| Popis: | The liquidized natural gas (LPG) as well as other liquidized gases, as oxygen, nitrogen, ethylene etc. are widely used in the today’s world economy. A perspective of LPG and liquidized gases application presented, foreign and domestic experience in production of materials, used for manufacturing tanks and reservoirs, intended for storing and transporting of LPG, considered. Influence of chemical composition of cryogenic steels on resistivity to fragile destruction at negative temperatures studied. Influence of various alloying elements, including nickel, manganese, chrome, molybdenum and other elements on operating properties of cryogenic steels were also studied. Specialists of JSC “Ural Steel” together with scientists of JSC “NPO “CNIITMASH” elaborated a comprehensive technology of industrial production of plates of cryogenic steels. Based on literature data, domestic practice of designing and manufacturing cryogenic equipment, specifications of the required application plates were elaborated and approved. The rolling of plates of wide range of thickness of pilot heat 0H6 steel was carried out. At present, the thermal treatment modes of the 0H6 steel rolled products are being adjusted. |
