Stack Tower & Column Inspection

Specialist Inspection – Comprehensive Reporting, Quality Inspection Every Time.

Stack Tower & Column Inspection

We provide testing services for process columns. We can offer a variety of services such as:

  • Low Frequency Electromagnetic Corrosion Scanning
  • Eddy Current for Stress Corrosion Cracking Detection
  • Dye Penetrant Inspection for Welds
  • Corrosion Under Insulation scanning without removing insulation
  • Ultrasonic Thickness Survey
  • Full Visual Examination

Depending on the goal of the inspection, we will use different combinations of technologies & techniques. We also have teflon coated scanners for use at higher temperatures, as well as remotely operated crawlers to allow us to reach areas where there is typically no access.

Typically we’ll use ultrasonic testing to determine thicknesses and subsurface inspection of cracking, and welds. Low frequency electromagnetic technique (LFET) is used for fast screening, when looking for internal corrosion from the external side. We scan all areas where insulation has been removed and report any internal areas where corrosion is likely occuring, and then do more in depth investigation with ultrasonics to see exactly what is going on.

We also use more basic techniques such as dye penetrant (DPI) and magnetic particle inspection (MPI) to look for surface breaking cracking, such as stress corrosion cracking.
