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.

“Things went well. Shawn and Lexi definitely paid for their trip out here.
6 tubes have what appears to be damage. 4 were found with LFET and 2 were under the scaffolding that Shawn found with UT. I also confirmed everything. I’ll let you know what we find after we cut them out.
Depending on what we find when we cut, and there is no reason to believe we will not find huge deposits and corrosion, I will recommend a complete LFET scan for the next outage on the lower slope and the rear wall up to the replacement line, about 40 linear feet, in addition to some side wall scanning and the lower slope of the bullnose.”
