A borescope inspection of gas turbines tends to be more complicated than other standard inspections conducted in the industrial and manufacturing industries. This is due to the higher temperatures that gas turbines operate at which can be as high as two-thousand degrees Fahrenheit.
These inspections are crucial however, and without them internal issues could go undiscovered leading to potential damage and failure. Borescopes are essential for this inspection process, and an inspection should never be performed without them.
A borescope enables inspectors to see into parts of the machine that would otherwise be difficult or impossible to view. This allows for an inspection without damage to the machines, and risk to operators.
The borescope itself can be both flexible or rigid, include lighting, and additional viewing lenses to allow for viewing the interior of the turbine. An operator will use this to carefully inspect the
