20110101686 | COUPLING CONSTRUCTION FOR HIGH-PRESSURE PIPE - A coupling construction includes a coupling ( | 05-05-2011 |
20100200600 | BOX-SHAPED DEVICE FOR HOLDING WATER, SUCH AS A RAINWATER BOX, AND METHOD FOR USING THE SAME - A box-shaped device for holding water, such as a rainwater box, comprising at least four partially open side walls and a panel extending between the side walls and having a rectangular shape, the width of which is half the length. The panel is provided with an inspection passage which is positioned centrally in one of the two square panel halves of the panel defined by the rectangular shape, so that whenever the rainwater boxes are stacked, a vertical passage is always provided for passing through, for example, an inspection camera. | 08-12-2010 |
20090097910 | COUPLING CONSTRUCTION FOR HIGH-PRESSURE PIPE - A coupling construction includes a coupling element and at least one high-pressure pipe, the high-pressure pipe including an external sheathing layer, a reinforcement layer and an internal lining. The coupling includes an internal welding sleeve, the external surface of which bears a helically wound heating element, as well as a force transfer element that acts cooperatively with the reinforcement layer. The heating element includes a heating wire and a shell encompassing the heating wire. The welding sleeve and the sheathing layer are fused by material originating from the welding sleeve, the sheathing layer and from the shell encompassing the heating wire. A welding sleeve for use in the coupling construction, as well as a method for producing a coupling construction are disclosed. | 04-16-2009 |
20090091128 | Coupling construction for a pipe - The present invention relates to a connecting construction between a pipe and a coupling, which pipe comprises an internal lining and a fibre reinforcement layer surrounding the lining. The coupling has a coupling piece having an external clamping surface, a sleeve which surrounds the coupling piece and has an internal clamping surface which is shaped in accordance with the external clamping surface of the coupling piece, and also a coupling end interacting with the coupling piece. The fibre reinforcement layer is secured between the coupling piece and the sleeve. The sleeve has a mount which is remote from the coupling end and the internal support surface of which extends so as to widen in the direction away from the coupling end. | 04-09-2009 |
20090085351 | CONNECTING STRUCTURE COMPRISING A HIGH-PRESSURE PIPELINE AND CUOPLING - This invention relates to a connecting structure comprising a high-pressure line having a load-bearing shell and a sealing inner cladding, as well as a coupling, which coupling comprises a flange section having a ring part and a flange which extends radially outwards with respect to the ring part, a connecting element by which the loadbearing shell of a pipe is connected to the flange section, as well as a sealing element which the inner cladding of the high-pressure line is connected to the flange section, which sealing element end in the free end of the flange section which is turned away from the high-pressure line. The sealing element comprises a sealing sleeve which is situated between the inner cladding of the pipe and the ring part of the flange section. | 04-02-2009 |
20090085346 | Connecting structure for a pipe - The present invention relates to a connecting structure between a pipe and a coupling. The pipe has an inner lining and a fibre-reinforced layer surrounding the lining. The coupling has a coupling piece having an outer wedge-shaped surface, a sleeve surrounding the coupling piece, the inner surface of which sleeve is formed to match the outer wedge-shaped surface of the coupling piece, as well as a coupling end which interacts with the coupling piece. The fibre-reinforced layer is accommodated between the coupling piece and the sleeve and is clamped inbetween. The outer surface of the coupling piece has at least two portions with different wedge angles and the inner surface of the sleeve has two correspondingly formed portions with different wedge angles. | 04-02-2009 |
20080217913 | Method and apparatus for manufacturing a pipe from pipe segments - A method for assembling a corrugated double-walled pipe section from pipe segments, having the steps of providing an inner wall segment which is curved in circumferential direction and straight in longitudinal direction, providing an outer wall segment which is curved in circumferential direction and corrugated in longitudinal direction, connecting the inner wall segment to the concave side of said corrugated outer wall segment, providing a longitudinal profile at the longitudinally extending edges of the wall segment so as to provide a pipe segment, and connecting the adjoining longitudinal profiles of at least two of the pipe segments to each other. | 09-11-2008 |
