Advantages - Why Brandenburger Liner

Thanks to the long-term modulus of elasticity of 11,180 N/mm² or 13,288 N/mm², a high mechanical strength can be ensured. This makes it possible to design the liner thinner, which saves material costs as well as makes the installation quicker and more reliable.

Components & Quality assurance

Constant improvement of the products


The main components of our pipe liner are glass and resin. To ensure fault-free function at the construction site, the other components also need to be appropriately coordinated.

 

To ensure optimal quality of our products at any time, we have had our company certified for DIN EN 9001:2015 by TÜV Hessen. Additionally we are subject to the 6-month independent inspection according to the DIBt regulations and additionally conduct quality audits at our suppliers.

Our pipe liners are offered in two different versions. For the domestic sewage range, a UP resin (unsaturated polyester, acc. to DIN 18820 group 3; type 1140), which is temperature resistant up to 50 °C with normal sewage.

The second version is a VE resin (vinyl ester, acc. to DIN 18820 group 5; type 1310), which is recommendable for industrial wastewater. The resistance against chemicals depends on their concentration and temperatures up to 70 °C can be withstood.
