CRACK DETECTOR
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 electromagnetic method, which can effectively detect cracks in any direction of inner wall pipeline within 10mm, the internal cracks of the pipe wall, the internal cracks in circumferential welds and the internal cracks in straight welds.

Technology
All-round crack detection:
The balanced field crack detection method is not restricted by direction, and can detect axial cracks, circumferential cracks and various oblique cracks, realizing all-around crack detection.
The pipeline crack detector is based on the balanced field electromagnetic method, which can effectively
detect the intemal and extermal cracks of the pipe wall, the cracks at the circumferential welds and the cracks at the
straight welds.
It can detect cracks on the weld:
The cracks in the weld can be distinguished by the characteristics of the defect signal and the degree of amplitude change.
Service Advantage
