Abstract: A finning and thread rolling machine capable of producing an integral finned tube, an extended finned tube or a wrap-on finned tube, whichever is desired, the tubing to be used for extended surface heat transfer. Types of tubes produced are integral low finned tube, bi-metal fin tube with extruded high finned tube on the outer portion, and extruded integral/high finned tube and spiral strip helical wrap-on finned tube. The apparatus also provides a two and three die thread rolling machine for thru-feed threading and form rolling.
