Mannesmann has received a large order from the Salzgitter Group for hydrogen
The German company ONTRAS Gastransport GmbH, headquartered in Leipzig, has signed major pipe supply contracts with two pipeline companies of the Salzgitter Group.
According to MannesmannGrossrohr GmbH (MGR) will supply 70.6 km of pipes (about 18,000 tons), while Mannesmann Line Pipe GmbH (MLP) will supply 38.2 km of pipes (about 6,000 tons).
These pipes will be used for the new FGL 702 hydrogen pipeline project, extending from Wefensleben to Salzgitter and from Angersdorf to Preislitz.
This project represents a key building block for the hydrogen backbone network and the transition to energy, forming the basis for the production of "green steel" in Salzgitter.
The Salzgitter steel mill is gradually transitioning to low-CO2 steel production as part of the SALCOS® (Salzgitter Low CO2 Steelmaking) transformation program.
Hydrogen is becoming an increasingly important resource for the production of "green steel".
Andreas Betzler, CEO of the pipeline companies of the Salzgitter Group, stated: "We are proud that hydrogen for SALCOS® will flow through our pipes and that we are part of this important project. Salzgitter is not only a major consumer of hydrogen, but also contributes to the production of hydrogen and its delivery to customers along with our steel products."
The 813 mm diameter pipes supplied by MGR will have a three-layer polyethylene coating on the outside and a Flowcoat epoxy coating.according to the interior.
About 4.5 km of the pipeline will receive an additional fiberglass (fiberglass) coating applied by TDC specialists in Neubrandenburg.
Each 18-meter-long pipe weighs about 4.5 tons and will be delivered by truck from February 2027 to warehouses located an average of 37 km from the pipe plant.
The 610 mm diameter pipes provided by MLP were prepared at the Hamm plant with both a three-layer polyethylene outer coating and a Flowcoat inner coating.
These coatings are designed to reduce friction losses during gas movement.
Approximately 6 km of the pipeline will also include a fiberglass component applied by TDC, which will further enhance the pipeline's durability.
The FGL 702 project, which is part of the IPCEI Green Octopus Central Germany (GO) initiative, aims to strengthen Germany's hydrogen infrastructure and support the energy transition.
