Ten years of rapid development in chemical engineering equipment – praise for China’s prosperity and strength. This is just a starting point; more participation will make things even more lively. HaiChuan becomes even better with your involvement; we welcome everyone to join in the forum discussions and exchanges. ********************************************* On February 10th, the China Petroleum and Petrochemical Equipment Industry Association organized an evaluation meeting for the “JQ·X80 solid welding wire for full-position welding of X80 pipes” product, which was developed jointly by the Project Management Branch of **PetroChina Pipeline Network Group Co., Ltd., China National Petroleum Corporation Engineering Materials Research Institute Co., Ltd., and Tianjin JinQiao Welding Materials Group Co., Ltd. Following inquiries and discussions, the evaluation committee unanimously agreed that the product features significant technical innovation, with its overall technology reaching a leading level in the country. 　　At present, solid welding wire products for high-strength oil and gas pipelines are almost monopolized by Western countries such as the United States and Germany. The appraisal committee believes that the solid welding wire products developed in this project have performance comparable to those of foreign products; they have been successfully tested and applied in projects such as the middle section of the West Third Pipeline, and are ready for wider deployment. They hold great significance for breaking foreign monopolies and improving China’s technical level in terms of solid welding wires for high-grade oil and gas pipelines. Zhang Guanjun, secretary-general of the China Petroleum and Chemical Industry Association, said that the products developed under this project fill a gap in the domestic market; they are valuable tools for oil and gas pipeline construction, offering significant social benefits and promising future prospects.
