HFW Finned Tube High Frequency Welded Solid Finned Tube for Heat Exchanger

Description

HFW Solid Finned Tubes short for High Frequency Welded Helical Spiral Solid Finned Tube. Helical finned Tubes are manufactured in both Solid finned Tube and Serrated Finned Tube. Helical Finned Tubes provide the designer with high thermal efficiency and compact design solutions for a whole range of heat exchangers.

High frequency welded spiral finned tube is to use the skin effect and proximity effect of high frequency current to heat the steel strip and the outer surface of the steel tube until the plastic state or melting, while the steel strip is wound around the steel tube. The welding is completed under a certain pressure when the steel strip is wound. This kind of high-frequency welding is a solid phase welding. Compared with inlay, brazing (or overall hot galvanizing) and other methods, it is more advanced in terms of product quality (high welding rate of fins, up to 95%)productivity and automation.

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.
This welded steel finned tube configuration can be used for any practically heat exchanger application, and is particularly suited to high temperature and high pressure applications. The important features of this configuration are efficient, effective bond of fin to tube under all conditions of temperature and pressure, and ability to withstand high fin-side temperatures.
