JFE Steel has conducted extensive R&D on large-diameter welded steel pipe, to develop high-strength, thick-walled steel pipe with excellent low-temperature toughness, for example. To facilitate the manufacture of high-strength, thick-walled steel pipe, we streamlined the forming process, utilizing our “NEO Press^®” press bending method, while to meet more stringent low-temperature toughness requirements, we developed a new welding process that enhances the toughness of welded steel. The result is a high-efficiency, high-quality manufacturing system. The products created using this manufacturing technology for high-strength, thick-walled steel pipe are now being adopted to meet the high-grade steel pipe needs of large-scale projects by international oil majors.
