Q195L, SPCC(08F), SPHE(08AL), Stainless steel 304, 316L
- Fin height: 5-30mm, must be smaller than base tube radius
- Fin thread pitch: 5-30mm, better more than 5 fins
- Fin thickness: 0.7-3.0mm
L/LL/KL/KLM/G (Embedded) Type
Embedded finned tubes mechanically embed fins into the base tube surface, creating a strong connection particularly suitable for high-temperature, high-pressure environments.
- Base tube material: Carbon steel, Various alloy steels, Stainless steel, Copper tube
- Base tube diameter: Minimum 20mm
- Fin height: 8-15mm
- Fin material: 1060 Aluminium
- Fin pitch: 2.3-5.0mm
- Fin thickness: 0.4-0.5mm
- Length: 0-12m (longer than 12m acceptable)

|---|---|---|---|---|
| Extruded Aluminium Fin | 180-220 | 85-92 | 280 | Excellent |
| High Frequency Welded Stainless Steel Fin | 15-25 | 75-85 | 650 | Outstanding |
| Embedded Aluminium Fin | 170-210 | 80-90 | 350 | Good |
Aluminium Fin Stainless Steel Finned Tube Manufacturing Process
The manufacturing of aluminium fin stainless steel finned tubes is a precision engineering process:
- Precision cleaning and preparation of stainless steel base tubes
- Sleeving aluminium tubes over stainless steel base tubes
- Feeding the assembly into a triple-spindle finning machine
- Using three special multi-disc packs to extrude the aluminium tube into helical high fins
- Simultaneously reducing the inner diameter to create firm pressure contact with the core tube
- Conducting quality inspection and performance testing
This process ensures tight contact between fins and base tube, maximizing heat transfer efficiency.
