Reliable Ball Valves and Standardised Tests for Hydrogen Applications

15 Jun 2020  |
In addition to special hydrogen ball valves and wellheads Hartmann Valves now also offers material suitability and hydrogen leak-tightness tests for challenging hydrogen (H2) applications.

Reliable shut-off valves, the right material selection as well as standardised pressure tests help users to increase the operational safety in existing and new hydrogen application areas.

Durable special Hartmann ball valves are equipped with a true metal-to-metal sealing system and are gas-tight, even at high pressures up to 690 bar. Special designs for temperatures up to 550°C are available. The Double Isolation and Bleed (DIB) option provides additional safety.

For all metallic components in direct contact with hydrogen Hartmann offers standardised material suitability tests. Within the test scope the metallic material selection is evaluated regarding its resistance against hydrogen embrittlement to make sure that it is fit for hydrogen service. Furthermore, a comprehensive pressure test with hydrogen provides assurance, that the threshold values are adhered to and fugitive emissions are minimised. Thanks to these professional tests also inventory valves of Hartmann and other manufacturers can be upgraded

Special valves, which have evolved for the demanding hydrogen medium, have been used in the petrochemical industry for many decades. With energy transition, hydrogen will be found increasingly in other fields of application – from electricity generation (such as power-to-gas), through transport (in natural gas grids or hydrogen pipelines), to processing and mobility.

The underground storage of hydrogen in salt caverns constitutes an environmentally friendly and safe solution for storing large amounts of energy to balance between power generation and demand.

Here, wellheads serve as secure interface between underground and surface.
