GRS Gangelberger & Riedlbauer Service GmbH

The company Gangelberger & Riedlbauer was founded in 2002 by Herbert Gangelberger and Hermann Riedlbauer as OEG. Due to the successful development of our customer base, the transformation to Gangelberger + Riedlbauer Service GmbH became necessary in 2007. As a recognised and certified specialist company, we have specialised in on-site mechanical machining and industrial leak sealing.

Since 2021, GRS Gangelberger & Riedlbauer Service GmbH has been part of the Bardenhagen Group, which is one of the leading companies in Germany with its business fields. Only a few other providers have a similarly broad range of services.

Important services at a glance

  • Leak sealing during operation: By using different, proven technologies, leaks in pipelines or fittings in pipeline networks are sealed during operation and under pressure. With our "leak sealing under pressure" service, leaks are repaired without interrupting operation.
  • Onsite machining (OSM): Onsite machining is the machining (turning, milling, drilling, grinding) of components in an installed state using mobile machining equipment.
  • Hottapping - pipe tapping under pressure: With our hottapping service, technicians from the specialist company GRS GmbH tap pipelines under pressure for necessary repairs. Hottapping is carried out during ongoing operation and saves you having to shut down the affected plant. It is also no longer necessary to drain the plant or the pipeline network at great expense in order to create an outlet or bypass. Interruptions to operation due to necessary installation work are successfully avoided, operating costs and downtimes are drastically reduced by hottapping.
  • Pipe freezing under pressure: With the "pipe freezing under pressure" process, employees of GRS GmbH freeze pipelines with nominal diameters DN 50 to DN 400 for necessary repairs.

Continuous further training of the employees is ensured in regular in-house training courses.
