ASTM A179 + Al Aleta Embedded Finned Tube G-Type Para Calderas
YUHONG Group offers ASTM A179 Embedded G-Type Aluminum Finned Tube / Tubo Aletado and we sell this fin tubes in over 70countries.
We can handle kinds of projects in various industries, such as heat exchanger / boiler projects, marine projects, oil & gas projects etc in petroleum industry,power industry,chemical industry and heat service systems,etc.
Fin 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.
Embedded G type Finned Tube provides a perfect connection between the fin and the tubes . The 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.Embedded Fin tubes can be used in higher temperatures and are very durable and they 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 .
