RELINING
To maintain the alignment of the liner
Avoid excessive swelling of the liner in the stretch of the inversion drum and the coupling point of the pipe
Liner installation from a single access point (Relining Open End)
Liner protection in vapor curing
The preliner protects the liner during the steam curing steps
For protection of the liner during inversion
During the compression phase of the impregnated sock against the damaged wall of the pipe, the Liner is not damaged as it is protected by the calibrator.
If portions of piping are missing, the calibrator is needed as a base for the liner, preventing excessive swelling.
To stop resin leakage
If the host tube is damaged, the calibrator prevents the resin from escaping outside the existing pipe
Avoid washing the resin
In case of groundwater deposit or water infiltration, the preliner avoids the washing of the resin during the polymerization phases.
Installation between impregnated Liner and host pipe
It is installed in the pipeline by pulling or inverting it and is positioned between the pipeline to be restored and the filled Liner.
In this way, during the compression phase of the filled liner against the wall, the liner will not be damaged and therefore it will be possible to proceed with the polymerization process.
Installation between the filled Liner and the inner pipe
The impregnated liner is inserted inside the calibrator. After the inversion phase, the calibrator is inside the liner and allows the latter to be protected during the heating phase
Sealing the calibrator to the end portion of the liner
The calibrator is sealed at the end of the liner creating the so-called Open end
