经过反复试验和不断优化,一种可在较大应变条件下安全工作的国产X80钢级抗大变形直缝焊接钢管,在宝鸡石油钢管有限责任公司成功下线,这不仅填补了国内同类产品的研发空白,而且进一步增强了中国油气输送制管领域的核心竞争力。近年来,随着天然气的开发、开采向沙漠、极地和海洋
After repeated tests and optimization, a domestic X80 steel grade large deformation straight seam welded steel pipe, which can work safely under a large strain condition, was successfully put under the control of Baoji Petroleum Pipe Co., Ltd. This not only filled the domestic similar products Research and development gaps, but also further enhance the core competitiveness of China’s oil and gas pipelines. In recent years, with the development of natural gas, exploitation to deserts, polar regions and oceans
