Description:
Continuous Spiral Crimped 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 - 300°C. Thermotech Industries offers a range of tubes for application in boilers and heat exchangers.
