Severstal Introduces Unique Cryogenic Valves

PAO Severstal, one of the world's leading vertically integrated steel and mining companies, a Metal-Expo regular exhibitor, has mastered the technology for the production of Ak500-class cryogenic valves. This is a new product of the Cryonix line, which retains its properties at temperatures down to minus 165 degree Celsius and is unique for the Russian metallurgy.

The production technology was developed in the production of long products and tube-shaped rolled products of the Cherepovets Metallurgical Plant together with experts on the development of the product category Long Products and the Directorate for Technical Development and Quality. The selected chemical composition, as well as the parameters of heating, rolling and cooling allowed the specialists to obtain the profile required in terms of mechanical properties that meets the requirements of domestic and foreign standards.

Cryogenic valves retain their properties at extremely low temperatures, which makes them applicable in narrow areas of industrial construction, for example, in the construction of terminals for liquefied natural gas. Cryogenic properties of the Cryonix Ak500 fittings have been confirmed by tests at leading research institutes.

The Cryonix product line includes rebar, cryogenic flat products and products from it, as well as promising developments such as large diameter cryogenic steel pipes. The joint venture Linde Severstal is a supplier of high-tech spiral heat exchangers.
