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.

Tube to Header Weld Cracking – HRSG Claw

Tube to Header Weld Cracking – HRSG Claw

TesTex adapted the Balanced Field Electromagnetic Technique (BFET) to detect tube to header weld cracking in HRSG units. BFET sensors and cameras are placed on the welds using a C-clamp housing called “The Claw” that attaches to the tube. Once attached to the tube, the Claw moves circumferentially around the weld to detect cracking, lack of fusion, porosity and other defects. The Claw can be customized to inspect 1.5″ – 3.0″ diameters.
