Abstract: Pilger rolling mill for working a hollow into a tube has a first roll stand mounted linearly moveable in a direction of motion. Translational motion of the roll stand causes rotational motion of the drive gear due to the cogging of the drive gear with the gear rack and, hence, also rotational motion of the roller arranged on the shaft of the drive gear and rotational motion of the other one of the two rollers in the opposite direction. Roll stand is connected with a crank drive and rotational motion of a motor drive is transformed into an oscillating translational motion of the roll stand by a connecting rod. Gear rack holder allows adjustment of the pilger rolling mill with respect to tube diameters of finished rolled tubes by arranging the first roll stand exchangeable by a second roll stand with a second dimension being different from the first dimension.

Abstract: The present invention relates to a method for forming a hollow 26 of a ferritic FeCrAl alloy into a tube 2. While tubes made of powder metallurgical, dispersion hardened, ferritic FeCrAl alloys are commercially available, hollows made of FeCrAl alloys so far can hardly be formed into tubes of small dimensions. The major reason for the problems in forming hollows of a ferritic FeCrAI alloy into a finished product is that FeCrAl alloys are brittle. It is therefore an aspect of the present invention to provide a tube 2 made of a ferritic FeCrAl alloy having arbitrary small dimensions. Furthermore, it is an aspect of the present invention to provide a machine 1 and a method for forming a tubular hollow 26 into a finished tube 2 of a ferritic FeCrAl alloy. At least one of the above aspects is addressed by a method for forming a hollow into a tube 2 comprising the steps providing the hollow 26 of a ferritic FeCrAl alloy, heating the hollow 26 to a temperature in a range from 90° C. to 150° C.

It is detrimental that protection of the sensors at these tubes against environmental influences is complex. In contrast, it is an object of the present disclosure to provide a method for manufacturing a tube, in which the signal line can be protectively mounted. To solve this object, a method for manufacturing a tube of metal is suggested with an outer tube and an inner tube, wherein a groove is drawn in an inner surface of the outer tube or in an outer surface of the inner tube and subsequently the inner tube and the outer tube are drawn together through a drawing die, wherein the inner dimension of the outer tube is reduced such that after the drawing the outer tube is force-fitted onto the inner tube.
