%X 某含硫气井站场一法兰螺栓失效&#65292;通过金相分析、基体形貌及成分分析、腐蚀产物成分分析、力学性能测试等检验方法对其失效原因进行分析&#65292;结果表明&#65306;螺栓的腐蚀失效是由于螺母材质和螺杆材质不同、螺杆材质与不锈钢法兰材质不同及缝隙腐蚀造成。针对螺栓腐蚀失效的影响因素提出了具体对策。<br>The failure of a flange bolt in a sulfur gas well station was analyzed through metallographic analysis, matrix morphology and composition analysis, corrosion product composition analysis, mechanical property testing and other inspection methods. The results show that the corrosion failure of the bolt is caused by the different material of the nut and the screw, the screw and the stainless steel flange and the gap corrosion. Specific countermeasures are put forward according to the influencing factors of bolt corrosion failure.
