Mandrel bars are used in the production of seamless tubes and pipes. They are inserted into the hollow tube during the manufacturing process to provide internal support and maintain the shape of the tube as it is being rolled or drawn. This helps to ensure a consistent diameter and wall thickness throughout the length of the tube.
