in the mandrel mill process, a solid round (billet) is used. it is heated in a rotary hearth heating furnace and then pierced by a piercer. the pierced billet or hollow shell is rolled by a mandrel mill to reduce the outside diameter and wall thickness which forms a multiple length mother tube. the mother tube is reheated and further reduced to specified dimensions by the stretch reducer. the tube is then cooled, cut, straightened and subjected to finishing and inspection processes before shipment.
