A method for producing a steam generator pipe having an installation body.
Claims5
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.
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.
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.
