摘要
文章论述了应用于最小100 ksi无缝钢管开发和生产的第一阶段和用于评价高强度无缝钢管可焊性的第二阶段的主要成果。第一阶段和第二阶段取得了保证最佳强度-韧性的主要显微组织。采用苛刻的质量认定配制如API RP2Z对热影响区(HAZ)特征进行了界定,在典型海洋运行的环焊缝的结果。
The main results from both phase I devoted to the development and production of seamless pipes with minimum 100ksi and phase II devoted to evaluate the high strength seamless pipe weldability will be addressed in this paper. Main microstruetural features promoting the best strength - toughness results obtained from phase I and the results from phase II, where the heat affected zone (HAZ) characterization made using stringent qualifying configuration such as API RP2Z and the promising results after qualifying the girth welds simulating a typical offshore operation and the engineering critical assessment for installation will be addressed.
