High Frequency Welded Fin Tube Product Description:
The major uses for high frequency welded Fin Tube are in the heat recovery associated with boilers for power generation and in furnace applications for the petrochemical industry.
The steel fin, that may be solid or serrated, is helically wound and continuously welded to the tube by high frequency electric resistance welding. This produces a homogeneous, clean and continuous fin-to-tube bond with no additional weld material, for a very efficient heat flow and resistance to corrosion.
The use of high-frequency current results in much localized heating of the tube surface and the edge of the fin. This skin effect produces higher weld speeds, while post-weld heat treatment is not considered necessary because of the superficial nature of the changes in the micro structure.
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 homogeneous, clean and continuous fin-to-tube bond with no additional weld material, for a very efficient heat flow and resistance to corrosion.
High Frequency Welded Fin Tube(Electric Resistance Welded Pipe) Advantages:
1.Simple and economical installation High frequency welding spiral fin tube are with zero connection point, so that the installation is more economical, fast, and reduce the probability of leakage at the joint.
2. Easy maintenance. After installation, high-frequency welded spiral fin tube doesn’t need additional maintenance.
3. High efficiency High frequency welding spiral fin tube is full contact welding between fin and steel tube whose heat dissipation area is more than 8 times of bare tube. In addition, the smooth internal wall reduces water flow resistance as well.
4. Long service life, Fin and pipes are combined with high mechanical strength whose tensile strength is more than 200 Mpa. Both inside and outside of the tube are treated with hot dip galvanized processing.
