High Frequency Welded Finned Tubes – TP304H Base Tube + SS304 Fins
High Frequency Welded Finned Tubes with A312 TP304H base tube and SS304 fins are premium stainless steel finned tubes designed for high-temperature and corrosive environments. The combination of TP304H base tube (high-temperature austenitic stainless steel) and SS304 fins provides excellent heat transfer efficiency, superior oxidation resistance, and long service life in demanding industrial applications.
These tubes are manufactured using the high-frequency resistance welding process, ensuring a strong metallurgical bond between the fins and the base tube without the use of filler material.
The finned tube consists of three main components:
Base Tube – ASTM A312 TP304H
| Element | Content (%) |
|---|---|
| Carbon (C) | 0.04 – 0.10 |
| Manganese (Mn) | ≤ 2.00 |
| Phosphorus (P) | ≤ 0.045 |
| Sulfur (S) | ≤ 0.030 |
| Silicon (Si) | ≤ 1.00 |
| Chromium (Cr) | 18.00 – 20.00 |
| Nickel (Ni) | 8.00 – 11.00 |
Fins – SS304 Stainless Steel
| Element | Content (%) |
|---|---|
| Carbon (C) | ≤ 0.08 |
| Manganese (Mn) | ≤ 2.00 |
| Phosphorus (P) | ≤ 0.045 |
| Sulfur (S) | ≤ 0.030 |
| Silicon (Si) | ≤ 1.00 |
| Chromium (Cr) | 18.00 – 20.00 |
| Nickel (Ni) | 8.00 – 10.50 |
| Parameter | Tolerance | Standard Reference |
|---|---|---|
| Base Tube Outside Diameter | ±0.5% or ±0.3 mm (whichever larger) | ASTM A312 |
| Base Tube Wall Thickness | ±12.5% | ASTM A312 |
| Fin Height | ±0.5 mm | Manufacturer Standard |
| Fin Thickness | ±0.05 mm | Manufacturer Standard |
| Fin Pitch (Fins per meter) | ±5% | Manufacturer Standard |
| Tube Length | +5 mm / -0 mm | Customer Requirement |
