Sealing flanges is important to safety when handling hydrogen

Sealing connections is crucial

Hydrogen is emerging as a major alternative energy source due to its abundance and potential to reduce greenhouse gas emissions. However, the use of hydrogen presents significant challenges, especially in relation to the management of connections and joints in hydrogen systems. Sealing connections is a crucial aspect of ensuring the reliability, efficiency, and safety of such applications, as hydrogen is a highly permeable and flammable gas that requires robust solutions to prevent leaks of ensuring system integrity.

In this context, it is essential to adopt sealing materials and techniques that are not only compatible with hydrogen, but also resistant to variable environmental and operating conditions. Choosing the right sealing method can make the difference between a highly dependable and efficient system and one that is subject to significant risks.

Key insights

The leak tests conducted demonstrate that anaerobically cured flange sealants successfully sealed hydrogen gas on metal flanges.
The thread sealants were tested on larger fitting sizes than previous tests, providing a high level of operational flexibility at different sizes and temperatures.
The sealants evaluated in this report provide a cost-effective and reliable method of sealing flat-faced, rigid metal flanges for use with hydrogen gas.
Anaerobic sealants also provide an additional level of safety for sealing threaded connections by preventing self-loosening.
