Our inversion drums are CE-certified, made from aluminum or stainless steel and are suitable for air, steam and water inversion installation. We will provide you with the most suitable drum for pipe renovations for apartments as well as larger municipal infrastructure renovations.

With Boldan`s drill and milling equipment, opening a lined branch sewer can also be done via the main sewer. You will always find the right equipment to successfully and quickly cut open any lined branch pipe. Cutting robots enable us to open feeder lines to pipes conveniently through the main line. Our selection includes the most powerful cutting robots equipped with turning milling arms.

Before the renovation, pipes are cleaned mechanically by grinding and washing to ensure the quality and durability of the renovation. Our selection includes high-quality stainless steel X-Chain grinding chains equipped with cemented carbide teeth.

The calibration roller ensures that the epoxy is spread evenly throughout the liner. From our selections, you will find both electronic and manual calibration rollers for all your pipe lining needs.

Our selection includes several different epoxy resin product families to guarantee that you will always find the best product for each job. We only sell tested and safe epoxy resins which are designed specifically for pipe renovation work.

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 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.

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.

We manufacture high-quality Connection Liners that fit all branch-off pipes. Thanks to 3D cutting, our Connection Liners always sit tightly and ensure the water-tightness of the branching. With flexible Connection Liners, even the most challenging branches are easily and quickly lined. Our selections includes Connection Liners for all sizes of pipes and degrees of angles. We also manufacture products according to our customer`s specifications.
