The pipeline type of the oil and gas station is diverse, and the single detection method is difficult to comprehensively and accurately measure the pipeline stress. According to the characteristics of each detection method, non-contact pipeline magnetic detection(NPMD), metal magnetic memory(MMM), ultrasonic stress measurement (USM), and ultrasonic thickness measurement (UTM), which constitutes the collaborative detection strategy of station pipelines. According to the sensors arrangement of the non-contact pipeline magnetic detection device, the pipeline magnetic abnormal evaluation parameter N is derived. The magnetic field distribution based on the different extraction height determined by the magnetic charge model and the experimental results, and constructs a feature parameter E which can characterize the degree of stress concentration. The pipeline stress concentration points can be quickly determined in accordance with N and E. Reference stress values can be measured using ultrasonic stress measurement and ultrasonic thickness measurement. Monitoring is implemented at the stress concentration points, and the true stress value at the stress concentration points of the pipeline is established by combining the stress detection results. The application is performed in an oil and gas station, and the collaborative detection method identified two stress concentrations of 186.7 MPa and 211.6 MPa, respectively. The stress at this point in the excavation pit one is confirmed to be 196MPa based on the monitoring data. Based on collaborative detection and on-line monitoring, fast and efficient collaborative detection and real-time mastering of station pipeline stress are achieved.
