Definitions
- the invention relates to a steam generator tube for the production of a steam generator tube with mounting body and a method for producing a steam generator tube with mounting body.
- the internal ribbing of the tubes is made according to the prior art by a cold drawing process.
- ⁇ nisstand inner finned tubes can be made 5 "6 only with materials with a maximum chromium content ⁇ . If the use of internally ribbed tubes made of high alloy chrome steel for example, by a further increase of the steam parameters necessary, the inner grooved tubes with the can production processes available today are not produced with consistently good quality.
- WO 2011/151135 A2 discloses the manufacture and assembly of a spin fit body in a smooth evaporator tube.
- EP 2 390 567 A1 discloses a method for producing steam generator tubes, in which an installation body is fixed in grooves of a template shaft, the template shaft with the installation body is introduced into a steam generator tube, the fixation of the installation body on the template shaft is released and the stencil shaft is removed again from the steamer ⁇ zeugerrohr.
- the DE 10 2012 219 898 B4 finally occupies a Wi derstandsyak spaapparat for fixing a twist ⁇ mounting body on a inner wall of a steam generator tube and discloses the application of the resistance welding method for producing a connection between the pipe and fitting body. It turns out, however, that the quality of the achieved
- the mounting body has a high rigidity and it is largely close to the pipe inner wall as soon as the stencil shaft was rotated out of the pipe.
- the contact with the pipe wall is not guaranteed at all points due to tolerances of the pipe and the installation body.
- the electrode of the welding lance pressed against the wire of the mounting body to the tube inner wall above ei ⁇ NEN hydraulic cylinder before switching on the welding current. Nevertheless, there is no guarantee that exactly and only to the welding electrode, an electrically conductive contact surface Zvi ⁇ rule is made installation body and the pipe inside.
- the object of the invention is to provide a steam generator tube, with a consistently good quality of
- Another object of the invention is to provide a corre sponding ⁇ method.
- the invention solves the addressed to a steam generator tube task by providing that, in such a steam generator tube ⁇ for the production of a steam generator tube with a spiral-shaped mounting body on the inside of the
- Steam generator tube extends an increase in the axial direction of the steam generator tube.
- the invention is based on the realization that a contact area between ⁇ mounting body and inner pipe wall is exactly required at the welding electrode, so that adequate gu ⁇ te quality of the weld advertising reproducibly prepared the can. According to the invention it is therefore proposed that a comparatively small increase is produced in the inner tube wall prior to the introduction of the swirl mounting body, and that the welding of the mounting body is carried out exactly on this raised stabili ⁇ hung.
- the local contact pressure acts on wel ⁇ cher through the electrode and flowing in the welding current is produced.
- the chromium content of the steam generator tube is more than 5%.
- Steam generator tubes for steam generators with comparatively high steam parameters require the use of steels with a chromium content of more than 5%. Corresponding reliable manufacturing processes are not known, so that the extra effort for the provision of such a pipe is justified with increase.
- the increase is less than 1 mm in the radial direction relative to the steam generator tube. The increase thus remains relatively small and must essentially compensate only for manufacturing tolerances.
- the increase extends over an area in which an installation body is to be arranged in the steam generator tube. This ensures that optimum welding conditions exist at each welding point.
- the object directed to a method is achieved by a method for producing a steam generator tube with
- the steam generator tube is made with increase by cold drawing. In a large-scale process, it is thus possible that the special shape of the inside is largely integrated cost-neutral already in the manufacturing process of the semifinished product.
- stamp the increase with a stamp in particular with a hydraulic stamp.
- the installation body is spiral-shaped and is welded at several points on the elevation 5.
- an internally referenced steam generator tube can be produced even for comparatively high steam parameters.
- Figure 1 shows an inventive steam generator tube with raised stabili ⁇ hung
- Figure 2 shows an inventive steam generator tube with spiral ⁇ shaped body
- FIG. 3 shows a flowchart of the method according to the invention 1 shows schematically and by way of example a steam generator tube 1 for the production of a steam generator tube 2 shown in FIG. 2 with a spiral installation body 3.
- an elevation 5 extends in the axial direction of the steam generator tube 1, namely Figure 2 shows, in which the spiral installation body 3 is arranged over the GESAM ⁇ th region.
- the mounting body 3 is welded at a plurality of contact points 6 with the elevation 5.
- FIG. 3 shows schematically the individual steps of the manufacturer ⁇ averaging method according to the invention.
- step A is a steam generator tube 1 with a longitudinal direction of the
- step B of the mounting body 3 is initially introduced and then published in step C in the steam generator tube 1 on the elevation 5 welded, so that a steam generator tube 2 with installation body 3 is formed.
- a swirl installation body 3 having a plurality of turns, it is also at a plurality of contact points ⁇ 6 between swirl mounting body 3 and 5 increasing welded.
