Maximizing cryogenic performance really comes down to how well you can maximize the regulator and create more flow. And how you can do that reliably and consistently without the hiccups of flow inconsistencies that create downtime for the customer. Here is where some regulators are miles above the others.

The evolution of the cryogenic and industrial gas industries over the last few years has led to better safety and greatly improved transportation and storage of larger amounts of liquefied gases for longer periods of time. That said, cryogenic storage tanks will eventually experience temperature fluctuations due to their surroundings, resulting in occasional temperature increases inside the tank, which causes liquid gas to evaporate back into a gas state known as “boil-off gas.” Safety relief valves handle and mitigate that pressure rise.

Hydrogen embrittlement, sometimes called “metal embrittlement,” is a common problem for hydrogen service, and one that can be prevented by choosing properly designed valves for low-temperature hydrogen service. In this blog, we explain what hydrogen embrittlement is and what can be done to prevent it.

Hydrogen, specifically green hydrogen, is growing in popularity as countries and industries look for climate-friendly energy solutions that reduce reliance on fossil fuels. As demand grows, so does the need for developing a safe, reliable infrastructure that makes that transition more feasible.

When it comes to hydrogen systems, high-quality stainless steel is the rule, not the exception. Resistant to rust, discoloration and warping, stainless steel performs exceptionally well under harsh conditions. Not only relied upon for hydrogen systems, stainless steel components are also critically important in high-purity applications like cannabis extraction and oxygen service, where high quality is a necessity, not an option.

As hydrogen continues to increase in popularity, a particular focus is finding valves and components that are tough enough to stand up to hydrogen. By affecting the electrochemical kinetics of certain metals, hydrogen can cause pitting and acceleration of the rate of inter-granular corrosion of high-strength steels, titanium alloys and aluminum alloys, which are the most vulnerable metals. Additionally, the interaction of hydrogen and stress can result in escalated stress-corrosion cracking susceptibility of steel, particularly in welded joints.
