Welded Square Fin Tubes 

Welded Square Fin Tube Welded Square Fin Tube is also called as H/HH Fin Tube.The Welded Square Fin Tube is welded by medium frequency resistance welding, the weld fusion rate is high providing good tensile strength,and good heat conduction performance, and the heat transfer area is greatly extended. TheWelded Square Fin Tube has single-tube(H type) and double-tube(HH type), wherein the single-tube fin structure is more flexible in design, and has a better cooling effect, generally used in a high temperature section. The double-tube type has better structural rigidity and can be applied to applications where longer tube is required. The fin material can be made of carbon steel or heat-resistant alloy steel depending on the temperature. WHY USE FINNED TUBES Rigid structure and higher wear life Lower flue side resistance, compact assembly, shorter breeching duct and lighter of equipment weight Square Finned Tube has better performance on anti-ash…
