First CarboSeal® installation with PN 25 in Austria!

Another milestone in trenchless district heating rehabilitation was reached at voestalpine's steelworks in Leoben: For the first time in Austria, our CarboSeal® system was used in a pipeline with a pressure rating of PN 25. Two DN 200 liners, each 37 meters long, were installed – a challenging project that was a complete success thanks to the excellent cooperation of everyone involved.

The voestalpine Donawitz fire department took over the water supply for the steam unit – a big thank you for their dedicated support!

The entire organization, including cleaning, flushing, and TV inspection, was handled by Quabus. The collaboration between voestalpine, the plant fire department, QUABUS, and the PPR Deutschland GmbH team worked seamlessly.

With perfect weather and a very positive atmosphere, the project was completed successfully and on schedule. A strong testament to the performance of CarboSeal® – even under the most demanding conditions.
