Carbon Steel ASTM A106 Gr. B High Frequency Welded Finned Tube， Spiral U Bend Fin Tube
High Frequency Welded Spiral U Bend Fin Tube is a type of fin tubes， which is mainly welded by high frequency welding and is a new type of excellent heat dissipation elements. The high frequency welding finned tube is welded with high frequency current， the welding method is reliable and excellent， the welding seam is small， and the surface of the radiator is more solid as well as beautiful. ASTM A106 Gr.B HFW spiral fin tube is one of the most widely used spiral finned tubes， and is now widely used in power， metallurgy， waste heat recovery in cement industry and petrochemical industry.

| Tensile Strength | 60000 (415) MPa |
| Yield Strength (0.2%Offset) | 35000 (240) MPa |
Characteristics:
1.The fast welding speed and the strong self-cooling effect of the welded parts， and the heat-affected zone is small and the oxidation is not easy to occur， so the organization and performance of the weld is excellent.
2.Low contact heat resistance， high stability， anti-dust accumulation ability
3.Large heat exchanger area
Manufacturing Process:
The fin strip is welded continuously and spirally wound onto a polished bare tube. The tube and fins are bonded together by using high frequency resistance welding technique.
Applications:
Condenser
Evaporator
Radiator
Refrigeration
Heat Exchanger&Superheater
