Automated Corrosion Mapping, referred to as AUT, uses powered, mechanical scanners to locate defects within a given material. This method of inspection is used to obtain repeatable corrosion maps to measure flaws, show their position and the extent of the flaw. It can be applied to pressure vessels and piping to assess blistering, Hydrogen Induced Cracking and Stress Oriented Hydrogen Induced Cracking damage. With the equipment reference below, Streamline Inspection can perform a 100% surface scan, produce a detailed map of the corrosion found and calculate the length, width, depth and orientation of the flaw.


At Streamline Inspection we are using the ProScan XT, the smallest and most powerful single-channel UT flaw detector. The ProScan is user-friendly and cost effective while performing high end performance scans. The software includes A-scan, B-Scan, C-Scan and 3d displays specifically designed for Corrosion Mapping.


Along with the ProScan XT, Streamline Inspection is using the Jireh Navic Crawler. This crawler is a modular, motorized, steerable scanner designed to carry multiple attachments. It is a remote operated scanning platform and is capable of circumferential scans from 2.75” minimum OD to flat surfaces and longitudinal scans from 12” minimum OD to flat. It has magnetic wheels using rare-earth magnets so that is can operate on vertical, horizontal and inverted surfaces.


Some advantages of Automated Corrosion Mapping:

– Scans are repeatable

– Can run smaller scan sizes for increased productivity then stitch scans for complete inspection view.

– Find minimum thickness quickly

– Scan data can be compared to track any flaw growth or corrosion rates for the entire object or any individual flaws found.

– Equipment may remain in service while performing this inspection


Applications for Automated Corrosion Mapping:

– Vessels

– Tanks

– Steel Plates

– Some piping
