Robotic Shell thickness Gauging:

An ultrasonic technique called “corrosion mapping” maps and determines variations in material thickness caused by corrosion. An automatic or semiautomatic scanner is used to scan an inspection surface utilizing different ultrasonic techniques, including as pulse echo, eddy current, and phased array, in order to perform corrosion mapping.

For the inspection of pipes, pressure vessels, storage tanks, and reactors, corrosion mapping is frequently used in the oil, gas, and nuclear industries. The advantage having position and size data for every fault that can be compared for repeat scans of the same area to track flaw growth or corrosion rates both generally and for specific pits is that corrosion mapping results have a high degree of repeatability. Measurements of ultrasound wall thickness are crucial information for assessing the tank shell thickness. For this reason, Invert Robotics has integrated cutting-edge UT equipment onto our robot crawlers and is called robotic B Scan of shell thickness. The front of the robot has a buggy with encoder wheels that allows it to perform both B scans and spot measurements without the need for humans to enter limited locations or work at heights. In order to conduct cost-effective A and B-scan imaging of above-ground ferro-magnetic structures, such as oil storage tanks, the Scorpion B-scan is a tough remote access ultrasonic crawler. Rope access or expensive scaffolding are not required.

With the use of an unique “Dry Coupled” ultrasonic wheel probe, the Scorpion remote access crawler does not require conventional couplant. This enables the crawler to move horizontally, vertically, or even upside down while remaining completely functioning. The dry linked TWP12 twin wheel probe’s thickness measurements are continuously recorded by the Scorpion B-scan system, which also incorporates encoder information.B Scan ultrasonic thickness gauging instrument or robotic scanner is approved by all the major oil and gas companies and oil Gas contractors.
