ABSTRACT:
A method of forming ribs on tubes or pipes is characterized by applying to the material of the tube, from which the rib is formed, initial compressive stresses preferably ##EQU1## where Fo denotes the area of the cross-section of the tube before drawing, Fr denotes the area of the cross-section of the core of the tube after drawing the rib, and Re is the plasticity limit. Next, ribs are drawn by driven tools with roll-formed disks while maintaining said compressive stress.
