Steel line pipes
Steel line pipes are designed for critical applications. They can be used for the transmission of crude oil, natural gas and petroleum, as well as for water pipeline applications.
Our district heating tubes are particularly distinguished by a long service life and pressure resistance over long distances. Due to our close collaboration with BENTELER Steel/Tube, our customers have access to high quality and technologically advanced products. On request, we can also supply the district heating tubes prefabricated.
