Pipescan MFL Pipeline Corrosion Detection System

Cost-Effective Magnetic Flux Leakage (MFL) Pipe Screening System
Read More

Pipescan is an easy-to-use, cost-effective, portable, magnetic-flux leakage (MFL) inspection system for rapid screening and detection of random internal corrosion in pipe runs and small-diameter vessels.

The latest magnetic material coupled with unique mechanical designs enables covering all pipe diameters 48–2400 mm (1.9–94.5 in) with a limited selection of scanner heads.


  • Fast, reliable pipe and small vessel screening
  • Flexible heads fit a range of pipe and vessel sizes
  • Simple to operate with minimum training to semi skilled operator
  • High probability of corrosion detection
  • Rapid screening of complete pipe work with higher probability of detection than UT spot readings
  • Use in conjunction with UT follow up for quantifying any indications
  • Proven MFL technology
  • Field-proven durability and reliability

In-Service Inspection

MFL inspection is unaffected by product flowing through pipes, therefore surveys can be performed in or out of service, at surface temperatures up to 90 °C (194 °F). Using Pipescan, with its high probability of detection (PoD) to locate corrosion and ultrasonic validation, provides a cost-effective, accurate system to determine plant integrity.

MFL Control Module

The easy-to-use Pipescan system consists of a scanner head and a rechargeable battery-powered portable MFL control module that supplies up to eight hours of operation. The same control module can be used with the Handscan MFL floor scanner. The control module features audible and visual alarms to alert operators to the presence of corrosion during scans. Alarm sensitivity is adjustable, making it possible for operators to calibrate Pipescan to detect corrosion above the defined reporting level, but ignore low-level, irrelevant corrosion signals.

How It Works

The operator first connects the sensor cable to the scanning head and the MFL control module. The control module is then turned on, the required wall thickness configured, and then the alarm sensitivity adjusted using a reference pipe with known artificial defects. Then, the operator simply sets up the scanner head on the pipe under test, pushes the scanner head, and monitors the control module for alarms.

Any area identified by Pipescan can be marked on the pipe for further analysis using a secondary inspection technique, usually ultrasonic testing. For detailed corrosion mapping, we recommend RMS2 and Thetascan.
