High Frequency Welded Fin Tube Product Description:
Welded Helical solid Fin Tube are used in petrochemical field and industrial boilers to heat (heaters) or cool (coolers) or to recuperate heat from industrial fumes. Our finned pipe has a fin strip wrapped and continuously welded onto the outside surface of the tube by means of MIG welding technique. This process gives a very high heating transfer coefficient, about 4-5 times higher than other conventional types of finning, because of the continuity between tube and fin strip materials. If you add the possibility to weld each other very different materials, you can consider an optimum product adaptable to numerous uses and different environments. We are always available to try new technical solutions on Clients requests.
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. The simple and economic installation
The maximum length of high frequency welding spiral finned tube can reach 6 meters, that reduces the join points, making the installation more economic, efficient, and also reduces the leakage probability of joints.
2. Easy maintenance
After installation, high frequency welding spiral fin tube needs no longer to be maintained.
3. High efficiency
The heat dissipation area of high frequency welding spiral fin tube is more than 8 times of the light tube.The internal is smooth, so the internal flow resistance is small.
4. Long service life
Fin and pipes with high mechanical strength, so the tensile strength is more than 200 mpa. Both inside and outside of the tube are all made of hot dip galvanized processing.
High Frequency Welded Fin Tube(Welded Aluminum Pipe) Properties:
Manufacturing Process:- Continuously Welded Spiral Fin Tube
Fin To Tube Bond:- Excellent
Heat Transfer Efficiency:- Excellent
Mechanical Resistance:- Excellent (Hence can be frequently cleaned with high pressure jets unlike other fin tubes. Thereby reducing down time and increasing overall life)
Corrosion Protection:- Moderate
Temperature Range:- Up to Maximum 500 Deg C
High Frequency Welded Fin Tube(Spiral Welded Pipe) Applications：
High frequency welded spiral finned tubes are generally used for petrochemical industry and mostly installed on the convection sections of fired heaters, waste heat boilers, economizers, air preheaters, and heat exchangers involving the transfer of heat from a hot fluid to a colder fluid through a tube wall.
