Tank Floor Scanners for Corrosion (Magnetic Flux Leakage)
A magnetic flux leakage (MFL) tank floor scanner finds corrosion and pitting on storage tank floor plates, including on the underside you cannot see, without damaging them. Asia NDE supplies the Baugh & Weedon TruFlux and TruFlux Mini tank floor scanners across Malaysia and Southeast Asia. We serve oil and gas and petrochemical customers, with calibration and repair support from our Subang Jaya office.

What it’s used for
- Screening storage tank floors for corrosion during out-of-service inspections.
- Finding underside (soil-side) and topside pitting on floor plates 6–20mm thick.
- Scanning edges, corners and areas under pipework with the compact TruFlux Mini.
- Producing floor maps and reports for tank integrity records.
Frequently asked questions
How is a storage tank floor checked for corrosion?
The tank is emptied and cleaned, then a magnetic flux leakage (MFL) scanner is moved across the floor plates. The scanner magnetises the steel, and corrosion on either side of the plate makes the magnetic field leak. Sensors record this leakage. Areas the scanner flags are usually checked with an ultrasonic thickness gauge.
Can a tank floor scanner find corrosion on the underside of the floor?
Yes. Magnetic flux leakage detects metal loss on both the top and the underside (soil side) of the floor plate, which you cannot see from inside the tank. The TruFlux works on floor plates from 6 to 20mm thick, and the TruFlux Mini reaches edges, corners and areas under pipework.
