Industrial inspections are unavoidable and may be difficult to perform. The bulk of industrial inspections are non-destructive in nature such as Eddy Current and Magnetic Testing or Ultrasonic Testing and Radiographic Testing besides Visual Testing. Turbine inspection is common in industries such as Power Generation, Nuclear and Aerospace. This is a very important inspection in these industries that depend on turbines. Turbine inspection could be conducted by one or more methods such as with the help of bore scopes that could be used to locate cracks or imperfections in blades. This is a tedious process since turbine blades are not accessible unless you strip them from the turbine. More often, this inspection is carried out in situ.
Another method of inspecting turbines is a modified visual method that involves the use of a special dye to highlight the location of cracks and other imperfections in blades. The kit consists of a cleaner for surface preparation, a penetrant for highlighting the crack and a developer to increase the resolution. Bore Sonics consisting of ultrasonic transducers is also used for locating flaws inside the rotor forging. Another difficult task is the carrying out of pipeline inspection.
The relative inaccessibility in cases and the interminably long pipelines make pipeline inspection a difficult task. Generally the Magnetic Flux Leakage In Line Inspection (MFL-ILI) tool is used to carry out this inspection. A strong magnetic field is created around the pipeline through which the tool travels and both cleans and detects the flaws in the process.
