Fin-tube manufacturing process

　　Finned tube, also known as a finned pipe. As the name suggests, Coil tube It involves machining numerous fins onto the surface of the original tube—whether on the outer or inner side—to increase the effective heat-transfer area, thereby creating a distinctive heat-exchange element. Finned tubes can be classified into square‑fin tubes, helical‑fin tubes, longitudinal‑fin tubes, helical‑serrated fin tubes, and internally finned tubes; the latter are further divided into single‑metal finned tubes and bimetallic composite finned tubes. Cultivating corporate culture is also an important aspect. Steel‑fin radiators are a type of heat exchanger widely used in gas–liquid heat‑transfer applications. Fins are added to standard base tubes to enhance heat transfer. The base tubes may be made of steel, stainless steel, copper, or other materials, and various specifications of steel strips, stainless‑steel strips, copper strips, round fins, aluminum strips, and more can be employed. Based on fin configuration, finned radiators are categorized as coil‑type, tube‑in‑tube, welded, and plate‑type. Steel–aluminum composite finned tubes are extensively utilized, combining the pressure resistance of steel with the high thermal conductivity of aluminum.

　　Steel finned convection radiators are steel radiators suitable for both steam and hot-water systems. They are primarily used for air heating in forced-air heating, air-conditioning systems, and drying units. Currently, steel… Coil tube Convection radiators are widely used in the heating and ventilation systems of industrial and mining enterprises as well as in buildings. Steel‑wound‑tube convection radiators can operate with steam, hot water, or heat transfer oil as the working medium.

　　Single-metal finned tubes, copper‑wound‑fin tubes, carbon‑steel wound‑fin tubes, stainless‑steel wound‑fin tubes, and cast‑iron (cast‑steel) wound‑fin tubes; classified by application: copper‑wound‑fin tubes, air‑cooled wound‑fin tubes, boiler‑type water‑wall tubes, carbon‑steel wound‑fin tubes, cast‑iron wound‑fin tubes, air‑cooled wound‑fin tubes, industrial waste‑heat recovery wound‑fin tubes, and other specialized wound‑fin tubes. The concept of radiators is quite broad, broadly divided into residential radiators and industrial radiators, with radiators being predominantly used in industrial settings.

　　High-frequency welded spiral-wound thin-plate steel pipe

　　Steel high-frequency welded spiral-wound finned tubes, as critical heat-transfer components in modern cooling systems, are widely employed in finned-tube radiators, significantly enhancing the radiator’s heat dissipation efficiency compared to conventional base tubes. Steel spiral Coil tube High-frequency welding joins the spiral steel tube to the parent pipe, ensuring a strong and stable connection. When wound around the finned‑tube radiator, the high-frequency welded spiral steel tube significantly enhances heat transfer. Because the spiral steel tube is helically wound, it reduces thermal resistance caused by cold air while maintaining stable operation, resulting in superior heat‑transfer performance compared with conventional radiators.

　　High-frequency welded steel spiral tubes boast excellent heat dissipation around their perimeter, and when combined with the enlarged surface area of finned‑tube radiators, the overall thermal performance of such radiators can be 3 to 5 times that of conventional heat‑pipe radiators. Thanks to this superior cooling efficiency, they are increasingly favored by consumers.
