Definitions
- the invention relates to a method for producing a Composite pipe for the conveyance of liquid or gaseous Media in a heated or cooled state, the composite pipe at least one inner tube made of plastic and one has this encasing metal tube.
- Such a manufacturing process for plastic-metal composite pipe is from DE-A1-29 23 544, DE-C1-34 32 944 and EP-A-0 127 127.
- a metal band is formed around a plastic tube, so that its extending in the longitudinal direction of the plastic tube Band edges lie together. In this condition the strip edges are welded together. Doing so provided that the inside diameter of the metal pipe is larger than the outer diameter of the plastic inner tube. The differences in diameter are partly clear Are defined. It is also described that the metal pipe after welding is reduced in diameter to create a connection between the two pipe materials. After this reduction process, the prerequisites are first created for an adhesive connection of the two pipes.
- EP-A-0127127 The method known from EP-A-0127127 is the generic term of claim 1 is based.
- the metal inlays of composite pipes are preferred thin-walled and the pipe diameter as well as the purpose adapted to the pipes.
- the free shaping of thin Metal strips to pipes is because of those that occur during molding Marginal stresses in the tape are generally known. That's the way it is extremely difficult in the endless production of thin-walled pipes for guiding the belt edges for the Welding process in the mold to ensure that an absolute optimal and constant welding result ensured can be.
- the registration is based on the task, an endless to coat extruded plastic pipe, being a Metal tape by fitting the tape edges around tight the plastic tube is shaped in the longitudinal axis and is gas-tight is welded.
- the invention provides a method for solving this problem proposed with the method steps of claim 1.
- the features of advantageous developments of the Methods according to claim 1 are each in the subclaims specified.
- the longitudinal ones Band edges of the metal band before laying the same angled around the plastic inner tube.
- the adjacent band edges are essentially radially from the inner tube when the metal band around the Inner tube is placed.
- the method presented has the basic idea that Plastic inner tube with a metal band to form and by bending the band edges a reliable To allow welding.
- the use for forming the metal band is very great allows thin metal bands.
- the metal tube shape as the tolerances that occur are also affected by the Inner tube determined.
- the non-positive shape according to the invention of the metal band around the inner tube become oxygen inclusions avoided during the subsequent longitudinal seam welding disruptive and also the adhesive connection between Adversely affect inner tube and metal sheathing.
- the invention has the advantage that on pipe calibration or Reducing devices can be dispensed with because of the Composite plastic inner tube with the metal jacket dimensioned and is welded to fit. Because the strip edge preparation according to the invention can the longitudinal seam welding of the metal pipe on the plastic inner tube without an air gap. Furthermore, a trimming operation of the tape is as general usual, not necessary, because those guaranteed according to DIN Width tolerances for fine strips are for one trouble-free manufacturing process absolutely sufficient, with what increased operational safety of the manufacturing plant becomes.
- Aluminum used because of the low specific weight is preferred Aluminum used. This also means that mechanical properties, flexibility and for the endless production so important the ability to be wound up Get pipes.
- a AC-DC method used for the welding process itself. So that's it possible, aluminum without further pretreatment (oxide layer) to weld and moreover, homogeneous and to produce mechanically resilient weld seams.
- the welding speed that can be achieved with it to see. Welding by AC / DC gives this type of production the greatest possible Security in continuous continuous operation.
- the metal tube is particularly after the longitudinal seam welding warm in the area of the weld. With the cooling of the The weld seam is shrinking. This carries to ensure that the metal tube is non-positively on the inner tube is pulled.
- the tube combination Plastic metal is heated all around.
- the adhesion promoter is activated and the bond between the two is tight superimposed pipes made of different materials takes place and is centric again starting shrinking process of the metal shell favored.
- the process of gluing the two pipes against each other is done by the positive forming favored and by theshrinking process optimized after thermal treatment.
- a composite pipe manufactured by the method according to the invention is in the drawing in different views shown.
- 1 shows a perspective view a partially broken plastic-metal-plastic composite pipe, while the figures 2 and 3 Show cross sections.
- Fig. 4 is a perspective view of the composite pipe after partial welding the formed from the upstanding band edges of the metal tube Longitudinal seam.
- the composite pipe has a plastic inner pipe 1 made of PE or XLPE material around which a metal band made of aluminum formed with angled band edges 3 to a metal tube 2 becomes.
- the adjacent radially protruding Band edges 3 are joined together by means of a welding head 4 welded.
- the band edges 3 (Fig. 2) can the height of the weld can be determined (Fig. 3).
- an outer tube 5 made of PE or XLPE material can be extruded.
