Abstract

1,202,105. Rolling tubes. VALLOUREC. 17 May, 1968 [18 May, 1967], No. 23738/68. Addition to 1,150,582. Heading B3M. A tube is produced from a blank by rolling the blank in a mill of the type described in Specification 1,150,582 to a profile as shown in the accompanying figure, the centre section 4 of the blank having a uniform thickness. The mill includes rolls surrounding the tube and extending generally longitudinally between respective fixed and a movable apertured plates. Rotation of the movable plate varies the angle of skew of the rolls and the working diameter of the pass they define. The thickened ends of the blank are parted off and the tube is progressively reduced in several stands having toroidal rolls 7 to its final thickness. The resulting and fractions of tube which have to be discarded are of shorter length than is usual.
