ASTM A179 Extruded Finned Tubes are high-performance heat transfer components manufactured from ASTM A179 seamless low-carbon steel tubes with an extruded aluminum fin sleeve mechanically bonded to the base tube. The extrusion process forms a solid, continuous fin structure that provides excellent thermal conductivity, superior mechanical strength, and long-term corrosion resistance.
Compared with conventional wound finned tubes, extruded fin tubes offer enhanced fin-to-tube contact, improved heat transfer efficiency, and exceptional durability in demanding industrial environments. These finned tubes are widely used in air-cooled heat exchangers, fin fan coolers, economizers, waste heat recovery units, power generation facilities, petrochemical plants, HVAC systems, and process cooling equipment.
The extruded finned tube is produced by first fitting an aluminum sleeve over the ASTM A179 base tube. Special extrusion rollers then plastically deform the outer aluminum layer, creating fins while simultaneously forming an intimate mechanical bond with the steel tube underneath.
This process creates:
The resulting fin structure becomes an integral part of the tube assembly, providing superior reliability under long-term operating conditions.
The following dimensions represent common manufacturing capabilities. Customized sizes are available upon request.
| Parameter | Standard Range |
|---|---|
| Base Tube OD | 15.88 mm – 50.8 mm |
| Base Tube Wall Thickness | 1.2 mm – 5.0 mm |
| Tube Length | Up to 18,000 mm |
| Fin Outside Diameter | 30 mm – 80 mm |
| Fin Height | 7 mm – 16 mm |
| Fin Thickness | 0.3 mm – 0.5 mm |
| Fin Density | 8 – 16 FPI |
| Fin Pitch | 1.6 mm – 3.2 mm |
| Fin Material | Aluminum 1060 / 1070 / 1100 |
The ASTM A179 specification covers seamless cold-drawn low-carbon steel tubes intended for heat exchanger and condenser applications.
| Element | Composition (%) |
|---|---|
| Carbon (C) | ≤ 0.18 |
| Manganese (Mn) | 0.27 – 0.63 |
| Phosphorus (P) | ≤ 0.035 |
| Sulfur (S) | ≤ 0.035 |
The low carbon content provides excellent weldability, ductility, and thermal conductivity.
| Property | Value |
|---|---|
| Tensile Strength | ≥ 325 MPa |
| Yield Strength | ≥ 180 MPa |
| Elongation | ≥ 35% |
| Hardness | Typically ≤ 72 HRB |
These properties ensure excellent forming characteristics and reliable performance under thermal cycling conditions.
The extruded fin design significantly increases the external heat transfer area compared with bare tubes.
Benefits Include:
The fully bonded fin structure minimizes contact resistance, allowing heat to transfer efficiently from the tube wall to the surrounding air.
Every ASTM A179 extruded finned tube can undergo comprehensive inspection procedures to ensure compliance with project specifications and international standards.
Inspection reports can be supplied according to customer requirements.
Used extensively in refineries, petrochemical facilities, and gas processing plants where air serves as the cooling medium.
Applied in condensers, auxiliary cooling systems, and waste heat recovery units.
Suitable for process cooling, hydrocarbon condensation, and thermal recovery systems.
Widely used in chillers, condensers, evaporators, and industrial ventilation systems.
Enhances energy efficiency by recovering heat from exhaust gases and process streams.
