Abstract
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.关键词
