Definitions

  • the invention relates to a method for producing steel pipes, in which a sheet metal or coil formed in a bending process to a round tube in cross-section, welded in a subsequent welding along the longitudinal edges facing each other for producing a longitudinal seam and then subjected to a relaxation treatment.
  • a method of this kind is in the DE 10 2006 010 040 B3 specified.
  • the tube is compressed by means of a straightening machine from the outer circumference by means of a plurality of circumferentially offset, axially arranged rectilinear straightening for straightening, the straightening wear the straightening tube adapted to the shape of the tube outer cross section.
  • the straightening can be individually or in dependence on each other z. B. are moved hydraulically, the operation can be controlled or regulated can.
  • the straightening cylinders with the straightening shells can direct the tube up to its circular contour, the calibration taking place with respect to the diameter and / or the ovality. An upsetting of the material beyond the yield point is also possible by means of this so-called impanding there for the first time.
  • the EP 0 438 205 A2 shows a method and apparatus for straightening the ends of elongated workpieces.
  • the workpiece is stationary, at least one selected in the end region cross-section of a rising and falling bending bending stress is subjected, with a predetermined maximum deflection one or more times revolves around the workpiece axis.
  • a rising or falling bending stress is chosen so that the selected cross section is deformed into the plastic region.
  • the means for generating a deflection of the workpiece axis in an orbit beyond the elastic limit of the workpiece also have at least three symmetrically arranged about a common axis, movable in the radial direction plunger, which are each connected to a path and time-dependent controllable piston-cylinder unit and the rams out of phase with each other during the straightening process by means of a control connection of the piston-cylinder units to perform a sinusoidal lifting movement. This is done no judging roundness or ovality, but a correction of deviations in the straightness of the bent ends, ie it is about a longitudinal straightening.
  • FR 737 123 A shown straightening machine for pipes they are directed in their longitudinal direction, in a warm state.
  • the straightening elements are z. B. rounded according to the diameter of the tube, wherein the inner part of the straightening elements can be interchangeable.
  • the tubes are heated red and evacuated. After the longitudinal straightening thus carried out, the tubes are fed by means of an ejector to a cooling device.
  • the straightening of large steel pipes is complicated with such measures, and problems and solutions to Rundricht do not go out of this document.
  • DE 196 02 920 A1 is a method for producing pipes, in particular large pipes, specified, in which the tubes are calibrated and straightened after the internal and external welding by cold expansion (expanding).
  • the DE 41 24 689 A1 shows a method and apparatus for eliminating molding defects and eliminating noxious residual stresses in longitudinally welded tubing also by expanding the tube using an internal mandrel. The expansion of the tubing takes place in such a measure that existing in the circumferential direction residual stresses should be largely eliminated.
  • the tools During expansion, the tools generate a uniform force on the inner side of the tube, which, when straightening, evenly guides the material into a circular shape. In this process, however, unfavorable stress conditions can be generated in the tubular body, whereby the compression strength and thus collapse resistance of the pipe can decrease.
  • coated pipes eg CLAD pipes
  • the material may also be damaged so that such pipes often can not be calibrated using this process. Such adverse effects can be further increased with increasing degree of expansion.
  • the invention has for its object to provide a method for producing large steel tubes, with which the production of high-quality pipes is achieved with the most accurate rounding and with the shortest possible production time, as well as appropriately trained pipes to provide, including the mechanical technological properties of the material to be improved.
  • the relaxation treatment is performed in a step to Rundricht along the circumference at least partially with respect to the longitudinal axis of the tube under cold deformation by upsetting.
  • the target diameter can be set well, but in the process of Rundhouses is also a Relaxation treatment performed.
  • the pipe tolerance in particular the ovality, improved by uniform plastic deformation of the material in a short time, but also the residual stress behavior of the tubular body.
  • the stresses generated mechanically by the shaping of the sheet metal material in the base material are reduced, but also the thermally generated stresses caused by the longitudinal seam welding of the sheet material formed to the tube are reduced.
  • the mechanical properties of the pipe are improved by the method, namely z. B. the compression strength and the collapse resistance.
  • the residual stress behavior after impanding is reduced to a minimum, whereby a virtually complete reduction in stress is made possible without a complex heat treatment (low-stress annealing at, for example, approx 600 ° C) is required, and disadvantages caused by the heat treatment can be avoided.
  • Due to the uniform upsetting over the outer surface of the tube the residual stresses generated by the manufacturing process in the longitudinal and circumferential direction in the base material and in the weld build off.
  • a reason for the improvements obviously lies in the fact that the residual stress state is reversed, ie after the impanding there is tension on the inside of the tube and compressive stress on the outside of the tube.
  • a measure which is advantageous for the straightening and the relaxation is that during straightening a plastic deformation of the tubular body is made over its entire circumference.
  • Vorteihafte embodiments for an exact Rundbox consist in the fact that the circular alignment is done on predetermined pipe outside diameter or predetermined pipe inside diameter.
  • the measures further contribute to the fact that circumferential straightening and hydraulic expansion (for example with hydrotester) are combined with each other during straightening for relaxation.
  • the impanding and hydraulic relaxation can also be carried out alternately and repeatedly.
  • the straightening and the relaxation processes are facilitated by the fact that the straightening and relaxing is carried out by means of at least two straightening dies, which are pressed from outside in the radial direction to the tube axis and offset in the circumferential direction, with straightening cups which are adapted in sections to the peripheral contour of the tube.
  • a tube having advantageous properties is obtained by being produced by one of the above-mentioned methods.
  • Fig. 1 shows an axial plan view of a tube 1 of a round cross-section with an inner radius r i and an outer radius r a , through whose difference a wall thickness t is fixed.
  • the tube 1 has a longitudinally extending weld seam 2.
  • Mechanical or thermal stress regions 3, 3 ' are present in the tube wall on the one hand as a result of the mechanical molding process and on the other as a result of the heat influences during welding.

  • the straightening cups 11, 12, 13, 14 only over a short section of the tube 1, wherein a plurality of such units of straightening cups 11, 12, 13, 14 can be arranged in the longitudinal direction of the tube 1 on the outer surface.
  • the holder 15 of the straightening shells 11, 12, 13, 14 are along a Guide axis 17 hydraulically adjusted in radial, oriented to the center of the tube 1 direction in the carrier 16 to cause a compression of the tubular body and a hydraulic expansion in the opposite direction under control or regulation by means of a control device 20.
  • a directing to predetermined inner or outer diameter can take place, wherein an absolute position can be specified via the control device.
  • Fig. 2 shows essential steps in the manufacture of the tube 1, namely a molding process a, in which a metal plate 4 is formed by means of a molding device 30 by means of dies under advancement of the metal plate 4 gradually to a bent part 1.1 and finally the circumferentially bent tubular body 1.2. Subsequently, the tubular body 1.2 is closed in a welding process b at its mutually facing edges, which were previously prepared for welding, by means of a longitudinal weld in a welding device 40.
