ASTM A179 ALuminium Carbon Steel Embeded Fin Tube For Heat Exchanger

Finned tube is a kind of heat exchange element. It is to increase the heat transfer efficiencyļ¼Œ usually by adding fins on the surface of the heat exchanger tube to increase the external surface area (or internal surface area) of the heat exchanger tubeļ¼Œ so as to achieve the purpose of improving the heat transfer efficiency.

 

Embeded Fin Tube
Inlaid spiral finned tubes are pre machined with spiral grooves of a certain width and depth on steel pipesļ¼Œ and then the steel strip is embedded on the steel pipe on a lathe. During the winding processļ¼Œ due to a certain amount of pre tensionļ¼Œ the steel strip will be tightly trapped in the spiral grooveļ¼Œ resulting in a certain contact area between the steel strip and the steel pipe. To prevent the steel strip from rebounding and falling offļ¼Œ both ends of the steel strip should be welded to the steel pipe. For ease of installationļ¼Œ there should be a certain side gap between the steel strip and the spiral groove. If the side gap is too smallļ¼Œ forming interferenceļ¼Œ the inlay process is difficult to proceed smoothly. In additionļ¼Œ the wrapped steel strip always has a certain reboundļ¼Œ which results in poor bonding between the steel strip and the bottom surface of the spiral groove. Inlaying fins can be done on general equipment at a low costļ¼Œ but the process is complex and the production efficiency is low.
