Wound Finned Tubes manufactured with ASME SA179 carbon steel tubes are widely used heat transfer components designed for improving thermal efficiency in heat exchangers, air heaters, economizers, and industrial cooling systems.
The wound fin tube is produced by helically winding a metal strip onto the outside surface of the base tube and mechanically locking the fin foot into a knurled or grooved tube surface. Compared with traditional plain tubes, this structure significantly increases the external heat transfer area while maintaining good mechanical bonding between the tube and fin.
The ASME SA179 base tube provides excellent thermal conductivity, uniform wall thickness, and reliable performance under low to medium temperature heat transfer conditions. These finned tubes are commonly selected for applications requiring efficient heat exchange, compact equipment design, and stable long-term operation.
Wound finned tubes made from ASME SA179 are commonly used in:
They are especially suitable for gas-side heat transfer applications where increasing external surface area is important.
Wound finned tube dimensions include:
Common fin materials include:
Dimensions can be customized according to heat exchanger design requirements, thermal performance calculations, and operating conditions.
ASME SA179 is a specification for seamless cold-drawn low carbon steel tubes used for heat exchangers, condensers, and similar heat transfer equipment.
The material is characterized by:
| Element | Maximum Content |

| Phosphorus (P) | ≤0.035% |
| Sulfur (S) | ≤0.035% |
| Property | Requirement |
| Tensile Strength | ≥325 MPa |
| Yield Strength | ≥180 MPa |
| Elongation | ≥35% |
