Liners

Flexible high-quality liners help you line any pipe. Boldan offers liners in numerous sizes, from 30 mm to 500 mm in diameter. Our flexible liners mean you can even line pipes that have change in diameter in the section  being lined. Our selection also includes unique two-sizes flexible liners.

Calibration Hoses

Calibration Hoses are used in open-end installations to squeeze the liner to the wall of the pipe. Also used in the manufacture of glued open-end liner and to prevent excessive swelling of the liner in free space. In Boldan's range you will find the Calibration Hoses in sizes D50 - D400. Calibration Hoses are also available in flexible and heat resistant versions.

Preliners

Preliner is installed between the old pipe and the liner in order to protect liner and resins for example from dampness and sharp edges. Preliner avoids the spreading of the dissolved 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 excessive swelling of the liner. It is recommended that Preliner is always used in the concrete pipes to prevent any damage caused by the water outside the pipe.
