In cooperation with Salzgitter Mannesmann Forschung, which has a dedicated laboratory for hydrogen research and testing projects, we have deepened our understanding of the material requirements of steel being exposed to hydrogen.

Highly specialized adaptation

Due to intensive research and targeted adjustment of the steels, our pipes have achieved material properties that make them highly suitable for transporting gaseous hydrogen in pipeline infrastructure. Tests with slow strain rates, fatigue tests, and lifespan calculations under hydrogen atmosphere at elevated pressure have shown excellent results for various applications. Mannesmann H2ready® steel pipes are therefore ideal for the transport and storage of hydrogen in pipelines. Numerous research projects are still ongoing to answer additional questions and to find solutions for the most challenging conditions.

Flexible pipeline design

To achieve greater freedom in pipeline design, we offer grades up to X70 (according to API 5L) or L485, going beyond the recommendations of the EIGA guidelines. Suitability for hydrogen atmospheres (e.g., 100 bar, room temperature, 100% pure gaseous H₂) is demonstrated upon request in a comparative test for the order. This allows for pipeline routes that were previously economically unfeasible to be realized, even in particularly demanding environmental conditions worldwide.
