voestalpine Tubulars secures expansion of the Semmering Base Tunnel with high-tech tubes

Following completion of the Semmering Base Tunnel, the new ÖBB southern line will create a completely new and, above all, rapid connection between Vienna and Graz or Klagenfurt. voestalpine Tubulars, a joint venture between the Austrian steel and technology group voestalpine and the American group NOV Grant Prideco, is providing high-strength tubes for safe tunnel driving in a highly complex geological environment. Together with the supply of high-tech rails, high-speed turnouts and the associated digital signaling technology from voestalpine Railway Systems, the voestalpine Group is thus making a further significant contribution to the implementation of this major project.

Best mechanical properties and highest quality for challenging conditions: The seamless tube specialist voestalpine Tubulars supplies and installs high-strength steel tubes with the appropriate know-how for one of the most important infrastructure projects in the heart of Europe.

The Semmering Base Tunnel is one of the most complex tunnel constructions in Europe due to the challenging geological conditions with hard, soft, dry and water-bearing layers. From 2030, it will connect Gloggnitz in Lower Austria with Mürzzuschlag in Styria over a length of 27 kilometers and enable a journey of less than two hours by train from Vienna to Graz.

Seamless tubes not only for the energy sector
The premium tubes from voestalpine Tubulars are used in a wide range of industrial sectors: in the energy industry, the commercial vehicle and automotive industries and in various applications in the construction industry. The high-tech seamless tubes are also indispensable in the alternative energy sector, such as for the storage and transportation of hydrogen.
