Corrosion Detection, Sizing & Mapping Floor Scanner

floormapvs2i_mfl_tank_inspection2The FloormapVS2i is latest version of the best selling MFL (magnetic flux leakage) floor scanner and it now comes with up-graded magnets to improve defect detectability and sizing on thicker materials, faster data capture with a custom designed micro controller and all new software.

The VS2i contains significant improvements in terms of defect positioning, electronic data processing and software manipulation.

A new High Specification encoder system has been developed that is electronically calibrated to each individual MFL scanner, eliminating the errors caused by component tolerances. The new encoder now gives accuracy to within 3mm on an 8-metre track length and, providing it is calibrated on an annual basis, it will not be affected by normal wear and tear.

The ruggedised on-board computer uses touch-screen technology for ease of use within the hostile storage tank environment. The custom-designed data acquisition software not only captures all the MFL signals, but analyses and displays the location and severity of the corrosion in real time.

  • Automatic CAD drawing
  • Patch plate design feature
  • Ruggedised touch screen computer
  • Real time data acquisition and analysis
  • Hard copy and electronic report functions
  • Combined defect profiling and amplitude analysis
  • Add data from Visual, UT, Vac box and MPI Inspection

The off-line reporting software automatically produces a CAD drawing of the tank floor with the defects being positioned to within 3mm accuracy. All captured data, over 20 percent loss of the nominal plate thickness, is re-analysed to identify the defect profile and separate the corrosion into one of three classes.

Different sizing algorithms are applied to each class of corrosion ensuring enhanced defect sizing even on badly corroded floors where small diameter deep pits may otherwise have been undersized.

Additional data from visual, ultrasonic, vacuum box and magnetic particle inspection can be added to the report, generating a full fingerprint of the tank floor including the annular plates. An innovative feature of the software allows subsequent inspection data to be overlaid and corrosion growth identified.

These features, coupled together with a patch plate design function and full statistics package, give the tankage engineer a powerful, cost effective MFL floor scanning tool to carry out trending and asset life projections.
