Remote visual inspection (RVI) is a type of inspection that is performed using specialized equipment, such as video cameras or borescopes, to remotely view and evaluate the condition of materials or components. RVI allows an inspector to examine the interior or exterior of a structure or device without the need for direct access, and can be performed from a safe distance or in difficult-to-reach locations.

RVI is commonly used in industries such as aerospace, oil and gas, and power generation, where it is important to inspect materials or components that are inaccessible or hazardous to examine directly. RVI can be used to detect surface defects, such as cracks, corrosion, or wear, and to evaluate the condition of coatings, linings, or welds. RVI can also be used to measure dimensions, assess the cleanliness of surfaces, or to verify that components are correctly installed or aligned.

RVI is typically performed by trained and certified personnel, using specialized equipment and techniques, and is often governed by specific standards and procedures. The results of the RVI are typically documented and used to identify and address any problems or nonconformities, and to improve the performance and reliability of the materials or components being inspected. RVI is a valuable tool for ensuring the safety and integrity of materials and components, and can also help to save time and cost compared to other inspection methods.
