| High Light | Spiral welded finned tubes for heat exchangers ，A106 carbon steel finned tubes ，CS fin tubes with spiral weld | ||
High-frequency welded (HFW) finned tubes combine ASTM A106 Gr.B seamless carbon steel
base tubes with carbon steel fins using advanced solid-state welding technology. These tubes
deliver 8-10x higher heat transfer efficiency versus bare pipes, ideal for heat recovery systems,
boilers, and process heaters operating at ≤400°C.
