Abstract
This paper mainly focuses on the limitations of the traditional detection technology and the harmfulness of pipeline corrosion in pressure piping.Through the analysis of corrosion principle under insulation layer,combined with the technology of ultrasonic guided wave, the petrochemical enterprise pipeline corrosion status was detected.Through actual experiment the insulation layer was removed to verify the feasibility of this detection technique.The data collection and analysis comparison were given for the detection of the pipeline in the service insulation layer.Also for the detection of single defect point,the technique needed further adjustment;by setting critical threshold,the position and size of the defect could be obtained.This research can offer effective solution for the comprehensive assessment of industrial pipeline corrosion under petrochemical enterprise and the judgment of on-line detection.关键词
