DURA-I Edge Tension Finned Tube

DuraFin Tube offers our standard Edge-Tension fin tubes available in similar or dissimilar metals. Edge tension finned tubing is recommended for moderate duty in normal ambient air applications and on most low-temperature air cooled heat exchangers. During the manufacturing process, fin material is tightly wound around the outside of the tube to secure metal-to-metal contact of the base of the fin with the tube. The Edge Tension Fin can also be supplied with the DURA-IS solder or DURA-IB brazed fin bond.
