TÜV SÜD verifies that materials and components are up to the task in these circumstances through a new form of certification. Such a certificate was given to fischer Edelstahlrohren GmbH in Achern by the testing and certification service provider.

There are many challenges in selecting the best materials for applications involving hydrogen. Complex damage mechanisms that must be considered when employing hydrogen can have a severe impact on the dependability of materials, particularly metallic materials. The laws that are in place either don’t completely address hydrogen resistance or only apply in particular circumstances.

Due to this, TÜV SÜD has created its own standard for “material resistance to pressurized hydrogen” in collaboration with component manufacturers. This standard is based on well-known international regulations like ASME B31.12, EIGA Doc 121/14, or CSA-CHMC-1 and serves as the foundation for the corresponding certification.

Dr. Thomas Gallinger, Head of Hydrogen Projects at TÜV SÜD Industrie Service GmbH, states that “with our standard, we enable trustworthy claims on the hydrogen resistance of materials and components.” Simon Schlei, Material Expert – H2 Readiness at TÜV SÜD Industrie Service, adds, “Through the structured assessment process and yearly monitoring audits in the production facilities, we generate the required confidence in a hydrogen market that is evolving incredibly quickly.

The longitudinally welded stainless steel tubes from Fischer satisfy the criteria for high-pressure applications with hydrogen, according to the TÜV SÜD certification. It contains longitudinally welded stainless steel tubes with diameters ranging from 5 mm to 205 mm composed of alloys 1.4401, 1.4404, and 1.4435. The fischer group, which includes fischer Edelstahlrohre GmbH, prides itself on being the top producer of premium stainless steel tubes and components worldwide as well as a pioneer in the development of longitudinally seam laser-welded tubes.
