A method for producing a steam generator pipe having an installation body.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing a steam generator pipe comprising an installation body, the method comprising: producing a steam generator pipe comprising an elevation which is an integrally formed portion of the steam generator pipe and which extends in a longitudinal direction of the steam generator pipe on a pipe inner side, and welding the installation body on the elevation in the steam generator pipe such that the installation body is positioned radially inward of the elevation with respect to a longitudinal axis of the steam generator pipe, wherein the steam generator pipe comprising the elevation is produced by a cold drawing process that forms the elevation as the integrally formed portion of the steam generator pipe. 2. The method according to claim 1 , wherein the installation body is spiral-shaped and is welded on the elevation at multiple contact points. 3. A method, comprising: cold drawing a steam generator pipe comprising an elevation which is integrally formed in the steam generator pipe as part of the cold drawing, wherein the elevation extends in a longitudinal direction of the steam generator pipe on a pipe inner side, and welding an installation body on the elevation such that the installation body is positioned radially inward of the elevation with respect to a longitudinal axis of the steam generator pipe. 4. The method of claim 3 , wherein a radial height of the elevation is not greater than one millimeter. 5. A method for producing a steam generator pipe comprising an installation body, the method comprising: producing a steam generator pipe comprising an elevation which is an integrally formed portion of the steam generator pipe and which extends in a longitudinal direction of the steam generator pipe on a pipe inner side, and welding the installation body on the elevation in the steam generator pipe such that the installation body is positioned radially inward of the elevation with respect to a longitudinal axis of the steam generator pipe, wherein the installation body is spiral-shaped and is welded on the elevation at multiple contact points.
