On April 1, 2024, Cheng Yufeng, Academician of the Royal Canadian Academy of Sciences, Academician of the Canadian Academy of Engineering, tenured professor of the University of Calgary, director of the Center for Advanced Materials and Manufacturing, and National Chief Professor of the Canadian Energy Pipeline field, was invited to the school to give a lecture on "Energy Pipeline Corrosion, hydrogen embrittleness and Service Safety: From Basic Research to Engineering Application "academic report, chaired by Dean Cui Hongzhi.
President Cui presided over the presentation
Energy pipeline corrosion, hydrogen embrittlement and other problems seriously affect the safety of pipeline service. Academician Cheng introduced the research results obtained in detail from the aspects of hydrogen pipeline technology, CO2 pipeline, pipeline corrosion and service safety assessment. The concept of "metallurgical microelectrochemistry" was first proposed in the world, and a variety of micro-nano electrochemical techniques were applied to study pipeline corrosion phenomena, which greatly enriched the knowledge system of pipeline steel corrosion and stress corrosion cracking. The local electrochemical activity of nanoscale metallurgical and mechanical defects in pipeline steel in service environment was studied and determined. Mechanical-chemical interaction was applied to the study of pipeline corrosion, and "mechanical-electrochemical effect theory of pipeline corrosion" was first proposed. A "multi-physics coupling effect model" is proposed for pipeline safety assessment and failure prediction technology, and the research results are applied to the integrity management system of several international pipeline companies. Academician Cheng pointed out that currently hydrogen energy, as a clean fuel, plays an important role in the context of today's international energy transition. At present, the use of long-distance pipeline for large-scale long-distance efficient hydrogen transport has been listed as a priority technology in the development strategy of hydrogen energy by many countries. In view of the hydrogen embrittlement of carbon steel pipelines in high-pressure gas phase hydrogen environment, the uniqueness of hydrogen embrittlement in high-pressure gas phase environment is systematically analyzed, and the key techniques for studying hydrogen iron interaction and gas phase hydrogen embrittlement are put forward.
Academician Cheng gave a report
In the discussion session, the participating teachers and students actively asked questions and conducted in-depth exchanges on the corrosion of energy pipelines and hydrogen embrittlement. More than 100 students and teachers from the School of Materials Science and Engineering attended the lecture. The lecture was held at the Baichuan Forum of Ocean University of China, hosted by the Graduate School and hosted by the School of Materials Science and Engineering.
