Sootblower Erosion Inspection in India | Boiler-Tube UT

Sootblower and fly-ash erosion follow impact direction, not the easiest inspection route. Map the exposed tube faces, use remote visual evidence to target valid UT, and keep every blocked row or rejected response visible.

Treat sootblower and fly-ash erosion as directional coverage problems.
A visual indication selects and bounds follow-up; it does not establish remaining wall.
Record tube, row, face, travel direction and achieved view before accepting a location as repeatable.
