Steel line pipes

Steel line pipes are designed for the specific requirements for conveying gaseous media and combustible liquids or solids. District heating tubes are particularly distinguished by a long service life and pressure resistance over long distances.  

In the area of district heating tubes, BENTELER Distribution can resort to the expertise in development and production of BENTELER Steel/Tube. Our customers have access to high quality and technologically advanced products, which we can also supply prefabricated on request.
