<p>PURPOSE: A method for manufacturing a fin-tube for a waste heat recovery boiler, capable of rapidly welding a fin with a tube, is provided to improve welding quality by increasing welding accuracy and by preventing poor welding. CONSTITUTION: The outer surface of a long tube(T) made of one of carbon steel, P235GH, T11, T22, T23 and T91, is roughed. A fin-tube for a waste heat recovery boiler is manufactured by winding a strip type fin(F) along the outer surface of a tube by rotating the tube. The fin is made of carbon steel or T409. The fin is serrated type and keeps an inter-fin distance 8.38-8.81 inch.</p> |
