REMOTE VISUAL TESTING (RVT) FOR INTERNAL PRESSURE VESSEL INSPECTION

摘要

Remote visual testing (RVT) of large surface areas (>1 sq. meter) associated with vessel inspection requires a unique hardware approach compared to that of commercially-available borescopes, fiberscopes and videoborescopes. Faced with stricter OSHA regulations and the increased global competitiveness of today's market place, process facilities have looked toward a technical solution, including man-less entry into vessels, pressure vessels and tanks for their internal inspections. A unitized pan, tilt, light, color, zoom video inspection system was developed for use in confined-space, and hazardous-area locations associated with these components.
