  • the invention relates to a device according to the preamble of claim 1.
  • Pipe / hose leaks especially those in the deep sea, are to this day only conditionally controllable and always a technical challenge. This is illustrated by the example of the oil spill in the Gulf of Mexico, 20.04.2010.
  • the object of the invention is to enable a quick, low-risk sealing of leaks, in particular those such as those mentioned above.
  • the new technology is intended to connect pipes, hoses, profiles or cables with each other and with connection points.
  • the technique is essentially based on a mechanical / hydraulic closure mediated by a so-called press / holding tool according to the invention.
  • the hydraulic system generates a large contact pressure for the press / holding tool, so that even under high pressure escaping liquids, substances or gases can be pushed back and the leak can be closed.
  • the strong contact pressure offers a very good resistance to withdrawing forces acting on the pressing / holding tool.
  • the borehole can continue to be used; a Zubeton Schlieren deleted.
  • the remote-controlled version should be used.
  • Security requirements e.g. are necessary for welding, omitted according to the invention.
  • press-holding tools are characterized by a combination of a holding function and a pressing function.
  • the holding function may, for example, hold the device in place. It may also hold and support the article to be pressed (e.g., the inner liner 36a and b) and / or the article to be pressed (e.g., the leak tube)

  • a holding function such as a clamp or clamp.
  • the holding function can also serve as an abutment for the pressing function.
  • the compression is used to actually seal the leakage or the connection between the Pipes, hoses, profiles, cables or joints. Either a closure is pressed over the leak or, if necessary, after preparation of the leak tube
  • Closure device / valve device Attachment device tightly attached to the leakage tube by pressing.

  • the part to be pressed is usually integrated in the press-holding pliers and possibly interchangeable.
  • the part to be pressed must be mounted on the object to be pressed and then comes in contact only with the pressing tongs for the moment of pressing.
  • the holding function and the pressing function can be performed at the same time by a pressing / holding tool or distributed to different sub-tools or more
  • the pressed parts are permanently pressed and should also be kept permanently close to the pressed part. Since the pressing tool is removed after the pressing, the compressed part must withstand the forces, in particular the pressure forces, alone. For such a part to be compressed at all, it must be made of a resilient material. In addition, it should be stable and provide sufficient resistance against peeling forces.
  • an optimum flexible compressible fitting adapted to the sealing properties may e.g. be used in the form of a cuff or leak cover, it must not be taken to sufficient stability or a permanent independent stop after pressing.
  • the hold can be taken in a variant only by the press-holding tool.
  • the pressing function of the device according to the invention brings in this variant, the cover only in an ideal contact with the pressed part.
  • the pressing function by mechanical force causes a largely permanent deformation of the pressed article.
  • the press function can result in a lasting hold on the pressed part. This is supported by the holding forceps or parts thereof.

If parts of the press-holding tools are left after being pressed, they may e.g. held by a locking mechanism in the pressing state. Alternatively, these parts can also be connected to the pressed object subsequently
  • the conventional pressing tools can only be used if the pipe connection is pressure-free.
  • the sleeves must then be pushed separately over the leak tube before pressing. Only then can such a pair of pliers be used.
  • a pressure-free position is not necessary.
  • the parts to be pressed can be part of the press-holding tool and thus be mounted in one operation.
  • the conventional technique further assumes that the workpiece to be pressed is flexible, so that it can be deformed at all and thus pressed. Furthermore, this must be too pressing part to be designed less stable than the pressed part, so that in the pressing process, the pressed part is not damaged. For this reason, the pressing technique is used only in pipes of relatively soft material such as copper or relatively soft, compliant plastic. This sets its limits to the possible maximum pressure loads of such closure systems or pipe connections. For high pressure loads, this technique is not designed.
