В работе изучено влияние чистого газообразного водорода под давлением до 10 МПа на изменение механических характеристик основного металла труб большого диаметра (ТБД). Исследование проводилось при предварительном наводороживании в стационарном автоклаве под давлением, а также при одновременном нагружении с малой скоростью деформации (SSRT) в ожидаемых условиях эксплуатации. Результаты исследования металла ТБД Х52 показывают отсутствие существенного влияния воздействия газообразного водорода под давлением в течение 24 – 144 ч на механические характеристики основного металла, определяемые при статическом одноосном растяжении (снижение пластических характеристик не превышает 9 %). При испытании SSRT со скоростью не более 1·10–6 с–1 в среде чистого газообразного водорода под давлением 10 МПа изменение прочностных и пластических характеристик не превышает 13 % в сравнении с контрольными испытаниями в среде азота под тем же давлением. Полученные результаты позволяют считать основной металл низколегированной трубной стали с феррито-перлитной микроструктурой класса прочности X52 достаточно устойчивым к водородному охрупчиванию. Окончательным подтверждением возможности применения ТБД из исследуемой стали будут служить результаты дальнейших квалификационных испытаний, включающих изучение свойств металла шва и зоны термического влияния.</p></abstract><trans-abstract xml:lang="en"><p>In order to assess the resistance to hydrogen embrittlement caused by the presence of hydrogen in the transported product, and, accordingly, the suitability of pipes for transporting hydrogen, we studied the metal of large-diameter X52 strength class pipes manufactured by JSC “ChelPipe” (a TMK Group company). The work included the study of pure gaseous hydrogen effect under pressure up to 10 MPa on change in mechanical characteristics of the base metal of large-diameter pipes (LDP) during preliminary hydrogen charging for various periods in a stationary autoclave under pressure, and during simultaneous loading with a slow strain rate (SSRT) under expected operating conditions. Results of the X52 LDP metal study show that there is no significant impact on the effect of gaseous hydrogen under pressure for up to 144 hours on mechanical characteristics of the base metal determined by static uniaxial tension (decrease in ductile characteristics does not exceed 9 %). During SSRT at a rate of not more than 1·10–6 s–1 in a pure gaseous hydrogen environment under a pressure of 10 MPa, the change in strength and ductile characteristics does not exceed 13 % in comparison with the reference tests in a nitrogen environment under the same pressure. The results obtained allow us to consider that the base metal of low-alloy pipe steel with ferrite-perlite microstructure of X52 strength class is sufficiently resistant to hydrogen embrittlement. Final confirmation of the possibility of using LDP made from steel under study will be the results of further qualification tests, including the study of the weld metal and heat-affected zone properties.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сталь трубопроводная</kwd><kwd>водородное охрупчивание</kwd><kwd>испытания при малой скорости деформации</kwd><kwd>транспорт водорода</kwd><kwd>трубопровод большого диаметра</kwd><kwd>Х52</kwd><kwd>испытания на растяжение</kwd><kwd>автоклав для испытаний в среде водорода</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pipeline steel</kwd><kwd>hydrogen embrittlement</kwd><kwd>slow strain rate test</kwd><kwd>hydrogen transport</kwd><kwd>large diameter pipeline</kwd><kwd>X52 steel</kwd><kwd>tensile tests</kwd><kwd>autoclave for testing in a hydrogen environment</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при поддержке ПАО «ТМК» и Министерства науки и высшего образования Российской Федерации  (контракт № 075-15-2022-311).</funding-statement><funding-statement xml:lang="en">The research was supported by the Ministry of Science and Higher Education of the Russian Federation as part of the World-Class Research Center program: Advanced Digital Technologies (contract No. 075-15-2022-311 dated 20 April 2022).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Чугунов А.В., Бебешко И.Г., Семенов А.М., Беккер В., Фенин К., Хечер Т.
