ASME SA106 Gr. B Carbon Steel Solid Fin Tube For Heaters
High frequency welding fin tubes are specialized components manufactured using high-frequency electrical currents to fuse metal edges without filler materials. These ASME SA106 Gr. B carbon steel finned tubes offer excellent performance in heat transfer applications.
ASME SA106 specification covers seamless carbon steel pipe for high-temperature service in sizes from NPS 1/8 to NPS 48 (DN 6 to DN 1200).
| Grade | C | Mn | P | S | Si | Cr | Cu | Mo | Ni | V |
|---|---|---|---|---|---|---|---|---|---|---|
| Gr. B | 0.30 | 0.29-1.06 | 0.035 | 0.035 | 0.10 | 0.40 | 0.40 | 0.15 | 0.40 | 0.08 |
| Grade | Tensile Strength (min) | Yield Strength (0.2% Offset, min) |
|---|---|---|
| Gr.B | 60ksi (415 MPa) | 35ksi (240 MPa) |
- Minimal heat affected zone with excellent weld microstructure
- Large heat exchange area reduces heat transfer resistance
- Corrosion and wear resistant with low contact thermal resistance
- Compact design reduces required installation space
- Lower tube side pressure drop reduces operating costs
- Enhanced stiffness and seismic performance
| Type | Description | Base tube O.D. (mm) | Fin pitch (mm) | Fin height (mm) | Fin thickness (mm) |
|---|---|---|---|---|---|
| Embedded | G-type fin tube | 16-63 | 2.1~5 | <17 | ~0.4 |
| Extruded | Single metal / Combined metal | 8-51 | 1.6~10 | <17 | 0.2-0.4 |
