Hydrogen

Fittings, screw connections, and valves play a crucial role in hydrogen applications, particularly in the fields of electrolysis, refueling stations, storage, fuel cells, and compressors. These components are essential for ensuring the safety, reliability, and efficiency of the hydrogen system. Fittings and screw connections are used in electrolysis plants to split 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 withdrawal of the stored hydrogen. In applications with liquid H2, an insulating line (for example, under vacuum) is often required around the media-carrying line. Our ZeroCon screw connection is ideal for this, as it maintains a permanent vacuum.

Hydrogen fuel cells convert hydrogen into electricity to power vehicles, buildings, and other applications. Here, precise fittings and valves are crucial for delivering hydrogen to the fuel cells and disposing of waste.

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

The selection of high-quality fittings, screw connections, and valves is crucial to prevent leaks, corrosion, and failures, which 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 compatible with hydrogen.

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

Stainless steel clamp-type wedge ring fittings (also known as clamp ring fittings or double-ring fittings) are suitable for hydrogen applications.

They are characterized by extreme gas tightness, are vibration-resistant, and the use of high-quality stainless steel (AISI 316 / AISI 316 L) guarantees material safety. They are relatively easy to install and do not require special tools.

At Schwer Fittings, the fittings are manufactured in our own European plants. The production of sensitive components, such as the clamping and wedge rings, takes place at our plant in Germany.

Compression-Fittings and twin ferrule fittings are ideal for hydrogen and gas applications.

The twin ferrule fittings are EC 79, DNV, and TA-Luft certified; the cutting ring fittings are DNV certified.
