Areas of application for fittings, screw connections and valves in the respective industries

Future with hydrogen and new energies

In the future, hydrogen will play a major role in the conversion of our energy supply. As a storage medium for ecological electricity and for mobility with fuel cell drives. When hydrogen is produced by electrolysis, water is separated into hydrogen and oxygen using regeneratively generated electricity. In a chemical process, the hydrogen reacts with oxygen. The energy stored in the hydrogen is released as electricity, which then drives an electric motor. → More Info

Our fittings for your hydrogen applications

Clamping wedge ring and cutting ring screw connections are ideal for hydrogen applications as well as for gas applications. The wedge ring fittings are EC 79, DNV GL and TA-Luft certified, the cutting ring fittings according to DNV. The fittings are produced in our own European factories. Sensitive components, such as the clamping and wedge rings, are manufactured in the factory in Germany.

Example applications

Hydrogen

Fittings, unions and valves play a crucial role in hydrogen applications, especially in the areas of electrolysis, refuelling stations, storage, fuel cells and compressors. These components are crucial to ensure the safety, reliability and efficiency of the hydrogen system.

Fittings and unions are used in electrolysis systems to separate water into hydrogen and oxygen. They ensure the safe supply of water and electrolyte solutions to the electrolysis cells.

Hydrogen can be stored in various forms, including gaseous, liquid and in metal hydrides. Fittings and valves ensure reliable sealing and removal of the stored hydrogen. For applications with liquid H2, an insulating line (for example under vacuum) is often required around the media-carrying line. Our ZeroCon fitting is suitable here, as the vacuum can be maintained permanently.

Hydrogen fuel cells convert hydrogen into electricity to power vehicles, buildings and other applications. Here, precise fittings and valves are critical to deliver hydrogen to the fuel cells and dispose of waste.

In hydrogen production and distribution, compressors are used to pressurise the hydrogen to the required pressure levels. Fittings and unions in conjunction with valves ensure the safe and efficient control of hydrogen flow.

The selection of high quality fittings, unions and valves is critical to avoid leaks, corrosion and failures that can have serious consequences in hydrogen applications. These components should meet the high requirements for pressure and temperature resistance and be made of materials that are hydrogen compatible.

Overall, fittings, unions and valves contribute significantly to the safety and efficiency of hydrogen applications and play a key role in the realisation of a sustainable hydrogen economy.
