Embedded Finned Tubes
Table of Content
Embedded finned tubes from Solitaire Overseas 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, 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.

FAQ
An embedded fin is produced by inserting a fin strip into a groove on the base tube. The groove is then backfilled to secure the fin, ensuring a strong bond.
Finned tubes are commonly used in both household and industrial heat exchangers. They are found in air conditioners, car radiators, and other systems where heat transfer is required. The fins increase the surface area for better heat exchange, improving cooling or heating efficiency.
A fin in a heat exchanger is a corrugated sheet that enhances heat transfer by increasing surface area. It also helps hold the flat plates together, forming a secondary surface for heat exchange.
