HFW Finned Tubes: TP347H Base with Carbon Steel Fins
Engineered for extreme thermal efficiency in corrosive environments, YUHONG HFW finned tubes combine TP347H austenitic stainless steel base tubes with carbon steel (CS) fins via precision high-frequency resistance welding. This hybrid construction delivers superior oxidation resistance at elevated temperatures (TP347H) and cost-effective heat transfer enhancement (CS fins), ideal for high-pressure boilers, HRSGs, and sulfur recovery units.
| Component | Material Grade | Key Properties |
|---|---|---|
| Base Tube | ASTM A376 TP347H | 18% Cr-10% Ni-Nb stabilized, exceptional creep strength (≤815°C), resists intergranular corrosion & oxidation |
| Fins | Carbon Steel | High thermal conductivity (50 W/m·K), economical scaling solution for non-corrosive zones |
| Parameter | Specification |
|---|---|
| OD Range | 16-219 mm |
| Wall Thickness | 2.0 - 6.55 mm |
| Max Temp | 815°C (Continuous) |
| Corrosion Resistance | Excellent in H₂S, SO₃, NaOH environments |
| Feature | Range | Tolerance |
|---|---|---|
| Fin Height | 5-30 mm | ±0.5 mm |
| Fins per inch | 4-35 | ±0.2 |
| Fin Strip Thickness | 0.8-3 mm | ±0.1 mm |
| Max Length | 20-30 meters | Straightness ≤1/1000 |
Key Advantages of HFW Finned Tubes
✓ 30% Longer Service Life vs. 304H/CS composites in cyclic thermal service
✓ Zero Bond Degradation at thermal differentials ≤260°C (fin-to-tube)
✓ Custom Metallurgical Solutions: Post-weld solution annealing available
