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.

(Lightweight Modular Crawler)

LFET Crawler
UT Crawler
Night Crawler

The Viper Crawler System

  • Strong permanent magnetic wheels hold the system to the magnetic surface even through several layers of paint
  • Long lasting, high torque planetary gear mechanism for travel over welds and patch plates
  • Inspect tanks, piping, pressure vessels, duct work, etc.
  • Optional encoder for distance processing
  • Zero turn-radius for fast and accurate maneuverability
  • Offset wheel design allows maximum surface contact at all times
  • Operates at variable speeds through a handheld controller
