Definitions
- forces to contribute to these movements, or to initiate these movements, which are impressed on the outside of the installation or produced by other components of the installation and thus contribute to vibrating the pipes.
- Due to the movements not only damage to the piping itself may result, but it may, for example. Build up resonant vibrations, which can lead to major damage to the entire system. In the operation of gas turbines, it comes, for example, to such vibration movements in the pipelines of the external
- the oscillation movements can here about the welds on pipes, such as welding seams ⁇ between elbows and the burner flange damage. If there is a failure of the welds, is ⁇ with the shutdown of the entire gas turbine required, which has high downtime costs result.
- a damping material is, for example, is provided, which leads to a displacement of the vibration frequencies occurring ⁇ bung and an advantageous superposition or coupling of the movements of individual pipes. Due to the damping by means of the damping element also unwanted movements, in particular resonances can be significantly mitigated because vibration energy can be selectively converted into other forms of energy.
- damping elements silicone materials are used approximately in fuel piping of a gas turbine, which are temperature resistant up to a temperature of about 325 ° C. However, since the pipelines in question obligations sometimes reach this temperature range operation of a gas turbine, and even exceed, the risk of failure of the Sili ⁇ konmaterials.
- the connection clamp to enable a sufficient attenuation of BEWE ⁇ conditions of the pipes so that the pipes can be safely used.
- connection clamp according to claim 1 and by a pipe system according to claim 6, a fuel pipe system according to claim 10 and a gas turbine according to claim 11.

- a fuel pipe system of a gas turbine plant comprising at least a first pipeline for conveying fuel and a second pipeline for conveying fuel, which are both connected by means of a connection clamp as described above and below.
- the objects on which the invention is based are achieved by a gas turbine comprising such a fuel tube system.
- the metal wire mat typically consists of a tangle of individual twisted metal wires, with the metal wire mat giving rise to a friction of individual wires in the composite with appropriate application of force.
- the tangle can also be replaced by a textile structure of any type, as far as this causes a corresponding damping by friction of individual wires when subjected to force. This friction leads to an energetic loss, which converts mechanical energy into heat energy.
- the metal wire mat is suitable for carrying out such an energy conversion when subjected to force, even at high temperatures.
- connection clamp pipes excited into vibrational motions as with pressure fluctuations of the equipment in the pipes these movements can gen are attenuated by introduction of a vibration force in the metal ⁇ wire mat. Since the metal wire mat is thermally stable even at high temperatures, such a vibration damping can be achieved even at high temperatures, especially at temperatures of about 325 ° C.
- Piping a mechanical damping can be done.

- the first clamp arm is designed to run more than half of the circumference of the ers ⁇ th pipe and / or the second clamp arm is formed to more than half of the circumference to run the second pipe. Bleeding in the circumferential direction in this case requires a suitable simulation of the peripheral surface of the pipes, so that the pipes can be practically held in the clamp arm, without requiring further devices. Due to the course of more than half of the circumference of the respective pipe, this can be held in the respective clamp arm, without slipping out of the holder in the absence of a mechanical force. Consequently, there is an effective support mechanism.
- the first clamp arm in the area a Schellenarmendes with the second clamp arm is also connected in the region of a Schellenarmendes, the two other Schellenarmenden the two clamp arms are present unconnected.
- the Schellenarmenden here refer to the ends of the clamp arms in the longitudinal direction ⁇ direction of a material course of these.
- Kings ⁇ NEN the two associated clamp arms also have a portion which extends substantially parallel to the surface of the damping element in a linked form so that the power transmission takes place during the operation on a large ⁇ ßere surface of the damping element.
- the two unconnected Schellenarmenden each hold a pipe.
- the Schellenarmendes with the second clamp arm is also connected in Be ⁇ rich a Schellenarmendes, the two other Schellenarmenden the two clamp arms can be brought together in a releasable hook connection.

- the hook connection can furthermore be designed in such a way that the two hooked clamp arm ends have opposing beadings which engage in one another after being hooked, and thus can fix the two clamp arm ends together.
- the additional hook connection to the respectively associated clamp arm ends provide an additional attachment opportunity by means of which the pipelines further improved in ⁇ interconnected can be. Due to the solubility of the HakMIS this can be solved relatively quickly, if necessary, so that, for example, an exchange of the connection clamp, if necessary ⁇ easily, can be done easily.
- the first Schellenarm may also be ver ⁇ connected in the region of Schellenarmendes with the second Schellenarm in the region of Schellenarmendes, with the other two clip arm ends of the two clamp arms are also connected damped each other, and as a damping element at least one metal wire ⁇ mat, in particular, a further metal wire mat is provided.
- a mutually damped connection of the clamp arms ⁇ can ensure an improved damping effect compared to an embodiment in which only one of the Schellenarmenden is provided only with a damping.
- the first Schellenarm in the region of a Schellenarmendes with the second Schellenarm is in the range of one Schellenarmendes such ver ⁇ prevented that the two clamp arms, at least range ⁇ be present indirectly connected via the damping element.
- the two bracket arms are therefore always take at BEWE ⁇ account the respective pipelines, the kinetic energy into the damping element directly where the mechanical damping can take place.
- the two connected Schellenarmenden have a recess through which a retaining pin for connecting both runs.

- the retaining pin on a Schellenarmende be dismissed firmly so that it must have no corresponding recess.
- the damping element may also have a hole through which extends the retaining pin. It can accordingly be granted ⁇ ensure that the damping element can not fall out of the United ⁇ connection clamp inadvertently and the United ⁇ connection clamp as a result, can perform only an inadequate or no attenuation.
- the retaining pin may be formed as a threaded pin, which is braced with the two Schellen lenarmenden or can be clamped.
- a bracing can be carried out approximately so that the threaded pin ends are screwed with one nut, until the two Schellenarmenden present under tension.
- the threaded pin thus allows a particularly simple, ponderek ⁇ ge and easy to maintain embodiment of the retaining pin.
- the retaining pin is designed as a screw. Such may be loose through the recesses of the two
