A piping system includes a first and a second inner tube assembled end to end and a hot fluid detector. For each inner tube, a first peripheral tube into which the inner tube is introduced and fixed. For each first peripheral tube, a second peripheral tube into which the first peripheral tube is introduced and fixed. A sleeve has a first section which surrounds the ends of the second two peripheral tubes facing one another and a second section which extends between the two ends up to the walls of the first two peripheral tubes. A pipe crosses the sleeve and opening out, on the one hand, into the space between the inner tubes and the first peripheral tubes and, on the other hand, in the vicinity of the hot fluid detector. A piping system of this kind is therefore thermally insulated and allows detection in the event of a leak.

Piping system with leak detection

A universal joint comprising a first band, a second band, and a third band. The three bands are cylindrical bands coaxial with one another with respect to a common axis. The first band and the second band are separated by a first slot, and the second band and the third band are separated by a second slot. Two connection points, which are diametrically opposed, assure the connection of the first band and of the second band. Two other connection points, which are diametrically opposed, assure the connection of the second band and of the third band. The two connection points between the first band and the second band are offset by substantially 90&#xb0; in rotation about the common axis with respect to the two connection points between the second band and the third band.

Universal joint with simplified structure

A universal joint includes a first band and a second band which are separated by a slot, are cylindrical and coaxial with one another with respect to a common axis, a first stiffener whose ends are joined to the first band, and a second stiffener whose ends are joined to the second band. A stem extends between the first stiffener and the second stiffener. A crown is around the stem. Four torsion bars exist, of which two extend between the crown and the first band and two extend between the crown and the second band.

A universal joint includes a first band and a second band which are separated by a slot, are cylindrical and coaxial with one another with respect to a common axis, and further includes a first torsion bar, whose ends are joined to the first band, and a second torsion bar whose ends are joined to the second band.
