Application of electromagnetic eddy current technology in pipeline inspection
In order to ensure the safety of pipelines in the process of oil and gas transporta-tion,it is necessary to carry out defect detection of pipelines.Based on the principle of elec-tromagnetic eddy current,an electromagnetic eddy current detector was designed and cus-tomized.The application of the electromagnetic eddy current detection technology in the de-tection of the gathering and transportation pipeline in a natural gas block was described in detail,the quality of the collected data was evaluated,the data signals were filtered,and the internal metal loss points,abnormal points of the circumferential welds and dents were iden-tified.The residual strength of the identified anomaly points is evaluated,the residual life of the pipeline is predicted,and the next inspection date is agreed.By analyzing and verifying the adaptability and accuracy of the electromagnetic eddy current technology in the detection of natural gas pipelines,it provides a reference for the application of this technology in the detection of natural gas pipelines.
