|Savay repair sleeve are designed to reinforce non-leaking, weakened, dented or damaged pipelines. They must fit snugly around the pipe when used for reinforcement applications. Gaps between the pipe and the sleeve, often caused by dents in the pipe, should be filled with a hard-setting grout. The sleeve must be butt welded longitudinally but it is not necessary to seal-weld the circumferential ends. The line can remain on-stream. Moisture should be prevented from entering the ends of the sleeve.|
|When used for pressure containment, the Repair sleeve must be fully seal welded to the pipeline in addition to the longitudinal weld. The line may also remain on-stream but the pressure must be a safe level. Savay Repair sleeve are fabricated in different lengths up to 3 meters . Back-up strips for the longitudinal butt welds are furnished with all sleeves. Savay Repair sleeve conform to ASME B31.4 and B31.8 , Individual company codes and safety practices should be observed. Savay repair sleeve are available fr0m 4″ – 56 ” pipelines.
