For an internal operating pressure up to 3 bar

The Berolina-LP-Liner (LP = Low Pressure) is used in wastewater pressure pipe rehabilitation. By using very resistant glass and the particularly favourable structural arrangement of the glass sheets, a maximum internal operating pressure of 3 bar is possible.

Reaching the target with low pressure

The standard Berolina-Liner was modified and used for the low-pressure range under the name Berolina-LP-Liner in order to rehabilitate pressure pipes too. This liner was installed for the first time in 2008, in the CHP plant in Reuter West in Berlin. The installation sequence differs from conventional rehabilitation methods due to the preparation and follow-up work. In wastewater pressure pipes, all sharp-edged deposits must be removed before the liner is pulled in. This is followed by pulling in a slip liner, the liner, calibration and UV light curing. The liner ends are joined onto the existing pipe by means of a flange joint. This method replaces the time-consuming replacement of pipe sections.
