3D Liner (3'' - 4'') 4.5mm - 328' Roll

Easy to install, transitional liner for professional use. Suitable for relining DN70 - DN110 (3'' - 4'') 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. NOTE! The air pressure used in the installation affects the elongation of the liner. Boldan 3D SN8 liners are suitable for relining inside the building, pipes in traffic areas, road construction, and other heavier loads. 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). Allows lining up to 90°, the result is almost wrinkle-free. , TECHNICAL FEATURES Material: 100 % Polyester Membrane: Polyurethane (PUR-HD) Material thickness: 4.5 mm with membrane Nip Gap: 11.0 mm Installation pressure: 0.4 - 0.7 bar / 5.8 - 10.2 psi Curing pressure: 0.3 - 0.5 bar / 4.4 - 7.3 psi Maximum pressure: 0.8 bar / 11.6 psi Epoxy consumption: approx. 1.11 kg / m , Compatible with the following epoxy resins: Boldan Oy: BDA / BD / BDA + / BX / BE / BA / BC / B1 , Package size 100 m / 328 ft , Made in Finland
