Finning, Bending, Coiling & Fabricating

Embedded Finned Tubes

Unity Tube offers Embedded Finned Tubing in both similar & dissimilar metals. During the Finning process, metal is manipulated along the outside diameter of the tube to create a helical groove. The fin is then applied into the groove and the metal that was initially displaced is now backfilled around the base of the fin locking it into the helical groove. This type of fin attachment allows the finned tube to withstand higher operating temperatures and thermal cycling more efficiently.
