Stainless Steel Tube With Aluminium Fins For Cooler  

High Frequency Welded Fin Tube Product Description: we supply high frequency helical high fin tube for the petrochemical and power generation industry. A continuous helical fin is attached to the base of the tube by high frequency electric resistance welding. The helical fins produce a homogeneous, clean, continuous bond for efficient heat flow and resistance to corrosion. The high frequency helical high finned tubes can be used in: Boilers\coolers\economizers\fired heaters\furnaces\heat exchangers\heat pipes   High Frequency Finned Tube Manufacturing Process: The steel fin is helical wound and continuously welded to the tube by high frequency electric resistance welding(HFERW). The high-frequency current is introduced into the work piece, and the welding contact surface is melted or semi-melted by resistance heat, then apply appropriate pressure to the weld contact surface to complete the welding of the finned tube. This produces an homoge…
