ASTM A106 Gr.B Carbon Steel HFW Fin Tubes High Frequency Welded Finned Tube
Overview
High frequency welded finned tube is a type of finned tube, which is mainly welded by high frequency welding and is a new type of excellent heat dissipation element. High frequency welding spiral finned tube is in the steel strip winding steel pipe at the same time, the use of high-frequency current skin effect and proximity effect, the steel strip and the outer surface of the steel pipe heating, until the plastic state or melting, in the winding steel strip under a certain pressure to complete the welding. the welding seam is small, and the surface of the radiator is more solid as well as beautiful. Welding high-frequency welded finned tube on the base tube of the radiator improves the heat transfer coefficient of the heat exchanger side of the radiator and enhances the heat dissipation effect of the radiator, and the excellent heat dissipation effect makes the finned tube more and more popular.
The high-frequency welding process is an improved and upgraded process on the basic welding process, which is also a more excellent welding process.Compared with inlay, brazing (or overall hot-dip galvanizing), it is more advanced in terms of product quality (high welding rate of fins, up to 95%), productivity and automation.
High frequency welded spiral finned 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. High frequency welded finned tubes are highly adaptable and widely used, and have been widely used in a variety of fields such as industry and agriculture. High-frequency welded finned tubes are easy to operate, and users can operate them flexibly and simply to achieve the basic purpose of raising indoor temperature and providing comfort to people in the room.
