Primus Line® is a trenchless rehabilitation of pressure pipes. That means: No more construction pits that are hundreds of feet or several miles long.
Two pits or existing chambers are absolutely sufficient for the rehabilitation of pressure pipelines. Learn here how a trenchless rehabilitation works with Primus Line®.
Small construction pits or existing chambers: That is all the space necessary for the installation of Primus Line®. Only two are required for every rehabilitation section. If necessary – junctions for example – additional pits are possible.
Rope winches are placed at the start and end pit for further work steps.
Inspection of the host pipe
Tuberculation is common in old pipelines. A clear picture of the condition of the rehabilitation section is very important for a successful installation of Primus Line®.
Visual inspection systems with high-resolution cameras and a large range of motion provide detailed recordings of the inside of the pipe, which are essential for efficient and productive pipe cleaning. They also pull through a pilot rope for the winches placed at start and end pit.
Assembly of the R-Connector
The R-Connectors by Primus Line consist of a core and a bushing.
With the R-Connectors the core is first fitted into the bushing with an anti-friction agent. The bushing has a malleable steel jacket inside that is pushed onto the liner and into an indentation on the core by a two-component resin. The result is a pull-proof unit of liner and connector.
A leak-free pull-proof connection with the host pipe can be established with a flange or welding solution.
