DURA-G Embedded Finned Tube
DuraFin Tube embedded finned tubing offers exceptional thermal efficiency at higher temperature ranges with solid fin-to-tube contact. Fins are mechanically locked into a helical groove in the outside of the tube. Rollers press displaced metal from the groove against the base of the fin to form a lasting metal-to-metal bond.
The Embedded Finned Tube can also be offered in following variations to the Fin:
Perforated Fin (DURA-GP)
