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.

Pressure Vessel Inspection

Pressure Vessel

Using our own Low Frequency Electromagnetic Technique (LFET) and Balanced Field Electromagnetic Technique (BFET) equipment, TesTex offers a variety of internal and exterior pressure vessels inspections.

Pressure Vessel LFET Waveform
Waveform shows localized wall loss of a pressure vessel.

Wall plates are inspected with LFET equipment, like the Falcon Jr., and welds are tested with the BFET-based TesTex Hawkeye Crack Detection System. Thus, TesTex can perform complete inspections of your pressure vessels.

Pressure Vessel BFET Waveform

Our highly trained staff can also provides dye penetrant, magnetic particle, and ultrasonic inspections as well as provide an appropriate American Petroleum Institute (API) inspections when required.

For those clients with boilers, TesTex, Inc. provides D/A Tank (Deaerator) inspections, too. Testex, Inc. has also performed pressure vessel inspections on process columns, mixing/agitation vessels, and reactors.

  • Fast and accurate inspection of wall plates from the inside or outside of the pressure vessel using LFET
  • Complete inspections can be conducted using LFET and Hawkeye Crack Detection System
  • Ability to perform various inspection methods as well as provide appropriate API inspections
