钢制轻烃球罐 H2S应力腐蚀裂纹(SSCC)
鋼製輕烴毬罐 H2S應力腐蝕裂紋(SSCC)
강제경경구관 H2S응력부식렬문(SSCC)
对吉林和大庆地区钢制轻烃球罐运行中普遍存在的多发性裂纹状况、形式、性质、影响因素、成因和机理进行了试验研究。指出介质中较高的H2S含量，焊接区存在脆硬的粗晶马氏体组织，较高的焊接残余应力和壳材中S、P等杂质元素的偏析是导致该种裂纹的根本原因。

대길림화대경지구강제경경구관운행중보편존재적다발성렬문상황、형식、성질、영향인소、성인화궤리진행료시험연구。지출개질중교고적H2S함량，한접구존재취경적조정마씨체조직，교고적한접잔여응력화각재중S、P등잡질원소적편석시도치해충렬문적근본원인。
Situation,type,character,affected factors,cause and mechanism of regular cracks for steel light-hydrocarbon spherical tanks in Daqing and Jilin zone were studied.The results showed that the higher H2S content in active medium,brittle-hard gross-grain martensite strcture in welded zone,larger welding residual stress,segregation of S and P etc.impurity in shell material were main cause for above cracks.
