| 摘 要： | This paper introduced the research and development of large-diameter SSAW pipes applied to West-East Pipeline project as well as domestic acicular ferrite pipeline steel of X70 grade. Its microstructure analysis was performed in comparison with the pipeline steel of a foreign steel plant (SPC). This paper introduced the research of welding procedures prior to SSAW pipe making and some new procedures and technologies used for West-East Pipeline Project, and appraised the practical level of Large-diameter SSAW pipe applied to the West-East Pipeline Project.
