Abstract
THERE IS DISCLOSED AN APPARATUS FOR ROLLING METAL PIPE WHICH INCLUDES A PLURALITY OF ROLLING BALLS (11) DISRIBUTED AROUND THE METAL PIPE (12) AND AN EXTERNAL RING (13). THE EXTERNAL RING (13) SERVES TO SUPPORT AND BRING THE ROLLING BALLS (11) INTO INTIMATE CONTACT WITH THE METAL PIPE (12) WHILE IMPARTING A ROLLING MOTION TO THE BALLS (11) BY MEANS OF POINT CONTACT BETWEEN THE RING'S CIRCUMFERENTIALLY ROTATING INNER SURFACE AND THE ROLLING BALLS (11). THE DISTANCE D BETWEEN ADJACENT ROLLING BALLS (11) IS SET TO SATISFY THE FOLLOWING RELATIONSHIP:WHERE D, D AND N DENOTE THE OUTER DIAMETER OF THE ROLLING BALLS (11) THE OUTER DIAMETER OF THE METAL PIPE (12) AFTER THE ROLLING PROCESS, AND A SPEED OF ROTATION OF THE ROLLING BALLS (11), RESPECTIVELY (FIG. 3)(FIG. 3)
