Continuous Spiral Crimped Fin TubesThese types of fins are semi-crimped and wrapped under tension around the outside of the base tube. Fins are either tack welded or brazed to the base tube at each end of the tube. These finned tubes can be further Hot Dipped Galvanised for surface protection where as the deposition of Zinc also adds up to the efficiency of finned tubes.Maximum Operating Temperature-250°CBase Tube Diameter : 5/8 to 3 (15.8 mm to 76.2 mm)Tube Material : Carbon Steel, Stainless Steel, Copper, Cupro-NickelFin Material : Carbon Steel, Stainless Steel, Copper, Aluminium, BrassFin Height : ¼ to ¾ 6.4 mm to 20 mm.Fin Pitch : 3fins/inch to 11 fins/ inch 118 fins/meter to 433 fins/meter.ApplicationCommercial application for air heating or air cooling up to 130°C to 150°C using steam / Thermic fluid / Hot water as heating media or water as cooling media.
