Application of SAFETI in the Analysis of Natural Gas

Based on natural gas hazard properties analysis, this paper systematically summarized the types of the natural gas pipeline leakage accidents and analyzed the toxicity and flammable characteristics of natural gas pipeline leakage with the help of quantitative risk analysis Software DNV SAFETI(Software for Assessment of Flammable, Explosive and Toxic Impacts). Corrosion Failure Analysis of an SA210 Steel Used in High The corrosion failure analysis of an SA210 steel used in high pressure evaporator tube is conducted by XRD, SEM, OM. The result shows that the corrosion products in the inner wall of the steel tube is Fe3O4, mainly caused by the residual water in the evaporator tube corroding its inner wall with oxygen after the hydrostatic test of the boiler, finally leading to the corrosion leak of the tube.
