Agenda Introduction to FirstMap Corrosion Mapping Technology Description Application Scope Product Demonstration Recent Study Q&A

About Imperium Founded in 1996 Sole provider of ultrasound camera technology Patented technology Systems in petrochemical, aerospace, medical fields

Why Industry Needs A New NDT Device Lack of trained NDT personnel Lack of confidence in thickness readings, missed corrosion Need higher POD, faster device Need areas where AUT can’t reach Advances in imaging technology A picture is worth 1000 words Time and cost pressures – Need to do more with less

FirstMap Advantages Images are easier to interpret FirstMap provides an actual image of the defect including thicknesses Very fast High resolution Higher confidence than single thickness readings Not effected by beam dispersion Built in delay line No extensive training required; less trained technician Real time

Optical Architecture: Ultrasonic Architecture: Imperium’s Patented Architecture Applies optical imaging techniques to ultrasound Optical Architecture: Optical Sensor (CCD) Flash Lens Ultrasonic Architecture: Imperium’s is a sole source provider of a patented ultrasonic-based camera. The design and how the product functions are somewhat similar to a traditional cam recorder. In the picture above, a cam recorder has an optical architecture based a flash, a set of lenses, and film or more typical today an optical sensor which is based on a technology called Charged Coupled Device (“CCD”). In the world of ultrasound, the camera has an acoustical flashlight, a set of acoustical lenses, and a proprietary ultrasonic CCD or sensor that captures the sound and displays the image instantaneously.

Pipeline Corrosion Mapping

Storage Tank Bottoms Compare FirstMap’s easy to interpret readout

Microbiological Induced Corrosion Black areas indicate MIC, note the veins of MIC also

Benefits to NDT Industry Broad application base Pipelines, storage tanks, pressure vessels Find smaller amounts of corrosion faster Does not sacrifice any current data quality Provide better information to end customer Better tool to provide comparisons Use Level 2 thickness inspector to generate images, not just readings Get to areas where current tools can’t go Cover more area faster while capturing better data

Advanced Corrosion Technologies “The probability of detection is far superior to standard thickness readings. FirstMap™ is a diagnostic tool that can instantly detect subsurface corrosion down to 1 mm pits. We are now able to quickly and easily identify problem areas that could potentially lead to much bigger issues.” -Josh Fontenot, Director of Technologies, ACTT

FirstMap Demonstration

About Study Wanted to compare Imperium’s FirstMap Corrosion Imaging system to Phased Array UT (PAUT) Investigated resolution Other factors included ease of use, cost, training requirements Joint study between Imperium, Inc. (Beltsville, MD) and Advanced Corrosion Technologies & Testing (Sulphur, LA)
