Control of Fracture Toughness of LSAW Pipes for Sichuan-East Gas Pipeline Project

  • 摘要: 韧性是钢管重要的综合性能指标,结合川气东送工程用直缝埋弧焊管的韧性试验测试结果,分析了钢板化学成分、微观组织,焊丝、焊剂匹配,焊接线能量控制对钢管断裂韧性的影响。阐述了高强度管线管断裂韧性的控制因素。由断裂韧性试验结果可知,该工程用直缝埋弧焊管的断裂韧性优良。
    Abstract: Toughness is regarded as one of the critical properties of steel pipes. Based on the results of the toughness tests as made to the LSAW pipes to be used for the Sichuan-East Gas Pipeline Project, the main factors as influencing the fracture toughness of the steel pipes are analyzed, including the chemical composition and micro structure of the steel plate, matching of the welding wire with the welding flux, and the welding heat input, etc. Also discussed are the elements to be controlled for proper fracture toughness of the hi-strength linepipe. The result of relevant fracture toughness test shows that the fracture toughness of the said LSAW pipes is excellent.
