Maverick RVI Department Summary
Maverick RVI Department Summary
This report contains examples of the effective use of Remote Video equipment. Although videoscopes have typically been employed for emergency diagnostics of problems, the real cost benefits of this type of inspection are found during scheduled shutdowns. Using the arsenal of RVI equipment now available to determine the necessity for disassembly, cleaning, or entry of plant equipment can streamline maintenance tasks and result in time and money being directed where it is most needed.
Remote Video Inspection or Testing, also called Video Inspection, involves different sorts of probes, camera systems, scopes, robotics, and other devices to collect images from hard to access areas. Maverick Inspection uses non-contact measurement software, laser profiling, image capture devices, digital recording mediums, built-in line locators, retrieval tools, and other technologies to maximize the abilities of this equipment. We have rated explosion proof and intrinsically safe equipment, specialized tube inspection cameras, robotic pan/tilt/zoom cameras, and a wide range of custom built systems. Maverick owns enough equipment for almost all of the possible applications we come across, without the need to bring in outside equipment. This allows us to react quickly to emergency calls, and we do not have to transfer large rental costs to our clients.
Maverick Inspection pioneered Remote Visual Testing in Western Canada, and we have provided service for more than 16 years and gathered a lot of experience. We grew as the demand grew, putting together an array of unique equipment to meet our clients' unique inspection needs. We offer complete inspection services, sales, and rentals of remote visual and equipment from videoscopes to robotics to fiberscopes. Our Remote Video Inspection Department is complemented by Laser Profiling, Ground Penetrating Radar and Infrared Thermography.
You may contact us by EMAIL or phone (780) 467-1606 for more Remote Visual Testing information.
