Repurposing Legacy Pipeline Ball Valves for Hydrogen Service – A Practical Engineering As sessment
\n \nThe UK's transition to hydrogen presents significant o pportunities to decarbonise the gas transmission n etwork\, but also raises important questions regar ding the suitability of existing infrastructure. W hilst considerable attention has focused on pipeli nes\, comparatively little has been published on t he hydrogen readiness of large-bore transmission v alves\, despite their critical role in network saf ety\, integrity and operational reliability.
\n \n\n \n
This presentation explores the UK's first comprehensiv e end-to-end hydrogen readiness assessment of a 36 -inch Class 600 three-piece ball valve removed fro m the National Transmission System after more than 30 years of service. The project investigated whe ther legacy valves can be safely refurbished and r epurposed for hydrogen service\, offering a practi cal alternative to wholesale asset replacement.
\n \nThe presentatio n covers the complete engineering assessment proce ss\, including detailed strip-down and inspection\ , material identification\, elastomer characterisa tion\, design modifications\, refurbishment\, high -pressure gas testing and fugitive emissions testi ng. It also discusses how current industry guidanc e\, including API 6D Annex M and ASME B31.12\, was applied to develop a structured assessment and qu alification methodology.
\ n \nIn addition to the technical aspects\, the session considers the wider commercial and en vironmental implications of asset repurposing. Com parative cost and embodied carbon assessments demo nstrate the potential benefits of extending the li fe of existing infrastructure\, reducing project c osts\, shortening delivery times\, supporting UK s upply chains and lowering the overall carbon footp rint of hydrogen conversion programmes.

Delegates will gain practical insights into hydrogen-relate d degradation mechanisms\, sealing technologies\, qualification requirements\, testing protocols and refurbishment criteria. The presentation provides an evidence-based approach to assessing the suita bility of existing valve assets and offers a reali stic pathway for supporting the UK's hydrogen tran smission ambitions while maximising the value of e xisting infrastructure.
