Research on the Application of Risk Based Online Inspection Technology for Pressure Pipelines
The 946 pressure pipelines of a petrochemical gas separation and alkylation unit need to be regularly inspected upon expiration,and the enterprise cannot stop for maintenance.Therefore,a technical institution was commissioned to implement risk-based online inspection technology.By combining RBI risk assessment technology with online inspection technology,the pipeline inspection strategy was reasonably optimized.Then,safety hazards were identified through online inspection technology to guide the enterprise in reducing defects in a timely manner.The risk-based online inspection technology was applied to adjust the pressure pipeline inspection cycle reasonably,achieving long-term safe operation of the pipeline without stopping.
