Tube Corrosion – HRSG Internal Access Tool (IAT)

Tube Corrosion – HRSG Internal Access Tool (IAT)

TesTex developed an Internal Access Tool for inspections of HRSG tubes upon removal of the end cap. The crawler is placed inside the header. A probe is mechanically inserted into each tube to detect tube corrosion and capture video of the inside surface of the tube. A modest amount of scale buildup inside of the tube is acceptable.
