| High Light | ASME SA209 finned tubes ，Embedded G fin tubes for boilers ，Boiler economizer finned tubes | ||
ASME SA209 Embedded Finned Tubes are engineered for boiler economizers where efficient heat recovery and long-term operational reliability are required. These finned tubes combine ASME SA209 alloy steel base tubes with high-purity AL1060 aluminum fins, which are mechanically embedded into precision-machined helical grooves on the tube surface. The embedding process creates a secure mechanical bond that maintains excellent heat transfer performance while reducing fin loosening during thermal cycling.
Compared with plain tubes, embedded finned tubes provide a significantly larger external heat transfer area, allowing economizers to recover more waste heat from flue gases, improve boiler efficiency, and reduce overall fuel consumption. The aluminum fin material offers excellent thermal conductivity and low weight, making it suitable for medium-temperature gas-side heat exchange applications.
Manufactured under strict quality control procedures, these finned tubes are suitable for new boiler installations, retrofit projects, and various industrial heat recovery systems.
Embedded finned tubes are widely used in:
| Item | Standard Range |
|---|---|
| Base Tube Material | ASME SA209 |
| Fin Material | AL1060 Aluminum |
| Tube Outside Diameter | 25.4–63.5 mm |
| Tube Wall Thickness | 2.5–8.0 mm |
| Tube Length | Up to 18,000 mm |
| Fin Height | 8–16 mm |
| Fin Thickness | 0.35–0.60 mm |
| Fin Pitch | 2.5–6.0 mm |
| Overall Finned Tube Diameter | 45–95 mm |
| Manufacturing Method | Embedded Helical Fin |
The external surface of the ASME SA209 tube is machined with continuous helical grooves. AL1060 aluminum strip is then inserted into the grooves under controlled pressure. The groove edges are mechanically closed over the fin base, creating a firm mechanical bond between the tube and fin without welding. This manufacturing process improves fin retention and ensures consistent thermal performance throughout the service life.
Each embedded finned tube undergoes comprehensive inspection before shipment, including:
Inspection can be performed according to customer specifications or third-party requirements.
