As a heat exchange element, finned tubes work in high temperature flue gas conditions for a long time. For example, finned tubes for boiler heat exchangers are used in harsh environments, high temperature and high pressure and in a corrosive atmosphere. This requires finned tubes to have high performance. index.
1), anti-corrosion performance
2), wear resistance
3), low contact thermal resistance
4), high stability
5), anti-fouling ability
The main characteristics of high-frequency welded finned tubes: first of all, due to the fast welding speed, the product has a strong self cooling effect, which not only has a small heat effect, but also is not easy to oxidize, so the microstructure and performance of the weld are very excellent. Secondly, it has excellent corrosion resistance, wear resistance and high stability. In addition, the heat exchange area of high-frequency welded finned tubes is large.
Finned tubes are widely used in petrochemical, machinery, metallurgy, rubber, printing and dyeing, medicine, food, electric power, automobile, drying and other industries. Important heat transfer element in mold, heat sink and heat pipe technology. In particular, steel sheet radiators are widely used in industrial and commercial buildings such as offices, residences, hotels, workshops, and greenhouses. Plays an excellent role in heating.
