摘要
介绍了输气管道的硫化物应力腐蚀 (SSC)的危害性 ,分析了 SSC特征及产生的条件和机理 ,指出硫化物应力腐蚀的两大控制因素——材料韧性因素和介质因素。通过抗 SSC性能试验 ,给出了 SCC的评价方法和抗
This article introduced the disservice of SSC of the pipeline, analyzed the SSC character, conditions of its producing and mechanism, and indicated two control factors of SSC-material toughness and the medium. Through the anti-SSC test, Pointed out the SSC evaluation method and effective method of anti-SSC.
