Stud Finned Tube For Heat Exchangers Stud Finned Tube, also known as nail head Finned Tube (also known as needle-shaped tube, nail-shaped ribbed tube), adopts a square or hexagonal arrangement and is equally divided into cylindrical needles welded on the surface of the heat exchange tube. The square or hexagonal reinforced heat exchange nail head tube is assembled and welded to form a high-efficiency and energy-saving needle tube heat exchange tube group. Because the Stud Finned Tube pin rib is a cantilever structure with a compact structure, under the impact of the airflow, the pin rib vibrates, making it difficult for soot to accumulate; coupled with the strong turbulent scouring of the flue gas, the Stud Finned Tube heat exchange The element has high heat transfer efficiency and strong self-cleaning ability.
