The German steel group Salzgitter AG has signed extensive agreements with ONTRAS Gastransport GmbH for the supply of pipes for a new hydrogen pipeline, which will be a key element of Germany’s national hydrogen infrastructure.

Pipe Supply for Strategic Hydrogen Project
Under the signed contracts, Salzgitter’s subsidiaries – Mannesmann Grossrohr GmbH (MGR) and Mannesmann Line Pipe GmbH (MLP) – have committed to manufacture and supply over 108 kilometers of pipes of various diameters for the FGL 702 project. Specifically, MGR will provide 70.6 km of pipes weighing approximately 18,000 tons, while MLP will supply 38.2 km of pipes weighing nearly 6,000 tons.
The new FGL 702 pipeline will run from Wefensleben to Salzgitter and from Angersdorf to Proyslitz. This project will be an important component in the development of the country’s hydrogen network and will support the energy transition as well as the production of “green steel” at Salzgitter’s facilities.
“The integrated steelworks in Salzgitter will be transitioned to low-carbon steel production in several phases. Hydrogen is becoming an increasingly important asset for the company’s steel production transformation program – SALCOS (Salzgitter Low CO2).”
Modern Technologies and Implementation Timelines
MGR will manufacture pipes with a diameter of 813 mm, which will feature a three-layer external polyethylene coating and an internal Flowcoat epoxy lining. Specific sections of the pipeline, totaling 4.5 km, will be additionally protected with a layer of glass-reinforced plastic (GRP).
In turn, MLP will supply pipes with a diameter of 610 mm and a length of 18 meters, also equipped with a three-layer polyethylene coating and an internal Flowcoat lining, which will be applied at the production site in Hamm. Approximately 6 km of the pipeline will receive an additional layer of glass-reinforced plastic for enhanced durability.
The launch of pipe deliveries is scheduled for February 2027, allowing for the timely implementation of the project and the activation of low-carbon steel production in Germany.
