Weak Magnetic Stress Detector

Weak magnetic stress detector is based on the magnetic memory characteristics of metals, 

utilizing the inverse magnetostriction effect and hysteresis effect. 

By using a highly sensitive magnetic resistance probe, the signal is picked up 

in the residual stress concentration area of the pipeline for pipeline safety assessment.

Specification range: 8 "~56"

Identification scope:

·Changes in pipe diameter such as depression and ovality

·Pipeline characteristics such as circumferential welds, bends, and lengths

·Valves, tees, and other pipeline installations
