  • the multilayer pipes are coated with a corrosion protection.
  • the tubes are brought to an elevated temperature (in a range of about 250 to 270 ° C). This is problematic for such multi-layer pipes, since stainless due to the different coefficients of thermal expansion of the existing usually made of carbon steel outer pipe (10.5 x 10 -6 K "1) and the high alloyed austenitic material of the inner tube, such.

  • the outer tube or carrier tube withstands high mechanical loads from inside (internal pressure) and outside (external pressure, eg in deep-sea applications, landslides, earthquakes).
  • the inner tube must withstand aggressive transported media.
  • both the inner tube and the outer tube must form circumferentially fully closed tight sheaths, which is ensured by the closed inner tube and the closed outer tube.
  • Possible approaches include forming the wavy contour into a finished longitudinally or spirally welded or seamless tubular body.
  • An advantageous procedure also consists in that the wave-shaped contour is already formed in the flat starting state in the support plate.
  • a firm frictional connection between the outer tube and the inner tube is achieved in that in the unstretched state before expanding a circumferentially measured outer peripheral length of the corrugated inner tube is selected, which exceeds the length of a smallest possible circle, which surrounds the inner tube from the outside, and the outer circumference length is selected to be at most so large that after expansion and elimination of the expansion force just no wrinkling of the inner tube occurs.
  • the concept of the circle should not be understood strictly mathematically, but also encompass non-circularities occurring in practical production, in particular ovalities, which form an envelope around the peaks (maxima).

  • This offers particular advantages in the event that the expansion takes place in the case of a pipe which is already provided with a coating which forms an anti-corrosive coating, because no external die is required for catching the outer pipe 1, as a result of which the outer coating could be damaged.
