Magnetic Flux Leakage (MFL) (Tank Floor Mapping/Pipe Scanning)

(Tank Floor Mapping/ Pipe Scanning)

1. Magnetic Flux Leakage (MFL On Tank Floor)

Magnetic Flux Leakage (MFL) Is A Magnetic Method Of Non-Destructive Testing That Is Used To Detect Corrosion, Pitting And Wall Loss In Steel Structures.

Magnetic Flux Leakage (MFL) Is Commonly Used For Inspecting Tank Floors In The Petrochemical Industry. Corrosion Of The Tank Floor Can Lead To The Loss Of Product And Cause Damage To The Environment. Therefore, It Is Vital That Tank Floor Inspections Are Carried Out In Order To Prevent The Occurrence Of Such Problems.

The Method Uses Permanent Or Electromagnets To Magnetize The Tank Floor And The Resulting Magnetic Field Changes Are Recorded And Analyzed. If There Is Corrosion, Pitting Or Wall Loss, The Magnetic Field ‘Leaks’ And The ‘Leakage’ Is Analyzed To Determine The Location And Severity Of The Defect Of The Tank Floor – Both Near And Far Surface. A Map Of The Corroded Areas Is Provided With The MFL Method And This Essential Data Can Be Stored For Future Reference And Planning.

2. Magnetic Flux Leakage (MFL On Pipeline)

Magnetic Flux Leakage (MFL) Is A Magnetic Method Of Non-Destructive Testing That Is Used To Detect Corrosion, Pitting And Wall Loss In Steel Structures.

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.

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
