Aluminum embedded fin tubes are typically used in higher temperature applications.

1. Air cooler, processing cooling, lube oil cooling

2. Heat exchanger, steam air heater

3. Economizer

4. Gas compressor

5. Waste incinerator

6. Blast furnace/ rotating furnace, etc

Embedded G Fin Tube

the fin strip is wound into a machined groove and securely locked into place by back filling with the base tube.

G fin tube consists of aluminum fin strip that is mechanically embedded into the wall of the tube.
the embedding process is controlled by tooling that first plows a groove into the tubes outside diameter, then guides the base of the fin into the groove and finally locks the fin in place by rolling the groove closed on the base of the fin.
this ensures that maximum heat transfer is maintained at high tube metal temperature 400°C.
