HF Finned Tube For Heat Exchangers
HF Finned Tube is also known as high frequency welded spiral finned tube, high frequency welded spiral finned tube is a tubular high-efficiency heat transfer element with spiral fins. The extended surfaces (fins) can be solid or serrated and have up to tens of times more heat transfer area than a bare tube.

HF Finned Tube is a spiral winding of steel fins, which is continuously welded on the steel pipe by high frequency resistance welding (HFERW). A high-frequency current is introduced into the workpiece, the welding contact surface is melted or semi-melted by resistance heat, and then appropriate pressure is applied to the welding contact surface to complete the welding of the finned tube. This produces a uniform, clean and continuous finned tube combined with no additional welding material for very efficient heat flow and corrosion resistance.

High-frequency welded spiral finned tube is one of the most widely used spiral finned tubes.
