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.

Stack, Tower, & Column

Stack Inspection Services
TesTex inspects stacks, columns, and towers in various types of process facilities.

Usually, these structures comprised of carbon steel, which is magnetic; so, our TesTex Viper Magnetic Crawler can be deployed when one cannot gain access via scaffolding or lifts to the area of concern. Data can be collect using either our LFET or ultrasonic products as well as our Hawkeye products.
