TUBE INSPECTION – ECT, RFT &MFL

Tube Inspection with Eddy Current Testing (ECT)

  • Condensers
  • Feed water heaters
  • Heat exchangers
  • Air conditioners

Eddy current testing is a noncontact method used to inspect non ferromagnetic tubing. This technique is suitable for detecting and sizing metal discontinuities such as corrosion, erosion, wear, pitting, baffle cuts, wall loss, and cracks in nonferrous materials.

Tube Inspection with an Internal Rotating Inspection System (IRIS) for Ferrous and Nonferrous Materials

  • Boilers
  • Feed water heaters
  • Air coolers
  • Heat exchangers

The ultrasonic IRIS option is used to inspect a wide range of materials, including ferrous, nonferrous, and nonmetallic tubing. This technique detects and sizes wall loss resulting from corrosion, erosion, wear, pitting, cracking, and baffle cuts. Olympus digital IRIS inspection technology is used extensively as a prove- up technique for remote field testing, magnetic flux leakage, and eddy current inspections.

Tube Inspection with Remote Field Testing (RFT)

  • Boilers
  • Feed water heaters
  • Carbon steel heat exchangers
Remote field testing (RFT) is being used to successfully inspect ferromagnetic tubing such as carbon steel or ferritic stainless steel. This technology offers good sensitivity when detecting and measuring volumetric defects resulting from erosion, corrosion, wear, and baffle cuts.

Tube Inspection with Magnetic Flux Leakage (MFL)

  • Feed water heaters
  • Air coolers
  • Carbon steel heat exchangers
Magnetic flux leakage (MFL) is a fast inspection technique, suitable for measuring wall loss and detecting sharp defects such as pitting, grooving, and circumferential cracks. MFL is effective for aluminum-finned carbon steel tubes, because the magnetic field is almost completely unaffected by the presence of such fins.
