Eddy Current Inspection

Specialist Inspection – Comprehensive Reporting, Quality Inspection Every Time.

Eddy Current Inspection

Eddy current testing (ECT) is used extensively within TesTex powering many of our technologies. We used ECT for the following types of inspection:

  • Eddy Current Weld Inspection
  • Eddy Current Tube Inspection from the I.D
  • Low Frequency Electromagnetic Technique (LFET) Pipe Scanning
  • Low Frequency Electromagnetic Technique (LFET) Tank Floor Scanning
  • Corrosion Under Insulation Scanning through Insulation

Eddy Current Technology uses electromagnetic fields to induce eddy currents within the test piece. Different methods exist for different types of technologies, but the general premise is to measure the changes in the eddy currents to detect defects in the material.

Weld Testing

Eddy current weld testing can be used in place of magnetic particle inspection, or dye penetrant inspection, and has the advantage of being able to penetrate through paint and other nonferrous coatings up to approx. 4mm.

Tube Inspection

Eddy Current Tube Inspection is great for nonferrous tubing, and provides rapid inspection compared to other types such as IRIS. ECT tube inspection can record and save tube data rapidly, to then be analysed by a technician at a later date.

Low Frequency Electromagnetic Technique

LFET is a technology we use in our in house technologies, such as our tank floor scanner, capable of corrosion mapping, and differentiating between topside and bottomside pitting and wall loss.

We also utilise the technology in our LFET pipe scanner & flat hand scanner, for use on corrosion screening on assets from the outer diameter. Often used on pipelines, tank shells, columns, pressure vessels and other assets.

Corrosion Under Insulation

Our CUI system is capable of detecting CUI occurring beneath insulation on a pipeline without the need to take any of the insulation off. The hand scanning tool can be pushed by hand to reach any accessible areas and record what is happening on the topside of the pipe beneath the insulation.
