MFL
MFL can complete the detection of pipe defects, metal loss, pipe material changes, internal and external defect discrimination and pipe characteristics (pipe hoop, repair scars, bend, weld tee, etc.), and provide comprehensive information of defect area, depth, orientation, location and so on.
Our company produces and sells 6”-56” three-axis ultra-high-definition axial excitation magnetic flux leakage internal detector, above 28’’ series magnetic flux leakage internal detector with self-balancing speed control valve.

Technology
High-definition：
High density sensor layout: circumferential sensor spacing <2mm.
High-speed sampling: axial sampling spacing <1mm (when speed <5 m/s)。
Speed control system：
The speed control system is based on the principle of fluid mechanics, which automatically
adjusts the discharge flow rate and keeps the detector speed less than 4m/s.
Mass data storage:
Single runtime >200 hours.
Speed control system：
The speed control system is based on the principle of fluid mechanics, which automatically
adjusts the discharge flow rate and keeps the detector speed less than 4m/s.
Soft steel brush:
The soft fine steel brush will not damage the internal coating of the pipeline.4) Exclusive Service Engineer:
