Pipeline integrity assessment, corrosion diagnosis and failure analysis system, safety IoT Monitoring system
Spider-MX™
Automatic Magnetic Flux Leakage Pipe Scanner
Spider-MX™ is the automated inspection tools for exposed pipes.
Spider-MX™ is the carrier system which sticks to the pipe wall using magnetic forces, scans the full coverage of the pipes, saves the data, and analyzes the data.
Spider-MX™ software analyzes the scanned data, measures the width, length, and depth of defects in pipes and provides assessment on risk of failure.
Key Features
- Uses proven MFL(Magnetic Flux Leakage) Technology
- Self-sticks to the pipes using magnetic forces without any additional installation
- Allows flexible (axial and circular) movement for obstacle detection and avoidance
- Plans path using IMU sensor
- Scans the entire pipe with high speed
- Displays the scanned data in real time
- Provides a final inspection report and risk assessment report
In-Line Inspection
- Magnetic flux leakage inspection is not affected by liquid flowing through pipe, so inspections can be carried out for both active and inactive pipes.
Surface temperature of the pipe should not be higher than 80 oC.
Metal loss Inspection : Measurement Principle
Magnetic Flux Leakage(MFL) detection technology was a widely proven technology for detecting the metal loss of pipeline.
Metal loss features in the wall of pipe, saturated with magnetic flux, will cause some of the magnetic field to leak out of the pipe.
This leakage field can be detected by sensor and used to analyze feature classification. PI& has developed the high resolution and most
sensitive metal loss inspection tools named Spider-MX™, based on MFL technology and applies exposed pipe inspection.
Spider-MX™ consists of the following system ;
Magnetization system
Automatic carrier system
Odometer system
IMU system
Data acquisition system and
Data analysis system
