ASTM A333 Gr.1 low finned tubes are widely used in air-cooled heat exchangers (ACHEs) and process coolers due to their enhanced heat transfer efficiency. These tubes maintain the corrosion resistance and low-temperature toughness of carbon steel, due to featuring an integral external finned surface, increasing the heat exchange area. YUHONG GROUP is expert in fin tubes and has extensive experience in the production and sales of fin tubes.
