Embedded Finning

TEK-FINS provides high quality Embedded Fin Tubes which are the engineer's choice for applications that require process fluids with operating temperatures to 750°F.  


This fin type is produced by mechanically embedding the fin into a groove that is plowed into the base tube O.D. and is further locked into place by rolls that force the groove to tightly close around the fin base.   This fin type performs extremely well in such high temperatures since the aluminum fin expands at a greater rate than the base tube and the net result is a very tight mechanical bond with extremely positive heat transfer qualities.



3/4" - 1" - 1-1/4" - 1-1/2" diameter tubes

Lengths of up to 60'

Finning with Aluminum 1060-F

8, 9, 10, 11 fins per inch

Fin Height: 0.625 and .50 (hgt in decimal inches)
