The invention relates to a rolling mill for tubes, in which a series of roll-holder containers ( 10 ) is housed in an external structure ( 2 ) extended along a rolling axis (L); the containers can slide inside the structure to be extracted therefrom and each one houses at least three rolls ( 17, 18, 19 ) controlled by respective driving motors ( 41, 42, 43 ). In accordance with the intervention the rolls ( 17, 18, 19 ) can be moved inside the containers ( 10 ) in a guided way along directions radial in relation to the rolling axis, in order to regulate the distance therefrom.
