分析了我国管线钢的发展趋势,详细介绍了未来十几年我国管道建设发展的前景规划.对我国几种典型管线钢生产工艺、管线钢的开发生产情况、组织特性、发展方向进行了分析.分析认为:大直径、高压力、大输量成为管道工业发展的一个主要趋势,未来的管线用钢将向更高级别、更大输送压力的方向发展.但是,也不能忽视对X70,X80管线钢的生产工艺、质量的稳定性及高效性的研究.此外,抗大变形、耐酸性腐蚀及抗应力腐蚀等性能也是未来管线钢发展的关注重点,应加强此方面的技术研究.%This article analyzed development trend of pipeline steel in China, detailedly introduced forward planning of pipeline construction development in the future l0-odd years in China, and analyzed situation of several kinds of pipeline steels from several aspects, such as production procedure, development situation, struction characteristics and development direction,the results indicated that large diameter,high pressure and great throughput is the main trend of pipeline industry development,the steel used in pipeline develop towards higher grade and transportation pressure,yet it can not oversight more effective study to production procedure, quality stability. In addition, large deformation resistance, anti-acidity corrosion and strain resistance corrosion and other properties are also attention points for pipeline steel development in the future, so it should strengthen technology research.
