Abstract

Method for shot blasting the external surface of a tube that is partially straight and partially curved, using a group of shot blast nozzles arranged concentrically around and directed towards the tube, characterized in that for the shot blasting of a straight part of the tube the group of nozzles is kept stationary and the tube is moved in a straight path with said straight part of the tube passing through the group of nozzles, while to blast a curved part of the tube, it is kept stationary and the group of nozzles is moved along the curved part.
