Gazprom Portovaya LNG
Launching this facility is crucial for the economic and social development of the nation. It will increase
Russian LNG exports, as well as liquefied petroleum gases (LPG). The production of ethane, which is in
high demand by the domestic industry, will increase significantly.
High-strength pipes specially developed for this project were used to build a gas transportation system in the extremely harsh natural conditions of Yamal.
For this project, Severstal was the first domestic company to develop the production of Cryonix X7Ni9 — cryogenic steel, according to the EN standard, with a 9% nickel content.
This novel steel was developed as part of the Import Substitution Program for construction materials, tightly cooperating with Gazprom.
Cryogenic steel Cryonix X7Ni9 shows high resistance to cold at low temperatures (as low as minus 196 °C) and is designed to be used in making inner shells for liquefied natural gas (LNG) storage tanks.
In 2018, Severstal’s Steel Service Center in Kolpino manufactured of these sheets about 700 tonnes of structural elements to be used in the construction of the LNG storage tank at the Portovaya CS.
Cryogenic steel Cryonix X7Ni9 is certified according to the European quality norms and standards, which enables Severstal to participate in projects that require CE certification.
