Easy to install, transitional liner for professional use.
Suitable for relining DN100 - DN150 (4" - 6") pipelines.
This unique material maintains the layer thickness in the larger pipe section. The calculated length reduction in the larger diameter is approx. -10 % of the length.
Boldan 3D SN4 liners are suitable for relining waste and rainwater pipes inside buildings and lightly loaded yards and green areas.
The liner is suitable for steam, hot water, or air curing following Boldan® process instructions. Maximum temperature for steam or hot water curing +65 °C / 149 °F.
The liner must be protected against radial expansion with a calibration hose (inspection hatches, manholes, beginning and end, and other free spaces).
Up to 90° bends without wrinkles.
