welded fin tube

ERW HF spiral fin tube The fin strip is welded continuously and spirally wound onto a polished bare tube. And the tube and fins are bonded together by using high frequency resistance welding technique. The High Frequency Resistance Welded Helical Fin Tubes are widely applied in fired heaters, heat exchanger, boilers, economizers, pre-heaters, coolers, heat pipes, heaters etc…

Laser welded fin tube 100% welding between fin and base tube without using any filler material, The laser welding process is carried out under the protective atmosphere, and no impurity of the weld seam. The Laser Welded Fin Tubes are widely applied in fired heaters, heat exchanger, boilers, economizers, pre-heaters, coolers, heat pipes, heaters etc…
