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

Products

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).

Ultrasound

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

Probes

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

Wall Thinning – HRSG LFET

Wall Thinning – HRSG LFET

The Low Frequency Electromagnetic Technique (LFET) can detect and quantify wall thinning on HRSG finned tubes from the outside surface through the fins. As the LFET scanner moves along the tube surface, it measures the strength of the return signal that is transmitted into the tube by the scanner’s exciter coil. This technology is able to detect both localized and general wall loss such as pitting, under deposit corrosion and flow accelerated corrosion.
