imits.Extruded Finned Tube?? The strip material is subjected to controlled deformation under tension giving the optimum contact pressure of the foot of the fin onto the base tube thus maximising the heat transfer properties. The foot of the fin considerably enhances the corrosion protection of the base tube. ?Maximum Working Temperature: 150℃?Atmospheric Corrosion Resistance: Acceptable?Mechnical Resistance: Poor?Fin Materials: Aluminum, Copper?Tube Materials: No theoretical limits.Produ
