in-line Inspection Tools
MFL can complete the detection of pipe defects, metal loss, pipe material changes, internal and external defect discrimination and pipe characteristics (pipe hoop, repa-ir scars, bend, weld tee, etc.), and provide comprehen-sive information of defect area, depth, orientation, location and so on (read more)
The MFL+TFI tool is composed of an axial excitation detection section and a circumferential excitation detection section. Circumferential excitation detection magnetic field is distributed along the circumferential direction of the pipe wall, which can detect axial defect signals, and has strong detection ability for axial grooves. Axial excitation detection data and circumferential excitation detection data complement each other to realize omni-directional detection. (Read More)
The self-propelled robot can complete the detection work through autonomous crawling, which can implement the geometric deformation detection and centerline mapping before the new pipeline is put into production, providing basic data for the new pipeline. (Read More)
The caliper tool can detect the depression, ovality deformation, wall thickness change of the pipeline, and various pipeline accessories that cause the inner diameter of the pipeline to change. (Read More)
Cracks are one of the most dangerous defects in long-distance pipelines, and they are also the main cause of pipeline failure. The occurrence and expansion of cracks will cause stress concentration in the pipeline, which is prone to failures such as brittle fracture, fatigue damage and corrosion damage. Detection can improve the performance and reliability of the pipeline. The pipeline crack detector is based on the balanced field electromag-netic method, which can effectively detect the internal and external cracks of the pipe wall, the cracks at the circumferential welds and the cracks at the straight welds.

The pipeline stress concentration inspection technology utilizes different recognition rates of the stress magnetic signal under different excitation intensities to achieve stress detection. It can be carried out simultaneously with the MFL and remain unaffected. It is a new and efficient stress concentration detection method. (Read More)
