Definitions

  • the invention relates to a method for producing a steam generator tube with an installation body.
  • Smooth tubes or internally finned tubes are used for evaporator heating surfaces in steam generators.
  • the use of internally finned tubes may be necessary for various reasons: low full-load mass flow density of the evaporator (e.g. BENSON Low Mass Flux Design), high heat flow density and risk of film boiling (e.g. drum boiler), avoidance of flow stratification in normal load operation (e.g. minimum load in spiral-tube evaporators).
  • internally finned tubes can only be manufactured with materials with a maximum chromium content of 5%. Is the use of internally finned tubes made of higher alloyed steel e.g. due to a further increase in the steam parameters, the internally finned tubes cannot be produced with consistently good quality using the production processes available today.
  • the EP 2 390 567 A1 a method for producing steam generator tubes, in which an installation body is fixed in the grooves of a stencil shaft, the stencil shaft is inserted with the installation body into a steam generator tube, the fixation of the installation body on the stencil shaft is released and the stencil shaft is removed again from the steam generator tube.
  • the DE 10 2012 219 898 B4 finally claims a resistance spot welding apparatus for fixing a swirl body on an inner wall of a steam generator tube and discloses the use of the resistance welding method for producing a connection between the tube and the body.
  • the installation body has a high degree of rigidity and it lies largely close to the inside wall of the tube as soon as the template shaft has been turned out of the tube.
  • contact on 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 presses the wire of the installation body against the inner wall of the pipe via a hydraulic cylinder even before the welding current is switched on.
  • the object of the invention is to provide a method for producing a steam generator tube with a built-in body.
  • the object directed to a method is achieved by a method for producing a steam generator tube with an installation body, in which a steam generator tube is produced with an elevation extending in the longitudinal direction of the steam generator tube on an inside of the tube and the installation body is welded to the elevation in the steam generator tube.
  • the invention is based on the knowledge that a contact surface between the installation body and the inner tube wall is required precisely on the welding electrode so that a sufficiently good quality of the weld can be reproducibly produced. It is therefore proposed according to the invention that a comparatively small increase is produced on the inner tube wall before the swirl installation body is introduced and that the welding of the installation body takes place exactly on this elevation.
  • the increase creates a defined point at which the local contact pressure acts through the electrode and where the current flows during welding.
  • the chromium content of the steam generator tube is typically over 5%.
  • the use of steels with a chromium content of over 5% is necessary.
  • Corresponding reliable manufacturing processes are not known, so that the additional effort for the provision of such a tube is justified with an increase.
  • the increase is less than 1 mm in the radial direction in relation to the steam generator tube.
  • the increase thus remains comparatively small and essentially only has to compensate for manufacturing tolerances.
  • the steam generator tube may be produced with an increase by cold drawing.
  • the special shape of the inside it is therefore possible for the special shape of the inside to be integrated into the manufacturing process of the semi-finished product largely cost-neutral.
  • stamp the elevation with a stamp, in particular with a hydraulic stamp.
  • the installation body is spiral and is welded to the elevation in several places. This can also be used for comparative purposes high steam parameters an internally finned steam generator tube can be produced.
  • the Figure 1 shows schematically and by way of example a steam generator tube 1 for the production of an in Figure 2 shown steam generator tube 2 with a spiral installation body 3rd
  • Figure 1 extends an increase 5 in the axial direction of the steam generator tube 1, namely how Figure 2 shows, over the entire area in which the spiral installation body 3 is arranged.
  • the installation body 3 is welded to the elevation 5 at several contact points 6.
  • FIG 3 shows schematically the individual steps of the manufacturing method according to the invention.
  • step A a steam generator tube 1 is produced with an elevation extending in the longitudinal direction of the steam generator tube on an inside of the tube, for example by means of cold drawing.
  • step B the installation body 3 is then first introduced and then welded in step C in the steam generator tube 1 on the elevation 5, so that a steam generator tube 2 with the installation body 3 is produced.
  • step B the installation body 3 has several turns, it is also welded at several contact points 6 between swirl installation body 3 and elevation 5.
