As of November 2017, Tiroler Rohre GmbH (TRM) was able to implement an interesting water pipeline project in northern Burgenland. The Water Supply Association Northern Burgenland commissioned PORR Bau GmbH with the civil engineering work, which in turn made use of TRM's proven pipe systems. The project envisaged the transfer of the existing pipelines in the ÖBB crossing area of the B50 federal highway. This was necessary due to the planned rebuilding of a road bridge in this area. A renovation was necessary because of the pipeline age and the risk assessment of the PIREM study of the TU Graz. Another aspect that spoke for the relocation was a simplified maintenance of the pipes in the future.
To cover the drinking water requirement, ductile iron pipes with a diameter of DN 300 were chosen. On the inside, these pipes are provided with cement mortar lining and on the outside with zinc coating including top coating. The sustainability of the investment is ensured by the well-tried cement mortar lining, as well as the full galvanizing and top coating of the delivered material. A total of about 530m of pipe was laid with the restrained VRS®-T socket joint and 240m pipe with conventional TYTON socket joint.
Safe water supply.
