焊接钢管技术的新进展

The New Development of Welded Steel Pipe Technology

介绍了近十几年国际管线钢管技术的新进展,包括陆地天然气管道用管、海底天然气管道用管以及大应变钢管和超高强度管线钢管的开发;焊管企业的现代化信息系统的建设及发展;我国高频直缝焊管、螺旋埋弧焊管和直缝埋弧焊管生产技术和装备的技术进步。建议我国焊管企业应加快设备改造和升级,以适应管线管向高性能、高钢级、大壁厚和高尺寸精度发展的要求;对无损探伤设备进行彻底更新,保证其可靠工作;通过信息化改造,实现从基础自动化到全线自动化、信息化的飞跃,进一步增强我国焊管企业的竞争力。

This paper introduced the new development of the international line pipe technology during the recent decade from several aspects,such as onshore natural gas line pipe,offshore natural gas line pipe,large deformation pipe and ultra-high strength line pipe;the construction and development of the modern information system in welded pipe corporation,and the advancement in production technology and equipment of the high-frequency longitudinal welded pipe,SAWH pipe and SAWL pipe.It suggested that China welded pipe corporations should accelerate the renovation and upgrading the equipment to meet the requirements of the line pipe with high properties,high grade,heavy wall thickness and high precision;updating the NDT equipment thoroughly to ensure it works reliable;to realize automatization from the foundation to whole-line through the information renovation,and then enhance competitive strength of China welded pipe corporations.
