摘要
通过对X80高钢级直缝埋弧焊管力学性能试验研究,得到了各项力学性能参数,并对其数据进行了分析。研究表明:新开发的X80级管线钢力学性能已达到APISPEC5L标准,但需要进一步优化焊接工艺,提高焊缝的冲击韧性。
Each mechanical properties parameter obtained and its data analyzed through investigation to mechanical properties test of Grade X80 high grade longitudinal submerged arc welded pipe.The investigation indicates mechanical properties of new developed Grade X80 pipeline steel has meet the requirement of API SPEC 5L,however the welding procedure need further optimize to improve the impacting toughness of weld seam.
