Remote visual inspection enables cost effective location and detection of scale formation, corrosion fatigue cracking, ligament cracking, and an array of other damage mechanisms caused by cyclic loading, changes to water chemistry, ineffective startup/shutdown and layup procedures. Common components inspected i nclude: tubes, headers, downcomers, drums, desuperheaters, a ttemporators, dry box, coal piping, fuel nozzles, stacks and all associated welds. Additionally, related components such as fans, air heaters, deaerators, feedwater and main steam piping can also be inspected remotely using advanced RDVI equipment.
