G-Fins Tubes for Heat Exchanger
Embedded finned tubes from Datang provide excellent thermal efficiency, especially in high-temperature applications. The fins are securely fixed into a helical groove on the outer surface of the tube. This is achieved by mechanically locking the fins in place, followed by rollers that press the displaced metal from the groove tightly against the base of the fins.
This process creates a durable metal-to-metal bond, ensuring long-lasting performance and efficient heat transfer.
‘G’ Fin Tubes / Embedded Fin Tubes
‘G’ Fin Tubes, also referred to as Embedded Fin Tubes, are ideal for high-temperature environments with lower corrosive conditions. These fin tubes are created by embedding a fin strip into a groove cut into the base tube. Once the fin is placed in the groove, the groove is backfilled to firmly secure the fin to the base tube.
The grooving, fin insertion, and backfilling are done as a continuous process, ensuring a strong bond between the fin and the tube. This secure connection allows for excellent heat transfer efficiency, making ‘G’ Fin Tubes highly effective in demanding applications.
