The paper applied RBI (Risk -based Inspection) technology on the PX apparatus in order to identify the highly hazardous medium and the damage type. Process hazard analysis and the damage mechanism analysis show the main damages are HTHA, temper embrittlement, external corrosion. Quantitative risk analysis result shows that there are 6 items (3.09%) in medium-high risk level, 153 items (78.87%) in medium risk level, and 35 items (18.4%) in low risk level. According to the risk level, the inspection plan is recommended and provides certain reference for risk identiifcation and lowering the risk of the apparatus.
