An installation securing a conduit, pipeline, piping, organ, system, machine or a similar equipment subject in the operation to high pressures due to a fluid under pressure, such as air, water, oil, steam, which circulates or in general operates in said conduit or similar equipment, comprising:
- a first part and a second part, connected between them, of the conduit or similar equipment, under pressure, secured by the installation;
- and
- a sliding cable safety device arranged between said first and said second part, connected between them, of the conduit or similar equipment under pressure,
- wherein said safety device in turn comprises:
- a flexible cable which has at least a first attachment eyelet and a second attachment eyelet formed respectively by two end portions of the flexible cable;
- at least a first sleeve and a second sleeve which close the two end portions of the flexible cable so as to form, at the two ends of the safety device, said first and second attachment eyelets;
- and
- two terminals provided at the opposite ends of the flexible cable included in the sliding cable safety device,
- wherein said first attachment eyelet and second attachment eyelet are attached respectively to such two parts, connected between them, of said conduits and similar equipment subject to high pressures, so as to retain by means of the safety device said two parts, in case of rupture, burst or in general of a fault in the connection zone of said first part and said second part of the conduit or similar equipment under pressure and secured by the installation;
- wherein the safety device is configured so that, when a rupture, a burst or in general a fault occurs in said connection zone, the flexible cable of the safety device is subject to slide in the two sleeves;
- wherein the two terminals, provided at the two opposite ends of the flexible cable, are spaced at a certain distance from the corresponding sleeves which form the two attachment eyelets at the two ends of the safety device,
- whereby, when a rupture, a breakage, a burst or in general a fault occurs in said connection zone of said two parts of the conduit or similar equipment under pressure secured by said installation, the flexible cable of the safety device slides in said first and second sleeve so as to recover and reduce said distance and consequently to push and move said terminals to stop against and cooperate into contact with said sleeves, thereby tightening the two eyelets, formed at the two ends of the safety device around said two parts, to which the same safety device is attached, of the conduit or similar equipment subject in the operation to high pressures;
- and wherein at least one of said sleeves is calibrated, that is it is designed to tighten the flexible cable of the safety device with a determined calibrated tightening force,
- whereby, in case of intervention of the safety device following a rupture, a breakage, a burst or in general a fault in the connection zone of said two parts under pressure, the flexible cable of the safety device is subject to a sliding, in said at least one of said sleeves, which is controlled by said determined calibrated tightening force, and consequently also the damping and the dissipation by friction, by means of the safety device of the energy and the stresses that develop and are released in such events of rupture, breakage, burst or fault, are controlled by said determined calibrated tightening force.
