Definitions

  • band irons are wrapped around a core pipe and, inter alia, means are introduced between the individual layers of the wrapping during winding, with the aid of which the metal strip layers are welded or soldered to one another can be, whereby the pipe is to be sealed.
  • silicone oil is usually used as a lubricant.
  • synthetic resins are particularly suitable because of the above-mentioned requirements with regard to tightness, food safety and chemical resistance. However, these have the property that they only adhere to absolutely clean material. It is therefore essential that the surfaces of the tube which are inevitably soiled for the reasons mentioned are thoroughly cleaned after winding. However, only the tubes can be cleaned after winding, so that this results in an expensive and time-consuming process of sandblasting.
  • the advantage of such a method is that light, dense and surface-coated tubes, which are wound from metal strips, can be produced in a single operation. With this method, the strips can be continuously sandblasted in a simple manner before winding, so that the expensive and time-consuming process of sandblasting on the tube is eliminated and a drastic reduction in production costs and an enormously increased output is achieved.
  • heated metal strips which are already pre-bent by means of bending rollers, are wound in an abutting manner and offset against one another in multiple layers.
  • bending rollers they ideally have already obtained the degree of curvature that corresponds to the desired curvature of the pipe.
  • the inner layer of metal strip and the outer layer of metal strip coherent synthetic resin layer sprayed.
  • the inside surface of the pipe is created, it is also finished with a synthetic resin view.
  • the intermediate synthetic resin layer is intended to bond the metal strip layers to one another, but the required molecular crosslinking of the synthetic resin is an endothermic process, heat is already applied at this point in the process for a first activation of the synthetic resin. Only then is the outer surface of the tube sprayed with a synthetic resin, and the tube, which is now completely surface-finished, is then immediately subjected to a final curing of all synthetic resin layers.
  • the metal strips are preferably wound into a cylindrical outer shape which is both rotatably supported and is movable in the axial direction. When the metal strips are wrapped, they then do not move relative to the outer shape. Rather, the metal strips are wound further and further into the outer form by a rotational movement and simultaneous movement of the outer form in the axial direction. Thus, since the pipe does not have to be moved relative to the shape, lubricants such as silicone oil, which would contaminate the surface of the pipe, are unnecessary. This eliminates the need to clean the pipe.
  • a synthetic resin coating powder usually a thermoset, is particularly suitable.
  • the outer mold segments are designed as permanent magnets.
  • the spray device for the coating powder for spraying the synthetic resin intermediate layer between the metal strips to be wound is expediently located directly at the front opening of the outer mold, as is the spray device with which the inner surface of the wound tube is coated. Since the spraying of the outer surface of the tube is carried out immediately after leaving the outer mold, it is expedient to mount the spray device provided for this purpose directly on the outlet opening of the outer mold. After a certain networking. and calming section, the spirally offset metal strips are firmly and tightly connected. Pipes which are produced by the method mentioned and with the device described, however, do not only show the advantages already mentioned. In this way, completely identical pipe outer diameters are obtained. This is extremely important for a good seal when laying the finished pipes.
  • a cross section through an embodiment of the invention is shown schematically.
  • Rollers 4 are mounted in a rectangular housing 1 at the points of contact of the rectangular housing 1 with the outer wall 3 of the cylindrical outer shape 2.
  • the cylindrical outer shape 2 consists of four equal-sized sectors 5, with connectors 6 are connected to each other in such a way that the distances between the sectors are the same.
  • the gaps between the sectors 5 are filled by four endless belts 7, which are arranged so that the edges 8 of an endless belt 7 are in contact with the adjacent edges of two other endless belts 7. In this way, the concave end faces 9 of the endless belts 7, which point towards the center of the outer shape, form a cylindrical hollow shape.
  • the pins 14 and 14 'located on the inside of the connecting sleeve 15 are inserted into two opposing milling openings 13 and 13', and brought into their end position by rotating the connecting sleeve 15 with the function of a bayonet catch.
  • This new and inventive method of connecting two pipe ends to one another when laying the pipes ensures that even at the seams of the pipes produced with the device according to the invention, their favorable properties, namely chemical resistance and tightness, are not lost. This is especially not the case because the spraying of the outer surface of the finished tube only takes place after the bayonet catch has been milled, so that the cut edges are also surface-coated.
  • the connecting sleeve can also be surface-coated in a separate operation.
