rangement is still widely used on large mills. (A) The five roll box (B) is a variation in this desgn that adds a fifth roll at the bottom of the tube, allowing smaller diameter side rolls to be used. Many smaller mills use three rolls mounted 120 degrees apart. Some are orientated with a grooved roll at the top of the tube (D), others with a roll

Basic Principles of Tube Expanding Tube Expanding is the art of reducing a tube wall by compressing the O.D. of the tube against a fixed container . . . such as rolling tubes into tube sheets, drums, ferrules or flanges. To assure a proper tube joint, the tube wall must be reduced by a predetermined percentage.
