摘要:
对某海底管线用X70级?准 765.2 mm×31.8 mm 直缝埋弧焊管进行水压爆破试验时,钢管爆破失效后出现了较严重的断口分离现象。爆管断口试样宏观形貌显示,断口上有3种形貌特征:即壁厚中心分离较深、两侧分离较浅和韧性剪切面。通过金相分析、能谱分析、扫描电镜等方法,对断口分离现象进行了分析研究。研究结果表明:MA带状偏析组织是造成此水压爆破断口分离现象的主要原因。
Abstract:
Hydraulic blasting test was conducted on X70 ?准 765.2 mm×31.8 mm SAWL pipe which was used in subsea pipeline,the serious fracture separation phenomenon occurred after steel pipe blasting failure. The fracture macroscopic appearance showed that 3 kinds of appearance feature exist,namely the deeper separation in the center of wall thickness,the shallower break at both sides of wall thickness and toughness shear area. The fracture separation phenomenon was analyzed and studied by metallographic analysis,energy spectrum analysis,scanning electron microscope and other methods;the results indicated that the MA banded separation structure is the main reason caused hydraulic blasting fracture separation.
