Abstract: A process of making round tubes covered on the inside with a sleeve of a thickness on the order of 20 to 30% of the total thickness of the tubes. The components of the tube consist of steel of strong mechanical characteristics and of an interior of stainless steel or a noble alloy. Both components are united by means of metallurgic cohesion, the result of which is a single tube, in effect. The making of the combined tube is achieved by reforming, piercing and extrusion at the same temperature.

Abstract: The apparatus comprises a disk shaped shut-off flap located in the passage of a main body. The shut-off flap is mounted such to a rocking shaft that the flap can be lifted off its seat during one phase of movement of the rocking shaft and may be rotated into an open position during a further phase of movement of the rocking shaft. The operating means comprises a linear drive in the shape of a control rod including a control groove. A follower and driving means engages the control groove and the shut-off flap. Accordingly the shut-off flap is guided for above lift off and rotating movements. This linear drive allows an impeccable sealing between the inner space of the shut-off apparatus and the environment.
