ABSTRACT:
The device contains a tension chain with link plates (10) and thrust pieces (7) which are joined to one another via joints (9). Each thrust piece (7) has two flanks (5, 6) for abutting flanges (1, 2) of the pipe connection. The first of flanks (5) is tilted to plane (E1) which is perpendicular to the axes of joints (9) at a first angle. Second flank (6) with this angle forms a second smaller angle. The second angle can be equal to zero. Furthermore, the device contains tensioning device (21) for drawing two adjacent joints (9) against one another. Tensioning device (21) is arranged such that tensile forces (A) exerted by it run on the side of plane (E1) which faces away from second flank (6). Plane (E1) is perpendicular to the axes of joints (9) and passes though edge (B) of first flank (5) which is nearer second flank (6). The device is suitable for flanges (1, 2) which are differently conical or of which one (2) can also be flat externally.
