Ultrasonic thickness testing is another common FAC detection method. Technicians gather data at regular intervals along the equipment using a grid system. Our experts can use the data to trend corrosion rates and determine where the wall thickness falls below minimum requirements. Phased array corrosion monitoring can also effectively locate FAC. Phased array can be used to scan large areas of piping or other equipment. This method uses multiple elements within an Ultrasonic System along with semi-automated or automated scanners to gather large amounts of data more efficiently. The result is a detailed map of the area outlining thickness measurements in a color-coded image.
