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…

Low fin tube Low fin tube are mainly used in the condnsers and evaporators for air cooler and refrigerator, absorption refrigerator, oil cooler and other heat exchangers. And other industry such as coal power stations, nuclear power stations，boat heat exchangers, air cooler. Heat recovery system, dryers and heaters in chemical industries.

G Fin Tube (or Embedded Fin) Finis embedded into the outer wall of the tube, but gives no surface protection. Ingeneral use for continuous process applications; ie refineries, petrochemical,fertilizer and gas plants.

Extruded Fins / Extruded serrated Fins Finned tube is composited with iron-aluminum or copper-aluminum tube rolling out the fin, which feathers are tightness, small heat resistance, good heat transfer performance, high strength, small flow losses, strong corrosion resistant performance, not easy to deformation and a long working lifetime in cold and hot condition,etc. The fin givescomplete 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.

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…
