As the energy landscape continues to evolve, hydrogen is becoming increasingly relevant in our energy matrix. However, the transition is not simply plug-and-play; in fact, hydrogen gas service presents unique challenges that require updated infrastructure and standards. Recognizing this, API has taken proactive steps with the publication of API 6D 25th Edition Appendix 2: Specification for Valves. This update introduces new requirements designed to improve the safety and performance of valves used in hydrogen gas applications.
The inclusion of Annex M (the Appendix language) in API 6D demonstrates our industry’s commitment to innovation and safety. As the role of hydrogen grows, it is imperative that we provide an infrastructure capable of safely and reliably handling this alternative fuel. The updates to API 6D ensure that valve design, materials and testing protocols are prepared to meet the unique demands of hydrogen environments.
Some of the key enhancements in this update include rigorous design validation testing, such as high-pressure gas and fugitive emissions evaluations to assess valve performance, along with material specifications that ensure durability in hydrogen service. In addition, the standard introduces enhanced nondestructive examination protocols to assess valve integrity over time and additional test protocols to verify reliability. Together, these and other updates provide reliable and safe API 6D-compliant valves for hydrogen applications.
This updated standard is also immediately eligible for the API Monogram Program, allowing licensed manufacturers to apply the API Monogram mark to products that meet the new requirements. This mark is a testament to the quality and reliability of these products, giving users peace of mind by ensuring that they meet our rigorous specifications and standards.
The API 6D update furthers our mission to protect workers, communities and the environment while strengthening the integrity and reliability of critical pipeline infrastructure. For more information, please visit the API Web Store.
