High Frequency Welded Serrated Finned Tubes – ASTM A312 TP304H Base Tube
High Frequency Welded Serrated Finned Tubes with ASTM A312 TP304H base tubes are premium heat transfer components designed for high-temperature, high-pressure, and corrosive environments. Manufactured through a continuous high-frequency resistance welding process, these tubes combine the excellent corrosion resistance of TP304H stainless steel with serrated fins that dramatically increase external surface area, delivering superior heat exchange efficiency in boilers, heat recovery systems, and process heaters.
The finned tube consists of three integrated elements:
Base Tube – ASTM A312 TP304H
| Element | Content (%) |
|---|---|
| Carbon (C) | 0.04–0.10 |
| Chromium (Cr) | 18.0–20.0 |
| Nickel (Ni) | 8.0–11.0 |
| Manganese (Mn) | ≤2.00 |
| Silicon (Si) | ≤0.75 |
| Phosphorus (P) | ≤0.040 |
| Sulfur (S) | ≤0.030 |
| Iron (Fe) | Balance |
| Parameter | Standard Tolerance | Tight Tolerance (Available) |
|---|---|---|
| Base Tube OD | ±0.5% or ±0.3 mm | ±0.2 mm |
| Base Tube Wall Thickness | ±12.5% | ±10% |
| Fin Height | ±0.8 mm | ±0.5 mm |
| Fin Thickness | ±0.15 mm | ±0.10 mm |
| Fin Pitch | ±0.5 mm / 25 mm | ±0.3 mm / 25 mm |
| Overall Tube Length | ±3 mm / m | ±2 mm / m |
| Serration Depth | ±0.5 mm | ±0.3 mm |
