Parker Hannifin is pleased to announce the successful completion of Rapid Gas Decompression (RGD) testing for advanced sealing materials in both 100% Hydrogen (H₂) and 100% Carbon Dioxide (CO₂) environments. Conducted in accordance with the ISO 23936-2 industry standard for RGD, this testing demonstrates the exceptional performance and reliability of Parker compounds under high-pressure gaseous conditions.
Importance of RGD resistance
Rapid Gas Decompression is a critical consideration for sealing materials used in applications where exposure to high-pressure gaseous environments is prevalent. RGD can lead to material failure if seals are not designed to withstand sudden changes in pressure, which can occur during operational scenarios or system failures.
Rapid Gas Decompression (RGD) resistance is essential for elastomers used in high-pressure gas applications across various industries, including Oil & Gas, Chemical Processing, Automotive, and Renewable Energy. RGD can happen during sudden drops in pressure, putting significant stress on sealing materials, which can lead to leaks and safety risks. In the oil and gas sector, for example, preventing leaks in downhole or surface equipment is crucial to protect the environment, while in aerospace, maintaining system integrity is vital for safety. Elastomers designed to resist RGD help ensure reliable sealing and compliance with safety regulations, providing peace of mind for operators and users alike.
As the world shifts towards cleaner energy sources, the importance of RGD-resistant materials grows, particularly with the increasing adoption of hydrogen in power generation and transportation applications, such as fuel cell vehicles. These materials are key to ensuring safety and durability in gas compression, storage, dispensing, and on-board fueling systems. By prioritizing RGD resistance, companies not only enhance the reliability of their products but also contribute to a more sustainable future. This commitment to safety and performance is vital as industries navigate the challenges of modern gas handling and strive to meet the demands of a changing energy landscape.
