High Frequency Welded Finned Tubes ASTM A210 A1 For Air Heat Transfer Equipment
Helical solid fin tubes, also known as HFW finned tubes, are manufactured using a high frequency welding process. HFW finned tubes are widely used in heat exchangers, boilers, air coolers, economizers and other thermal applications.
ASTM A210 This specification covers minimum-wall-thickness, seamless medium-carbon steel, boiler tubes and boiler flues, including safe ends, arch and stay tubes, and superheater tubes.
| Grade | C | Mn | P | S | Si |
|---|---|---|---|---|---|
| A1 | 0.27 | 0.93max | 0.035 | 0.035 | 0.10 |
For each reduction of 0.01% below the specified carbon maximum, an increase of 0.06% manganese above the specified maximum will be permitted up to a maximum of 1.35%.
| Grade | Tensile Strength, min | Yield Strength (0.2% Offset, min) |
|---|---|---|
| A1 | 60ksi (415 MPa) | 37ksi (255 MPa) |
| Elongation min. | 30% | Hardness, max |
| 143 HB | Rockwell: 79 HRB |
Steel 1018/A36 are all materials of low carbon steel/mild steel commonly used in manufacturing and construction.
Properties: good ductility and machinability; moderate strength; can be case-hardened (carburized) for improved surface hardness.
Generally applicable to power stations or large high-temperature equipment in the oil industry:
| Type | Description | Base tube O.D. (mm) | Fin pitch | Fin height | Fin thick |
|---|---|---|---|---|---|
| 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 |
| Low fin tube / T-type fin tube | 10-38 | 0.6~2 | <1.6 | ~0.3 | |
| Bamboo tube / corrugated tube | 16-51 | 8.0~30 | <2.5 | ~0.3 | |
| Wound | L / KL / LL type fin tube | 16-63 | 2.1~5 | <17 | ~0.4 |
| String | String fin tube | 25-38 | 2.1-3.5 | <20 | 0.2-0.5 |
| U-type | U-type fin tube | 16-38 | / | / | / |
| Welding | HF-welding fin tube | 16-219 | 3~25 | 5~30 | 0.8-3 |
| H/HH type fin tube | 25-63 | 8~30 | <200 | 1.5-3.5 | |
| Studed fin tube | 25-219 | 8~30 | 5~35 | φ5-20 |
