PIPESCAN Adjustable (MFL) magnetic flux leakage pipe screening system

  • Fast, reliable pipe & small vessel screening
  • Various scanning heads for multiple pipe sizes
  • Simple to operate
  • High Probability of corrosion detection

Pipescan is an easy to use, cost effective, portable, magnetic flux leakage inspection system for the 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 coverage of all pipe diameters from 48mm to 2.4 metres with a limited number of scanning heads.

In-Service Inspection

Magnetic flux leakage inspection is not affected by product flowing through the pipe so surveys can be carried out both on-line and off-line and at surface temperatures up to 90°C. Use of Pipescan, with its high probability of detection to locate the corrosion, coupled with ultrasonic prove up, provides a cost effective accurate system for the determination of plant integrity.

Key Features:
  • Flexible heads fit a range of pipe & vessel sizes
  • 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
  • Simple to operate with minimum training to semi skilled operator
  • Proven MFL technology
  • Field proven durability & reliability

MFL Control Module

The easy to use Pipescan system consists of a scanning head and a rechargeable battery powered portable MFL control module which provides up to 8 hours of operation. The same control module can be utilised with the Handscan MFL floor scanner The control module features audible and visual alarms to alert the operator to the presence of corrosion during a scan. The alarm sensitivity is adjustable, allowing the operator to calibrate the Pipescan to detect corrosion above the defined reporting level, but ignore low level, non-relevant corrosion signals.

How it works

The operator first connects the sensor cable between the scanning head and MFL control module. Switch on the control module, set the required wall thickness and adjust the alarm sensitivity using a reference pipe with known artificial defects. Then simply set up the scanning head on the pipe to be inspected, push the scanning head and monitor the control module for the audible and visual alarm. Any areas identified by the Pipescan system can then be marked on the pipe for further analysis by a secondary inspection technique, normally ultrasonic and for detailed corrosion mapping we recommend the RMS2 or Thetascan systems.
