Corinth Pipeworks, Cenergy Holdings’ steel pipes subsidiary, is currently completing orders for 440 kilometers of pipes with Snam, one of the world’s leading energy infrastructure businesses.
The aforementioned orders are among the first in Europe for freshly built high-pressure pipes certified to transport up to 100% hydrogen for a transmission gas pipeline.
“We are very excited to be an innovative producer and early adopter, providing certified large diameter/high strength steel pipes for hydrogen transportation. The potential of hydrogen to build a sustainable energy mix in the future and achieve global decarbonisation targets is significant, and Corinth Pipeworks aims to be an integral part in providing solutions to its customers to reach their goals” said Ilias Bekiros, CEO of Corinth Pipeworks.
“This agreement confirms Snam’s commitment to making its infrastructure increasingly ready to transport not only natural gas and biomethane, but also hydrogen. While we are continuing with analysis and certification of our network, when we replace old pipelines, we now routinely use new pipes tested in the laboratory in line with international standards and able to transport hydrogen up to 100% without changing pressure.
Our goal is to deliver fully decarbonized gas by 2050” commented Massimo Derchi, Chief Industrial Assets Officer of Snam.Corinth Pipeworks’ plant in Thisvi, Greece, manufactured the entire number of hydrogen-certified pipes. Additionally, the scope of delivery comprises an external 3LPE anti-corrosion coating and an inside liquid epoxy liner applied concurrently with pipe manufacture.
Corinth Pipeworks has been a trusted supplier of Snam for over a decade, with over 1,000 kilometers of finished and under construction pipeline projects. Corinth Pipeworks and Snam have successfully completed the essential action plan for these gas line pipes to be certified for up to 100% hydrogen in the context of this jointly organized project.
The action plan included an analysis of hydrogen design codes, the development of pertinent qualification specifications and test procedures, the design of steel in accordance with recommended practices, and specialized long-term test campaigns to qualify weld and parent metal crack resistance at design pressure and 100% hydrogen. The action plan was developed in collaboration with RINA, an internationally recognized third-party certification agency with extensive experience in hydrogen testing and fracture mechanics.
