Advance NDT

In TOFD, a pair of ultrasonic probes—transmitter and receiver—are placed on opposite sides of the weld. The transmitter sends an ultrasonic pulse, and the receiver picks up lateral waves traveling along the surface, back wall echoes reflected from the inner wall, and most importantly, diffracted signals from defect tips (if present). By analysing the time of flight of these diffracted waves, the precise depth and size of discontinuities can be calculated with high accuracy.

We use automated scanners and TOFD-specific instrumentation to deliver precise, high-resolution imaging for critical inspections in industries such as oil & gas, power generation, and petrochemical.

This technique utilizes flexible or rigid optical devices equipped with high-resolution cameras and lighting to inspect inside turbines, pipes, vessels, heat exchangers, engines, and other confined spaces—without dismantling equipment or requiring man-entry.

Our trained inspectors use state-of-the-art borescopes and videoscopes to deliver clear, detailed visuals that support efficient decision-making and documentation.
