This is just a starting point – more participation will make things even more lively. Haichuan becomes better with you all here; we welcome everyone to engage more in discussions on this forum. Happy May Day! A safe and secure Red May ********************************************* On May 17, 2023, it was learned from **PetroChina Pipeline Network Group Co., Ltd. (hereinafter referred to as **Pipeline Network Group**) that the first full-scale blast test of a carbon dioxide pipeline conducted in China by this group was successfully completed recently. This experiment provided important data support for China to master the technologies related to the development of million-ton-class carbon dioxide transmission pipelines, as well as pipeline design and construction, marking significant breakthroughs in China’s research in carbon capture, utilization, and storage (CCUS) technology. For this blasting test, pipes made of X65 steel grade with a diameter of 323.9 millimeters were used, and the test pressure was set at 12 megapascals. This setup accurately simulated the operating conditions of supercritical carbon dioxide pipelines. The important parameters obtained from the test, such as the pipe’s fracture resistance, will be used to validate simulation models of supercritical carbon dioxide pipelines, thereby improving the accuracy of calculations related to pipe fracture resistance. This provides an important technical foundation for the safe construction and operation of carbon dioxide pipelines worldwide.
