High Frequency Welded Fin Tube Product Description:
Helical Fin Tube provide the designer with high thermal efficiency and compact design solutions for a whole range of heat exchangers where clean flue gases are used.Helical finned Tubes are manufactured in both Solid and Serrated type.
Helical Solid Finned Tubes are manufacturer by helically wrapping continuous fin strip on tube. HF Resistance Welding Usually Employs Frequency Of 400kHz.The fin wound around the tube And Continuous weld. The fin strip is wounded spirally onto the tube and welded continuously with a high frequency electrical process to the base tube along the spiral root. The fin strip held under tension and confined laterally as it is formed around the tube,thereby ensuring that the strip is in forceful contact with the base tube surface.A continuous weld is applied at the point where the fin strip first begins to bend around the tube diameter, using the gas metal are welding process.
For a given tube or pipe size, the desired heat transfer surface area per unit length of tube can be obtained by specifying the appropriate fin height,fin thickness and /or number of fins per meter of length.
High Frequency Finned Tube Manufacturing Process:
The steel fin (solid or serrated) is helical 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 welding process enables the combination of any grades for studs and tube: carbon, alloy, stainless steels and high nickel alloys. Alloy steel pipes are stress-relieved after studding, according to the relevant specifications for the class and grade of steel used.
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：
Air Cooler,Charge Air Chiller, Condenser,Evaporator, Fluid Cooler, Gas Cooler,Oil Cooler, Radiator, Refrigeration,Steam to Air Heat Exchanger,super heater etc.
