Abstract
The present invention relates to a device for laying an expansible lining in a conduit. The device may include a patch having an initial diameter less than that of the conduit, and the patch may be configured to deform by radial expansion beyond an elastic limit to an expanded diameter such that it may contact a wall of the conduit. The device may also include an expander tool axially displaceable inside the patch, and the expander tool may be configured to cause the radial expansion of the patch to an expanded diameter. The device may also include a checking member mounted in proximity to the expander tool. A section of the checking member may be calibrated so that the checking member and the expander tool are capable of passing freely inside the patch when the patch is properly expanded, and the checking member and the expander tool are unable to pass inside the patch when the patch is improperly expanded.
