ASTM A179 Carbon Steel Embedded Finned Tube G-Type, Tubos Aletados
YUHONG Group can handle kinds of projects, such as heat exchanger / boiler projects, marine projects, oil & gas projects etc. We offer various types of fin tubes.
Fin tubes are used in many different industries. These tubes have a finned surface, which increases their surface area and allows them to transfer heat more efficiently. Because of that,this makes them ideal for applications where high heat transfer rates are required.

ASTM A179 Embedded G-Type Aluminum Fin Tube we sell in over 70 countries.Embedded Fin Tubes also called G type Finned Tube, Embedded Finned Tube provides a perfect connection between the fin and the tubes . The Embedded Fin tubes main design is that through professional equipment groove the tubes and fin insert fins into the helical groove. Finally combined the fin and tubes as intergral.(G-Fins) are made by winding aluminium or copper strip into a helical groove machined on the outer surface of the tube.
Embedded Fin tubes can be used in higher temperatures and are very durable. Embedded Fin tubes 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 .
