Navigating the Challenges of Hydrogen Infrastructure in Pipelines
Key Ideas
  • Hydrogen pipelines present unique challenges due to hydrogen's small molecular size and potential for embrittlement, requiring specialized fittings and materials to ensure safety and reliability.
  • PLIDCO® has developed repair fittings specifically designed for hydrogen service pipelines, meeting ASME B31.12 standards and offering features like resistance to embrittlement and high-pressure capabilities.
  • The adoption of hydrogen-compatible products, like PLIDCO®'s fittings, is crucial for ensuring asset integrity and minimizing risks as the global deployment of hydrogen accelerates in the energy sector.
  • Mechanical fittings provided by PLIDCO® offer a safe alternative to in-service welding, providing detailed installation guidance and 24/7 engineering support for operators dealing with hydrogen infrastructure.
As hydrogen gains prominence in global decarbonisation efforts, the infrastructure, particularly pipelines, faces new challenges due to hydrogen's unique properties. Hydrogen's small molecular size increases the risk of leaks by permeating flaws in seals and joints, while its potential for embrittlement in metals necessitates specialized fittings. The article discusses the key criteria required for hydrogen service pipeline fittings, including material selection, seal tightness, resistance to embrittlement, and pressure/temperature ratings. PLIDCO®, a company specializing in high-pressure pipeline repair, has developed dedicated repair fittings for hydrogen pipelines that meet stringent criteria. These fittings are manufactured with hydrogen-resistant materials, designed for high-pressure systems, and tested rigorously for performance. They offer attributes like long sealing surfaces, compliance with ASME B31.12, and custom fittings for different operational needs. The installation and maintenance considerations for hydrogen pipelines are also highlighted. Welded joints are preferred to minimize leaks, but in-service welding can be risky, making mechanical fittings a safer alternative. PLIDCO®'s fittings come with detailed installation guidance and round-the-clock engineering support, ensuring proper installation and maintenance. With the increasing deployment of hydrogen, ensuring asset integrity is paramount. Adopting hydrogen-compatible products is emphasized not just for compliance but for enhancing safety and reliability in the evolving energy landscape. PLIDCO®'s hydrogen-ready fittings, backed by a ten-year warranty, offer operators peace of mind and long-term protection. These fittings are available in Australia and the Oceania region through Tremco Pipeline Equipment, the exclusive partner of PLIDCO® in the region since 2000.
