Crack arrest toughness and full-scale burst test were investigated in this paper,test results show that arrest stress of steel pipe depend on its natural properties,crack arrest stress was predicted correctly through crack-arrest test and full-scale burst test.Crack propagation or arrest depend on properties of pipe and transmission media.Should crack propagating pressure is higher than crack arrest pressure,crack propagation occur.
