The pipeline or duct to be rehabilitated will first have been de-silted, cleaned and surveyed and the information gathered from which the design dimensions of the liners will have been determined.
Once manufactured, the liner material elements will be trucked to the job site, offloaded and stored in a convenient location close to the job site.
Access pits are prepared at suitable locations along the length of the pipeline to allow insertion of the Channeline sections. The Channeline segments are lowered into the pipeline and a special hydraulic trolley unit is then used to transport each liner segment along the length of the host pipe to the required location.
Each liner segments connects easily to the previously installed one by means of the socket and spigot joint, Once butted together, the joints are injected with a flexible mastic epoxy adhesive/filler.
After installation of the liner segments the annular gap between the host pipe and the Channeline segments is subsequently filled with a low viscosity, free flowing, rapid setting, and high-strength grout.
The same installation procedure applies to the Channeline SL with the exception that the Channeline SL sections are either jacked or winched in from the entry pit. The segments are connected through a gasket sealed bell and spigot joint, The Channeline CL can either be installed using the same procedure as the Channeline SL, or be manually installed.
Channeline pipeline rehabilitation liners are installed worldwide by a network of trained and approved specialist contractors, experienced and trained in confined entry.
