High-Frequency Welded Serrated Finned Tubes Base Tube: ASTM A335 P11 | Fins: Aluminum Alloy GR.11
High-frequency welded serrated finned tubes combine ASTM A335 P11 chromium-molybdenum alloy steel base tubes with aluminum alloy GR.11 fins via advanced HFW technology. Designed for extreme conditions (≤600°C), they deliver 30%+ higher thermal efficiency than smooth tubes.
| Component | Base Tube (A335 P11) | Fins (GR.11) |
|---|---|---|
| Carbon (C) | 0.05-0.15% | ≤0.15% |
| Silicon (Si) | 0.50-1.00% | 0.50-1.50% |
| Manganese (Mn) | 0.30-0.60% | ≤0.05% |
| Chromium (Cr) | 1.00-1.50% | - |
| Molybdenum (Mo) | 0.44-0.65% | - |
| Aluminum (Al) | - | ≥98.5% |
| Iron (Fe) | Balance | ≤0.7% |
Key Material Advantages:
HFW Technology: Fin-to-base bond strength >100MPa (per ASTM E8)
Helical Pitch: 3-10 fins/inch (customizable)
100% Weld Penetration: Ensures zero thermal contact resistance
