Phased Array Corrosion Mapping Technique

Ultrasonic corrosion mapping is a intrusive inspection technique that maps material thickness using ultrasonics reflection. Variations in material thickness due to corrosion can be identified and graphically portrayed as an easy to interpret picture.Recognition from various inspection bodies and asset integrity engineers has resulted in phased array ultrasonic testing (PAUT) becoming the preferred technique for corrosion mapping.

PAUT is widely used for the in-service detection and characterization of corrosion in pipes, tanks, vessels, and other critical assets. Due to a larger footprint, PAUT probes can cover a larger surface at higher speeds leading to a significant time reduction and enhanced resolution.The Modfield’s has specialized scanners and probes to offer the efficient inspection options for detecting loss of wall thickness due to corrosion, abrasion, and erosion. Our solutions can also detect mid-wall damage, such as hydrogen-induced blistering or manufacturing-induced laminations, and easily differentiate these anomalies from loss of wall thickness.

 Phased array testing helps make corrosion inspection fast and efficient. Our solutions enable inspectors to be more productive and collect higher resolution data with fully encoded C-scan imaging.
