Corinth supplies hydrogen-certified pipeline for Snam project in Italy

Corinth Pipeworks supplies hydrogen-certified pipeline for Snam project in Italy

Corinth Pipeworks (a steel pipes producer and part of Cenergy Holdings) is supplying 440 km of pipes to Snam (an energy infrastructure company), which would be among the first high-pressure newly produced pipes certified to transport 100% hydrogen for a transmission gas pipeline in Europe.

Following the framework of ASME B31.12 Option B, the pipes, in L415ME steel grade with an outside diameter of 26” (660mm) and thicknesses of 11.1 mm & 15.9 mm, have been tested in the laboratory at maximum pressure and 100% hydrogen.

The pipes are manufactured in Corinth Pipeworks’ plant in Thisvi, Greece. The pipes have an external 3LPE anti-corrosion coating and internal liquid epoxy lining applied at the same location as pipe manufacturing. The pipes testing process considered the pertinent qualification specifications, test procedures, design of steel, crack resistance etc.

Ilias Bekiros, CEO of Corinth Pipeworks, said, “We are very excited to be an innovative producer and early adopter, providing certified large diameter/high strength steel pipes for hydrogen transportation.”

Massimo Derchi, Chief Industrial Assets Officer of Snam, said, “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.”

Corinth Pipeworks is also a part of the White Dragon project. The project proposal was submitted to the Greek call for expression of interest regarding Important Hydrogen Projects of Common European Interest (IPCEI) in May.
