Calibration Hoses are used in open-end installations to squeeze the liner to the wall of the pipe. Also used in the glued open-end liner manufacture and to prevent excessive swelling of the liner in free space.
In Boldan's range, you will find the Calibration Hoses in sizes DN50 – DN300 (2”- 12”).
Calibration Hoses are also available in flexible, transparent, and heat resistant versions.

Preliner is installed between the old pipe and the liner to protect liner and resins, such as dampness and sharp edges.
Preliner avoids the spreading of the uncured resin and other substances from the liner to the area surrounding the pipe.
In case the pipe under renovation has been badly damaged, preliner can also be used as formwork for the liner.
Preliner is also used in the free space (between the inversion drum and the drainage point) to prevent the liner's excessive swelling.
It is recommended that Preliner is always used in the concrete pipes to prevent any damage caused by the water outside the pipe.
