Apparatus for limiting a leak in the event of a rupture in pipework
First Claim
1. A device for permitting axial expansion of a pipework and for restricting leakage in the event of rupture of a section (3) of pipework by preventing offset of the respective axes of ruptured portions of said pipework upon rupture of the pipework at said section (3), said device comprising:
- two flanges (4,
5) mounted concentrically on said pipework on respective sides of said section (3) of the pipework to be protected, each of said flanges including means for respectively fixedly securing said flanges axially on said pipework to opposite sides of said section (3), assembly means (10,
11) coupling said flanges including members (12) having axial resilience for permitting said pipework on respective sides of said section (3) to expand axially, and each flange being constituted by two half-collars (5A, 5B), assembled together and extending completely about the periphery of said pipework, whereby the portions of the pipework to respective sides of the section (3) are prevented from being thrown out of alignment in the event of rupture of the pipework at said section (3).

Abstract
A device for limiting a leak in the event of a rupture in pipework (1, 2), the device being characterized in that it comprises two flanges (4, 5) mounted on the pipework on respective sides of a section (3) of the pipework to be protected, the two flanges being assembled to each other by assembly means (10, 11) including members (12) having axial resilience leaving the duct free to expand axially, each flange including means (6, 7, 8, 9) for securing it axially on the pipework, and being itself constituted merely by two half-collars (5A, 5B) that are assembled together.
