This system will inspect the bottom of water tanks to identify any possible corrosion with a resolution of 5 Mhz transducer. Typical plate thicknesses found in tank floors vary from 6.35mm to 7.9mm nominal thicknesses. Three major pieces of information is derived from the UT signals. They are: Plate nominal thickness, Minimum thickness and Corrosion type, bottom, top or both. Epoxy coated tanks can be inspected (if there is no air between the coating and the steel) with the system. For tanks with second stainless steel layer, only the inner layer can be inspected.
This is accomplished by design an electric driven vehicle that is equipped with an ultrasound thickness (UT) measurement system, camera, lights, sonar and cleaning brush. One electric Pump will be located on the tank top that takes clean water from higher in tank and removes the sludge away from the area around Ultrasonic Transducers (UT) to improve the data quality.
The vehicle is controlled remotely from a control room. The control room that is temperature controlled and is suitable for two operators to work in must be provided by the customer.
