摘要： A method for producing a tube of a nickel-based alloy tube which comprises the steps of hot working a nicked-based alloy casting into a pretubular-shaped workpiece or into a cylindrical bar, trepanning the cylindrical bar or machining an inner diameter of the pretubular-shaped workpiece to obtain a tubular workpiece, and cold working the tubular workpiece. The hot working comprises one of: rolling, forging, and a combination thereof. The cold working comprises flow forming or pilgering. A nickel-based alloy tube produced with the method comprises an outer diameter greater than or equal to 60.3 mm, an average wall thickness greater than or equal to 2.8 mm, and less than or equal to 70 mm.

摘要： Method for bending tubular articles (1a) with a relative ratio of the bending radius (R) and the outer diameter (D) of the finished pipe which is less than 3, comprising the following steps:
- forging an article (1a) made of material with a predefined composition depending on the final use and with a predefined length (L) in the longitudinal direction and an outer diameter (D);
- preparing a die (100) comprising:
· an asymmetrical bottom die half (110) with seat (111a) for the pipe (1a); and
· a top die half (120) with punch (121) asymmetrically arranged in the longitudinal direction (X-X) with respect to the vertical centre axis of the die;

- heating the pipe in an oven to the required temperature for forging depending on the specific composition of the material;
- positioning the article (1a) inside the bottom die half (110) in the longitudinal direction;
- relative closing of the two die halves (110,120) so as to start bending of the article (1a);
- opening the die;
- extracting the bent pipe.
