Welded sleeve, or replacement of line repair methods have been used successfully for many years in the pipeline industry but can lead to other difficulties for a pipeline operator. Clock Spring`s composite sleeves have been used in over ten thousand pipeline repairs with pipe sizes ranging from 6- to 56-inches in diameter, all without costly shutdown, welding or purging. Repairs can be completed while the pipeline is fully operational and require only six inches of clearance under the pipe for wrapping the eight thicknesses of the coil. This minimizes costly digging and backfilling over long runs of pipe and necessary shoring for personnel safety. Also it provides a more cost-effective alterative to conventional pipeline repair since special handling, lifting, or installation equipment is not needed. This paper reviews the installation and performance of these sleeves.
