Embedded Fin tubes also called G type Finned tube

The Embedded Fin tubes main design involves the fin inserted and welded into a helical groove cut into the tubes. They can be used in higher temperatures, and are very durable. Embedded fins are best suited for the usages that involve high thermal cycling or high temperatures and where the fin side will be subjected to regular cleaning. 

Common Applications: Air Cooled Heat Exchangers, Steam Coils, Air Preheaters.

Max. Working Temperature:  400 °C

Atmospheric Corrosion Resistance: OK

Mechanical Resistance: Poor

Fin Material: Copper, Aluminum

Base Tube materials: Any material available, such as Carbon steel Tube, A179, A192, A210, stainless tube A269/A213 T5 T11 T22 304 316 

Embedded Finned Tube

Embedded Finned tube

This design consists of an aluminum strip placed into a groove on the primary tube, tension wound on edge and finally maintained in place by the groove lip. This fin’s primary applications are high temperature or cyclic services.


Embedded fin tube provides a perfect connection between the fin and the tube.

May be used at temperatures up to 400°C


Embedded finned tubes offer solutions where higher temperatures, continuous thermal cycling and tube vibration due to high velocity air streams can cause failures. The fin is mechanically embedded into a groove that is plowed in the tube O.D. and is locked into place by rolls that force the groove to tightly close around the fin base. Embedded finned tubes are commonly used in applications with metal temperatures up to 750 degrees Fahrenheit.
