Definitions

  • the present invention relates to a method for performing the serpentinage tubes constituting the tube of a steam generator beam, in particular a steam generator sodium-water-type u "used in a fast neutron nuclear power station.
  • the invention also relates to the device enabling this serpentine to be produced in accordance with the method.
  • Certain steam generators comprise a tubular bundle made up of a plurality of tubes wound helically around a cylindrical hub, these tubes thus constituting around the hub several concentric layers regularly spaced apart.
  • a tube bundle there are also provided between each layer of tubes, support pieces intended to keep all of the tubes regularly spaced.
  • the invention therefore aims to overcome the drawbacks mentioned above, in order to allow the construction, under good conditions, of a steam generator of the "sc dium-water" type generally used in a fast neutron nuclear power plant.
  • the present invention relates more precisely to a method of serpentinizing the tubes constituting the tubular bundle of a steam generator, the tubes having to be wound helically around a cylindrical hub, in several successive concentric layers regularly spaced apart.
  • this method consists in constituting a plurality of straight tubes, then bending one of the end parts of each of these tubes, the radius of curvature thus obtained substantially corresponding to the radius of winding of the tube , then fix the end of the curved part of one or more tubes on the cylindrical hub or on a part linked to the cylindrical hub, then animate the hub with a simultaneous movement of rotation and longitudinal translation in order to wind the tube (s) in a spiral around the hub, during this winding operation the straight part of the tubes being guided, in the vicinity of the hub, using guide elements mounted fixed, and finally to bend on the hub l another end of the tube or tubes which have just been wound simultaneously, in order to complete the winding.
  • the invention also relates to the device making it possible to set up works the serpentine method which is the subject of the invention.
  • this device essentially consists of a machine comprising a frame provided with rollers rolling on rectilinear rails, a motor pinion engaged on a rectilinear rack parallel to the rails, a rotating spindle drive coupled to the cylindrical hub of the steam generator, support rollers arranged at both ends of the cylindrical hub, allowing the hub to rotate about its axis arranged parallel to the rails, and a transmission establishing a constant relationship between the rotation of the spindle and that of the drive pinion, in order to obtain the simultaneous movement, of constant ratio, of rotation of the hub and of translation of the whole of the machine supporting the hub, the transmission ratio being determined as a function of the angle of inclination of the helical winding of the tubes around the hub.
  • the object of the invention is to produce the helical tube bundle of a high power steam generator.
  • the first operation consists in producing a large number of straight tubes 1 of great length. This length of the tubes can be, for example, of the order of 100 meters.
  • These tubes 1 are generally produced from several sections of tubes connected end to end by welds 2, 3. Once these tubes have been produced and stored, one of these tubes is seized and a bending operation is carried out on one of its ends so that the curvature thus obtained has a radius equal to the radius of winding of the tube on a hub. Then, as shown in FIG. 4, this tube is thus bent on the cylindrical hub 4 of the steam generator, mounted on a machine 5.
  • the end 6 of the tube is attached to the hub 4, near one of the ends of the hub, and there is, on the rectilinear part of the tube, in the vicinity of the machine 5, a guide 7 mounted fixed relative to the ground 8.
  • a guide 7 mounted fixed relative to the ground 8.
  • the part of the tube bent before the winding of the tube around the hub ( Figure 3) the shape of a helix whose angle of inclination is identical to that of the helical winding of the tube around the hub.
  • This part of the tube bent before the tube is wound around the hub may extend, preferably, approximately half a turn.
  • Cam shown in Figure 2 before any tube bending operation, one can form a short distance from the ends of the tubes of the elbows so that each tube, once wrapped around the hub, has its two ends oriented longitudinally relative to the hub.
  • FIGS. 7 to 9 there will be described a device making it possible to serpentine the tubes constituting the tubular bundle of steam generator according to the method which has been described previously.
  • This device essentially consists of a machine 11 which comprises a frame 12 provided with rollers 13 rolling on rails 14 rectilinear and parallel, a driving pinion 15 engaged on a rack 16 rectilinear parallel to the rails, a rotating spindle 17 driving coupled to cylindrical hub 4 of the steam generator, and support rollers 18 disposed at the two ends of the cylindrical hub 4, allowing the hub 4 to rotate about its axis 9 arranged parallel to the rails.
  • the machine further comprises a transmission establishing a constant ratio between the rotation of the spindle 17 and that of the drive pinion 15, in order to obtain the simultaneous movement of constant ratio between the rotational movement of the hub 4 and the translational movement of the 'assembly of the machine 11 supporting the hub 4, the transmission ratio being determined as a function of the angle of inclination of the helical winding of the tubes around the hub.
  • the machine may further include a secondary frame 19 which can move longitudinally relative to the frame 12 of the machine while being guided using slides 20, this frame 19 being intended to support a part 21 constituting a guide for the tubes. to roll up.
  • a secondary frame 19 which can move longitudinally relative to the frame 12 of the machine while being guided using slides 20, this frame 19 being intended to support a part 21 constituting a guide for the tubes. to roll up.
  • the machine 11 operates in the following manner: after bending the end part of the tubes, hook their end 6 on the hub 4, then start the machine which rotates the hub 4 while moving longitudinally, which causes the helical winding of tubes around the hub 4.
  • the rotation of the drive pinion 15 is stopped, in order to stop the longitudinal movement of the machine 11, the guide 21 is moved so as to bring it into contact with the unrolled end of the tubes, then continue to rotate the hub 4 by longitudinally moving the frame 19 supporting the guide 21 relative to the frame 12 of the machine. In this way, the helical winding of the tubes can be carried out as close as possible to the end of the hub 4.
  • the free end of the tubes is then bent in order to completely end their winding around the cylinder, this bending giving the tube a helical shape identical to that of winding the tube around the hub.
  • the different plies of tubes are held in place by means of parts supports 25. If, during the winding of the tubes has only the support parts 25, the tubes may not take a perfectly circular shape because one cannot have a very large number of support parts 25 over the entire periphery. It is then possible to have, between two consecutive support pieces 25, pieces 26 arranged longitudinally, over the entire length of the hub 4, these pieces 26 having the shape of a flattened bar. A large number of these bars 26 are thus arranged all around the layer of previously wound tubes, their median plane being arranged radially.
