Definitions

  • the present invention relates to a method for producing a large-diameter and thick-walled steel pipe used for a line pipe or the like.
  • a steel plate with a predetermined width, length and thickness is press-formed into a U-shape and further into an O-shape.
  • a so-called UOE steel pipe whose roundness has been increased by pipe-expanding to increase the diameter of the above-mentioned steel pipe by welding the butting part (welding the seam) to a steel pipe.
  • a large-scale press is required because a large pressing pressure (press force) is required in the process of pressing the steel sheet into a U-shape or O-shape. It is necessary to use a machine (press machine).
  • the number of three-point bending presses is increased, the roundness of the obtained steel pipe is improved, but the productivity (productivity) is reduced because it takes a long time to manufacture the steel pipe. . Conversely, if the number of three-point bending presses is reduced, productivity is improved, but the roundness of the steel pipe is reduced. Therefore, the actual situation is that the number of three-point bending presses is empirically set to 50 to 60 times for a steel pipe having a diameter of 1200 mm, for example, according to the dimensions of the steel pipe.
  • the number of the three-point bending presses is set to (aN-1) times (where a is an integer such as 1, 2), where N is the number of the tube expansion tools.
  • the present invention when manufacturing a large-diameter and thick-walled steel pipe by performing three-point bending press molding, it is not necessary to heat the steel pipe, and the number of three-point bending press can be reduced. It is possible to manufacture a steel pipe with excellent roundness with high productivity without impairing excellent properties such as strength, toughness, and weldability built in the manufacturing process.
  • FIG. 1A After bending both width end portions (width L) of the steel plate 3 having a plate width W shown in FIG. 1A to form a bent portion (hereinafter referred to as “end bending”), FIG. ), One half of the width center line CL is subjected to a three-point bending press 4 a plurality of times from one width end side of the steel plate 3 toward the width center (however, the width center line CL portion remains) ), One half of the steel plate 3 is formed into a substantially circular shape.
  • a plurality of three-point bending presses 4 are performed at equal intervals on the remaining half of the width center line CL of the steel sheet (however, the width center line CL portion is
  • the steel plate 3 is formed into a substantially semicircular arc shape.
  • both width ends of the steel plate 3 are butted by performing a three-point bending press 4 at the position of the width center line CL, and then the butt is welded.
  • the raw tube 1 shown in 1 (e) is obtained.
  • the pipe expanding device including a plurality of pipe expanding tools
  • the pipe is expanded by bringing the arcuate curved surface of the pipe expanding tool into contact with all undeformed portions. To do.
  • the deformation of the deformed portion that does not contact the tube expansion tool is suppressed, and the undeformed portion is preferentially deformed, so that the undeformed portion is connected to the deformed portion that has already been formed into an arc shape.
  • the number of undeformed portions of the raw tube is the same as the number of tube expansion tools of the tube expansion device inserted into the raw tube. . That is, when the number of tube expansion tools is N, it is preferable to perform a three-point bending press so that the undeformed portion of the raw tube also has N locations. In this case, one butt weld and (N-1) deformed portions are arranged in a gap between N tube expansion tools. In this case, the number of three-point bending presses may be (N-1) times.
  • FIG. 3 an example in which the number of undeformed portions 9 and the number of tube expanding tools 2 are the same, that is, an element tube 1 subjected to 11 three-point bending presses is replaced with 12 tube expanding tools 2.
  • the number of three-point bending presses 4 applied to the material steel plate is half of one side of the width center line CL shown in FIG.
  • the opening angle (arc angle) of an arc having a radius of curvature of 580 mm which is in contact with the inner surface of the tube of the tube expansion tool was 33.4 ° (when the number of tube expansion tools is 10, the same applies hereinafter).
  • the steel pipe C (invention example) was manufactured by performing a three-point bending press 19 times as shown in Table 1 to produce a raw pipe having 20 undeformed parts, as shown in Table 2.
