The high-tech steel pipes used in this project were entirely manufactured and processed by Chinese companies from start to finish. The Sichuan Gas to East China pipeline project starts from the Puguang terminal in northeastern Sichuan and ends at the terminal in Shanghai; it is another major pipeline artery that runs across China’s eastern and western regions, following the West Gas to East China pipeline. On February 28, 2006, the preliminary work for the Sichuan Gas to East China pipeline project was officially launched. Sinopec Pipeline Company made decisive decisions throughout the process by opting for domestically produced X70-grade straight-seam submerged arc welded pipes, an action that has become a famous story in the industry.
