Definitions

  • the present invention relates to a multilayer pipe according to the preamble of claim 6 and a method for its preparation according to the preamble of claim 1 (each case eg US-A-3327383 , Multilayer pipes are preferably used in case of high requirements against corrosion or abrasion.
  • Corrosion-resistant pressure vessels or pressure lines can be made more cost-effective by using multilayer pipes than solid forms made of appropriate materials. This is achieved by the load sharing on a thin, corrosion resistant inner layer (e.g., stainless and acid resistant steel) and a high strength, pressure resistant outer layer (e.g., fine grain structural steel). As a result, overall steel consumption can be significantly reduced and much of the remaining steel consumption can be shifted to low-cost materials.
  • a thin, corrosion resistant inner layer e.g., stainless and acid resistant steel
  • a high strength, pressure resistant outer layer e.g., fine grain structural steel
  • Abrasion-resistant pipes are made possible by the design as a multilayer pipe (such as mechanical bond, see below) in certain grades in the first place, because materials (eg high-strength steels with high hardness) can be used as an inner layer, which alone or only very difficult can be processed into tubes.
  • the use of rolled and / or blast-plated semifinished product can be avoided that the respective acting as an inner tube material layer pressed during tube formation in the bending roll and / or the final shaping usually necessary Anbiegemaschine frictionally in the respective functioning as outer tube material layer and is frictionally held in the respective outer tube and without having to expand the multilayer tube and thus to take the disadvantages already mentioned.
  • Anbiegemaschine frictionally in the respective functioning as outer tube material layer and is frictionally held in the respective outer tube and without having to expand the multilayer tube and thus to take the disadvantages already mentioned It should be noted that in some cases, however, a final forming in the bending roll alone is possible, such as shorter bending rolls, which can perform the function of the final shaping of the tube with. In these cases, a bender does not participate in manufacturing processes.
  • the multilayer pipe is closed by welding the outer pipe along the pipe seam and build-up welding of the inner pipe so as to manufacture the multilayer pipe body.
  • the material layers can be connected to the front sides of the tube, for example, there to prevent the ingress of moisture between the metallurgically yes not vollflächig vcrbundenen material layers.
  • a preferred application of the production process for the production of pipes according to the invention is the production of double-layer pipes according to the invention, however, the invention is not limited thereto, also three-, four- and more multi-layer pipes according to the invention are hereby basically produced which, according to the state of the art, is at least much more difficult if not impossible at all.
  • sheets preferably metal sheets and more preferably steel sheets, as a material layer or elements of the material layer use.
  • the method of the present invention can be used as the respective inner layer and those materials - such as particularly high-strength steels - use that can not or only very difficult sweat- acid.
  • the principle of the invention remains the same: The wetting material layer acting as inner tube is already pressed into the bending roll during tube forming in a force-fitting manner into the respective material layer acting as outer tube and thus held frictionally in the respective outer tube.
  • the respectively acting as an inner tube material layer can be moved by means of force acting in the functioning as an outer tube material layer, so that a plug-in sleeve is formed, which allows Incinanderstecken of pipes, which allows a much simplified installation of the pipes on site.
  • the multilayer pipe according to the invention in particular the multilayer pipe obtained according to the present invention, is designed such that a respective inner material layer has a higher yield strength or yield strength than the respective outer material layer (see below) than this, wherein at least one material layer is preferably made of sheet metal, particularly preferably consists of sheet steel.
  • a particularly preferred embodiment of a multilayer pipe according to the invention is characterized in that the multilayer pipe is formed as a double-layer pipe, which has two layers of steel sheet, wherein the inner tube serving position steel sheet has a high to very high carbon content and thus at least not necessarily weldable at least
  • multilayer tubes can still be used.
  • double-layer tubes made of sheet steel material - are produced with high yield strength of the material of the respective inner tube at the same lower yield strength of the material of demumbleüberjetake outer tube, which is required for such uses of multilayer tubes, for which it depends on the highest possible abrasion resistance of the inner tube, as a high abrasion resistance usually also with a high hardness and this in turn goes hand in hand with a high yield strength.
  • Such multi-layer pipes which have an inner tube made of a material with a higher yield strength than a pipe arranged for this purpose, but still show no full-surface metallurgical connection of adjacent layers, can not be produced according to the prior art; they do not exist yet. On the other hand, they are made possible by the present invention. It should be pointed out that in the case of a non-pronounced yield strength - for example, in cases of increased plastic deformation - instead of the yield strength of the yield strength as the amount of stress a plastic permanent strain under a certain force occurs.
  • the method according to the invention also makes possible a much greater variety of combinations of the materials in the multilayer pipes according to the invention.
  • certain abrasion-resistant steels can not be used as the inner layer since these are due both to the high abrasion resistance i.d.R.
  • the high yield strength associated with this is not suitable for use alone (for example as a liner tube) for the tube forming process and would also have to be welded for inner tube formation, but due to their high carbon content this is not or only slightly suitable for this purpose. H. especially not necessarily weld (see above). Corresponding pipes therefore do not exist until today.
  • the method according to the invention which makes use of the frictional pressure of the respective inner tube in the respective outer tube during the production process, also enables the production of such multilayer tubes which, as inner layer, are a material which can not be welded or is not necessarily weldable - for example a steel with a high, preferably very high high carbon content - use. Also, the use of materials that can not be welded at all, such as modern plastics, which have the desired properties of a pipe inner layer, becomes possible in the first place. Tubes with such inner layers also do not exist so far.
  • the method according to the invention can also be used to produce multilayer pipes without the use of expensive and poorly deliverable plated (metallurgically bonded) metal sheets in virtually any diameter, which has hitherto not been possible in the state of the art, since here the necessary expansion is achieved by the dimensions of the expansion dies used or by a, in the case of expansion hydraulic force necessary for the uniform formation die which encloses the multilayer tube to be produced, is limited.
  • the bending roll method according to the invention allows multilayer pipes which are not subject to such predetermined limits, since the bending roll, which indeed only forms a shaping at one point of the radius of curvature of the pipe, thus does not limit the diameter of the multilayer pipe according to the invention. This makes it possible, in particular, to produce multilayer pipes without plated metal sheets which exceed the limit given by the current state of the art of approximately 610 mm (24 ”) diameter, preferably far.
  • the present invention first enables the production of multilayer tubes with partial inner layer, i. a cross-sectionally only a partial circle forming inner tube, such as in the form of a gutter insert on the pipe base, which has also not been possible according to the state of the art.
  • Fig. 9 shows a perspective view of the, later forming the outer tube, base plate 2 with stop edges 10a, 10b and, the later inner tube forming, inner plate 1 , in the still flat unprocessed state.
  • the multilayer material thus formed is formed into a multilayer pipe according to the invention with the aid of a bending roll, the respective material layer 1 serving as an inner pipe being clamped between the abutment edges 10a , 10b and thus frictionally engaged is pressed into each functioning as an outer tube material layer 2 .
  • a gap is left, which closes only in the course of the tube forming process.
  • Fig. 10 shows a cross section through a multilayer pipe 5 according to the present invention, where the base plate of the outer tube 2 has stop edges 10a , 10b and the inner tube forming inner plate 1 is clamped according to the deformation progress between these stop edges 10a, 10b, and so as a result of the bending force fit into the Outer tube 1 is pressed.
  • the gap between the edges of the overlying material layer and the stop edges 10a , 10b has previously been closed.
