Abstract:
Taking the carbon steel elbow in REAC outlet pressure pipeline system of Zhenhai Refining & Chemical Company as example, combined with the erosion-corrosion failure mechanism, a mathematical model of fluid-structure interaction for erosion-corrosion failure was established. The interaction between erodent products protecting film and multiphase flow was analyzed by numerical simulation method. The distribution of shearing stress on the inner wall of elbow and the distribution of principal displacement, stress and strain of erodent products protecting film were revealed, and the erosion-corrosion failure process of petrochemical pressure pipeline was studied. The reliability of fluid-structure interaction numerical simulation method by the finite element analysis software was validated combining with field thickness measurement data, and the influence of characteristic parameters, such as flow characteristics of fluid and architectural characteristics of pipeline fittings etc., on erosion-corrosion were analyzed. It provides theoretical basis and analysis means for the erosion-corrosion failure analysis, structural optimization design, RBI and periodical inspection for thickness measurement and positioning, life prediction, risk assessment and other safety guarantee research of petrochemical pressure pipeline transportation system.
