fin tube

Extruded type: with cold rolled extruded fin Thirteen extrusion fining lines, daily capacity around 9000 meters The extruded fin gives complete protection to the base tube and is much stronger than the applied type due to work hardening of the fin material during the extrusion process.

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…
