API Updates API 6D to Address Hydrogen Gas Service

The American Petroleum Institute (API) today announced the publication of Addendum 2 to API 6D, 25th Edition: Specifications for Valves. This update introduces important new provisions that address the unique challenges associated with hydrogen gas service, underscoring the industry’s ongoing commitment to safety and innovation.

 
“Updating API 6D to include Annex M for hydrogen gas service is a proactive measure that meets the evolving needs of the oil and natural gas industry,” said Anchal Liddar, API Senior Vice President of Global Industry Services. “As hydrogen becomes increasingly significant in the energy landscape, this update will ensure valve safety and performance in hydrogen applications.”

Key Features and Updates
The updated API 6D introduces several new requirements:

• Design Validation: Includes high-pressure gas and fugitive emission tests to assess valve performance.
• Material Specifications: Details requirements for metallic and non-metallic components to ensure durability in hydrogen environments.
• Supplemental Acceptance Testing: Introduces additional testing protocols, including those for high-pressure gas and fugitive emissions production tests to verify valve reliability.
• Fire-Safe Certification and Antistatic Design: Ensures that valves meet acceptable standards for safety in hydrogen environments.
• Additional Non-Destructive Examination: Provides additional checks to assess valve integrity over time.

Additionally, manufacturers can obtain a Monogram license for the production of valves in accordance with this addendum.

The release of Addendum 2 to API 6D, 25th Edition, highlights API’s commitment to protecting workers, communities, and the environment while advancing the integrity and reliability of critical pipeline infrastructure.
