SLEEVES FOR FAILURE REPAIR IN RADIAL WELDS OF PIPELINES.

摘要

The present invention relates to the manufacturing of equipment and material for the maintenance of pipelines conveying hazardous materials, especially flammable compounds. More particularly, the present invention relates to the maintenance of radial welds due to failure. The competitive advantages of the present invention with respect to prior state-of-the-art structures, are characterized in that the assembly allows moisture and other foreign substances to be removed from the gap located between the repair means and the pipe to be repaired, also allowing to remove a differential expansion that would cause failures to become larger, and the pipeline force to be transferred to a repair sleeve, thereby enhancing the mechanical strength in the repair area. The invention comprises a sleeve disposed about the pipe area to be repaired and an incompressible resin member arranged between the outer pipe surface and the inner surface of the sleeve, the sleeve including a larger diameter at the longitudinal central portion thereof which gradually decreases towards the lateral ends thereby forming an aperture through which resin is injected, the sleeve also comprising a peripheral groove for receiving the weld of the pipe to be repaired.
