摘要： An exemplary embodiment of the invention provides a method for producing an ultra thin wall metallic tube by cold working method with significant wall thickness reduction. In a method for producing the metallic tube with a cold pilger mill according to the invention, cold rolling is performed while tube diameters are being expanded using rolls having tapered groove dies whose calibers increase from an engaging entry side toward a finishing exit side. In a method for producing the metallic tube with a drawing machine according to the invention, cold drawing is performed while the tube diameters are being expanded using a solid die whose calibers increase from an engaging entry side toward a finishing exit side and a plug of a tapered mandrel bar whose diameters increase from an entry side of the die toward an exit side. In the metallic tube producing method, a maximum diameter of the plug or tapered mandrel bar may be larger than an outside diameter of the mother tube.

摘要： A method for manufacturing seamless steel tubes by the Mannnesmann tube making process wherein a billet is passed through a piercer and the center of the billet is pierced through to obtain a hollow shell. A pair of disk rolls are disposed to incline by a skew angle .delta. with respect to a pass line toward cone-type main roll located at the entry side, where a material to be rolled enters into the disk roll sliding face, thereby to become unparallel with the outlet face angle of the main roll, while the skew angle .delta. is set to satisfy the following conditions related to the skew angle .delta., the inlet face angle .theta.1 and the outlet face angle .theta.2 of the main roll, thereby to obtain expansion ratio of outer diameter of 1.15 or higher value..theta.2+2.degree.
