  "textContent": "A gas turbine fuel feeding system (1) including at least one flexible conduit (4) connecting a fuel manifold (5) with a burner (2); wherein the flexible conduit includes a first piping with multiple metal walls (10) including at least one bellows sleeve (11) and a second piping (12) radially external to and spaced apart from, the first piping and defined by a flexible sleeve (14) delimited by a smooth outer lateral wall (15) and made of a fire-retardant silicone material, and by a pair of stiff metal tubular hubs (17) fixed onto respective smooth end stretches of the first piping and on which opposite ends (19, 20) of the flexible sleeve are fitted, in a substantially fluid-tight manner but not gas sealed-wise; at least one of the hubs being laterally provided with a nozzle (22) which connects an empty annular chamber (13) defined between the first and second piping with a sensor (21), so as to enable the sensor to detect fuel leaks from the first piping (10).",
