Fin Type: H Type Fin Tube. Tube Material: Carbon steel, stainless steel, aluminum. Tube OD: 21.3mm-73mm. Tube Thickness: 2mm-7.62mm. Fin Material: Carbon steel, Stainless steel , Alloy. Fin Tube Length: No Limit. Max Working Temperature: 300 C. Atmospheric Corrorsion Resisitance: OK. Mechanical Resistance: Good. Fin Material: Copper, Aluminum, carbon steel, stainless steel. Base Tube materials: Any material available, such as Carbon steel Tube, ASTM A179, ASTM A192, ASTM A210, stainless tube ASTM A269, ASTM A213 T5, ASTM A213 T11, ASTM A213 T22, 304, 316. The advantage of the square fin tube: Increase tube outside surface and improve heat transfer efficiency. Reduce the number of tubes arranged for the heat exchanger equipments than bare tube. Reduce the flue gas velocity and reduce the wear rate and prolong the life-span for the equipment. H type fins have the best soot blowing effect due to the formation of straight passages on both sides. Can offer larger surface area than spiral finned tubes.
