Rapid Ultrasonic Gridding, or RUG, inspections are robot-enabled ultrasonic inspections that produce thickness grid maps to identify areas where corrosion and other damage mechanisms have caused wall-thinning. Gecko’s fastest robotic service is designed to cover an entire asset in as little as one shift. RUG is a replacement for traditional hand-held gridding with variable grid sizes from 12” x 12” to ¼” x ¼” (0.3 x 0.3m to 6 x 6mm). It is suitable for any ferritic surface with temperatures up to 275° F (135° C). Typical RUG inspections collect 1,000x more data at 10x faster inspection times.

Data_Icon_Light_Reef

Data

Each sensor takes 150-250 readings per foot, which enables you to catch small but potentially dangerous areas or concerns.

Speed_Icon_Light_Reef

Speed

The TOKA series can travel up to 60 ft/minute (18 m/minute), greatly shortening inspection time.

Saftey_Reef

Safety

Robotic tools take away the need for humans to enter confined spaces or work at dangerous elevations.

Versatility_Icon_Light_Reef

Versatility

The TOKA series models can inspect a wide range of assets: boilers, tanks, piping, pressure vessels, and more.

Coverage_Reef

Coverage

Variable grid sizes from 12"x12" to .25"x.25" (0.3 x 0.3m to 6 x 6mm).

Visual Inspection

Along with thickness readings, our robots provide complete visual coverage of the asset with thousands of HD images.
