Brandenburger Liner BB1.0

Ideal CIPP for small diameters

The Brandenburger Liner BB1.0 marks the introduction of a new product design at Brandenburger. This UV light-curing pipe liner has been especially developed for the small nominal widths. The base material has been specifically developed in-house to cope with small nominal widths. This increases the cost-effectiveness of the installation, combined with all the benefits of the UV liner.

These advantages are:

-          Liner rapidly installed by being drawn into the sewer

-          TV inspection before curing to check the quality of the pipe liner

-          No shrinkage after curing

-          Possible to directly connect the liner and the side inlets

-          No coating on the surface - homogeneous form over the entire wall thickness

Components & Quality assurance

The main components of our pipe liner are glass and resin. To ensure fault-free function at the construction site, it must be ensured that the other components are also compatible.

To ensure optimal quality of our products at all times, we have obtained DIN EN 9001:2008 certification for our company from TÜV Rheinland. Additionally we are subject to the 6-month independent inspection according to the DIBt regulations and also conduct our own 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.

We use ECR Ultrapipe glass exclusively, which was developed together with our supplier specifically for the production of the BB2.5. The material thickness of the glass fibre composite is 0.7 mm. This effects an efficient application of the material, because the deviation to the statically necessary wall thickness lies at 0.6 mm maximum. Cost advantages for the project calculation are the result.

Our glass fibre, which is sewn onto the entire surface of each individual glass roll, forms a homogeneous surface in the pipe liner, which improves the flow properties in the sewer and ensures the durability against wear as well as cleaning in the sewer.

In meeting the requirements of the Advisory Leaflet DWA M143-3, our pipe liner is resistant against abrasion for 50 years of use in the sewer. The glass-fibre-matt bonded wear protection layer is 0.1 mm thick.

The 3-layer structure of the pipe liner includes, in addition to the GFRP web, a transparent inner foil as well as a grey UV-protective coated, external foil.

The inner foil used, with 120 ym, is a two-layered transparent foil. The basic material is PE for ensuring the integrity of the foil during calibration and a thin layer of PA which serves as a styrene barrier.

The external foil used by Brandenburger is a 220 ym thick, three-layered PE/PA/PE foil. The PA layer functions here as a styrene barrier. The foil has the special feature of a laminated PE fibre on the inner side. This provides the pipe liner with an especially good stability for installation in the sewer.

Our BB2.5 liner features an additional external protection for better protection during drawing in at no extra cost as of a diameter of DN 600. This PVC woven foil features enormous tensile strength and is applied to the liner as a second protection against mechanical damage.

In the Brandenburger Liner BB1.0, we use a special base substrate made of glass/polyester fleece. This composite material has a thickness of 1.0 mm. The use of polyester fleece increases the cost-effectiveness of the refurbishment work on pipes with small nominal diameters, since these have lower static loading requirements.

Our glass/polyster fibre forms a homogeneous surface in the pipe liner, which improves the flow properties in the sewer and ensures its durability against wear and cleaning of the sewer.

Each of our produced pipe liners is packed into an own wooden crate at no extra cost. This is adapted to the ordered pipe liner and manufactured individually for each customer in our own carpenter's shop. The wood used is adapted to the specific needs of the construction site.

The subsequent shipping of the materials to the construction site is planned by our order processing department. We cooperate with a transport specialist to make a hassle-free construction site workflow possible.
