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: Method for producing a high-pressure tube with inner tube and outer tube made of metal are drawn together through a first drawing die. The outer diameter of the inner tube is smaller than the inner diameter and drawing forms a very stable frictional connection between the inner tube and the outer tube. The manufactured tube has a large wall thickness and is very robust and pressure-resistant while having a very high quality outer shell surface and in particular a very high quality inner shell surface by virtue of the cold forming process. These two properties allow a sufficiently high protection against bursting when pressures in excess of 12,000 bar are applied to the tube. The produced tube has improved dynamic pressure resistance against high pressures by combining a large wall thickness of the tube to be manufactured with a high quality inner shell surface of the tube to be manufactured.
