20080277931 | CONNECTION FOR CONDUITS AND METHOD FOR MAKING IT - The invention concerns a connection between a largely rigid pipeline and a flexible conduit element by means of a steel nipple, reaching with its one end into the pipeline and with its opposite end into the flexible conduit element, wherein the flexible conduit element is secured to the nipple by means of a clamping sleeve. The basic problem, to configure a flow-favorable connection between a rigid pipeline and a flexible conduit element so that a compact tie-in of the flexible conduit element is possible without the materials being affected by the type of connection technique, is solved in that the pipeline in the segment receiving the nipple and the clamping sleeve are subjected to magnetic pulse shaping coils to reduce a cross section thereof and the pipeline and the nipple have substantially the same inner diameter. | 11-13-2008 |
