At TesTex, we know your turnaround depends on our turnaround.


TesTex uses a variety of state-of-the-art electromagnetic techniques to scan for defects in both ferrous and nonferrous materials and structures.

LFET Products

Low Frequency Electromagnetic Technique (LFET) products are used to inspect storage tanks, other convex or concave ferrous surfaces, as well as nonferrous metal tubing/piping surfaces.

RFET Products

Remote Field Electromagnetic Technique (RFET) products are used to quickly and accurately inspect ferrous tubing found in heat exchangers and drum-to-drum boiler generating banks.

BFET Products

Balance Field Electromagnetic Technique (BFET) products are used to detect surface and sub-surface cracking in welds and base metals.

ECT Products

Eddy Current Technique (ECT) is used to quickly and accurately inspect non-ferrous metal tubing from the tube internal dimension (ID).


TesTex has enhanced ultrasonic (UT) inspection for many different applications, including tank shells, UT prove-ups, finned tubes and waterwalls.


TesTex produces standard and custom probes (and calibration tubes) for all of its ID (internal dimension) inspection equipment.


This is a great place to check out Technical papers, Case Studies, and any other relevant news related to our specialized non-destructive testing products and services.

Upstream Oil & Gas

Corrosion Cell

TesTex Inc. has a wide variety of services available to Upstream Oil Providers. We utilize a variety of Techniques:

  • Low Frequency Electromagnetic Technique
  • Ultrasonic Thickness Measurement
  • Mag particle & Dye Penetrant
  • Balanced Field Electromagnetic Technique

Low Frequency Electromagnetic Technique and Ultrasonic Thickness Measurement

Corrosion Cell
Waveform shows a corrosion cell on the shell of a tank.

Using our proprietary Low Frequency Electromagnetic Technique (LFET) we can quickly scan Tank Walls, Tank Floors, and Pipelines for potential problem areas. This allows us to quickly determine where Ultrasonic Thickness measurement needs to be done to determine areas of wall loss without the tedious preparation work needed for other techniques. For Tanks we can utilize our Falcon system for tank floor scanning, our hand scanners for tank walls, and our LineCat for scanning pipelines. All of these inspections can be done remotely utilizing three man crews and portable power sources. This allows us to deploy our work crews quickly to remote locations where these tanks and pipelines are usually situated.

Mag Particle / Dye Penetrant

Using techniques like Mag Particle and Dye Penetrant we can determine if there is an issue with weld cracking on vital points in the tank. This includes welds around manholes, plate welds, and structural add-ons like D-rings and lift points on tanks. Customers utilizing this type of inspection will receive a report with pictures to show potential problem areas, as well as a general visual inspection of the site to determine other potential issues. Additionally we have technologies like the Balanced Field Electromagnetic Technique (BFET) to help determine if cracking exists in welds. We have utilized this in the past for small welded areas like socket welds providing a much safer test than utilizing X-rays.
