Severstal Deliver 27KT Large Diameter Pipes for Arctic LNG 2

PJSC Severstal has completed the supply of large-diameter pipes in the amount of 27 thousand tons for the development of the Salmanovskoye

PJSC Severstal has completed the supply of large-diameter pipes in the amount of 27 thousand tons for the development of the Salmanovskoye (Utrennoye) oil and gas condensate field under the Arctic LNG 2 project, which is being implemented by NOVATEK ". In the period from September 2020 to February 2021, the Izhora Pipe Plant (ITZ, part of the Severstal Russian Steel division) shipped large diameter pipes (LDP) in the range of 530-1420 mm with a three-layer polyethylene coating with a wall thickness of 14 to 26 mm made of steel of strength category from K50 to K60. Within the framework of this tender, Severstal also supplied 40 tons of LDP with a diameter of 1020 mm and a wall thickness of 26 mm in a cold-resistant design with a minimum operating temperature of -52 degrees. This is a unique product that has no analogues in Russia. Even at such a low temperature, the metal retains its ductility, which is important for the operational reliability of the gas pipeline in regions with extremely low temperatures.

Severstal offers customers unique trading solutions for the construction of LNG plants based on the production capabilities and products manufactured by the enterprises that are part of the structure of the company. For the construction of Arctic LNG 2, Severstal supplies the widest range of products from fittings, hardware and large-diameter pipes to the most sophisticated unique equipment, replacing imported counterparts.

In St Petersburg, Linde Severstal, a joint venture with Germany's Linde, is currently producing a spiral-wound heat exchanger (liquefier) for the Arctic LNG 2 project. The spiral wound heat exchanger (SVTO) is a key piece of equipment in natural gas liquefaction and processing plants. At the end of 2019, a 300-ton winding machine was purchased at the enterprise, which allows winding operations for large-capacity heat exchangers, which include a spiral-wound heat exchanger for Arctic LNG 2.

For the construction of Arctic LNG 2, Severstal-metiz (the enterprise is part of the Severstal structure) supplies fasteners, steel shaped profiles and reinforcing strands. High-strength fasteners are produced by Orlovsky Steel Rolling Plant in cooperation with the partner company Parallel, which applies a special thermal diffusion coating to the fasteners to protect them from corrosion. OSPAZ fasteners are used for fastening metal structures.

Severstal Distribution (Severstal's distribution network) supplies A600C and A500 valves for the construction of the Arctic LNG 2 liquefied gas plant. The total volume of supplies, starting from 2019, has already amounted to 92.5 thousand tons.

The Arctic LNG 2 project provides for the construction of three technological lines for the production of liquefied natural gas with a capacity of 6.6 million tons per year each and stable gas condensate up to 1.6 million tons per year. The total capacity of the three lines will be 19.8 million tons of LNG per year. The project is based on an innovative construction concept using gravity-based foundations in order to reduce capital costs and minimize the environmental impact of the Arctic region of Russia. The launch of the first line is planned in 2023, the second and third - in 2024 and 2026, respectively.
