HD Boiler - ASTM Spiral Boiler Fin Tube Heat Exchanger Steel For Air Preheater
The HF Finned Tube, also known as a high-frequency welded spiral finned tube, is an advanced and high-efficiency heat transfer element designed to maximize thermal performance. This product features extended surfaces (fins) that can be either solid or serrated, providing a heat transfer area up to tens of times greater than that of a bare tube. The finned tubes are created through a process of high-frequency resistance welding (HFERW), introducing a high-frequency current into the workpiece to melt or semi-melt the welding contact surface by resistance heat, followed by applying appropriate pressure to complete the welding. The result is a uniform, clean, and continuous finned tube without additional welding material, ensuring excellent heat flow efficiency and corrosion resistance. The core tube materials include carbon steel, various grades of stainless steel, and alloy steel, making it suitable for a wide range of applications such as power plant boilers, industrial heating systems, and more.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.
