Abstract

Abstract: To ensure the safe operation of buried oil and gas pipelines, a pipeline integrity assessment model was built based on combination of the technology of magnetic flux leakage detection and grading evaluation. Then the specific implementation process of the model was discussed in detail. The model was divided into two stages, a detection stage and an evaluation stage. The former included selecting the pipe segment to be evaluated according to the pipeline risk assessment and high consequence area evaluation results, pigging, launching detector, detection data analysis and testing results verification. The latter included three levels of evaluation methods. Evaluation equation was taken as the lowest level of evaluation and the finite element analysis method was used as the highest level evaluation method. The detection data obtained by the detection stage was transmitted to the evaluation stage in this model. The model was used to assess the integrity of a certain products pipeline in China. The results show that the model is suitable for data transmission and all defects detected are in a safe state.

Key words: pipeline, integrity assessment, magnetic flux leakage detection, grading evaluation, finite element analysis
