The Criticality of Industrial Inspection
The productivity and cost effectiveness of any industry is dependent on the level of working efficiency that the industry enjoys. This is true for Automotive and Aerospace Industries as much as for Nuclear, Petrochemical, Power and Pharmaceutical Industries. Maintenance inspection is the only method by which higher efficiencies can be enjoyed by any industry and industrial failures and breakdowns be brought to the lowest possible level. In a running industry, non-destructive method of testing or NDT is the only viable form of maintenance inspection practiced as the majority of industries run round the clock. NDT being practiced by industries generally fall within the confines of Eddy Current Testing, Magnetic Testing, Dye Penetrant Testing, Radiographic Testing and Ultrasonic Testing. The first of the two most important areas that require to be tested relate to turbine inspection in respect of Power Generation, Nuclear and Aerospace Industries. The second most important area relates to pipeline inspection in respect of almost all industries but especially the Refining & Petrochemical, Pharmaceutical, and Nuclear and Power Generation Industries.
The NDT method often used for pipeline inspection is the Magnetic Flux leakage (Induction) or MFL. In this form of inspection, applicable for steel pipelines, a very powerful magnetic field is created in the pipeline. The missing flux lines are therefore analyzed. An advanced form of pipeline inspection adopts the Inline Inspection Tool in the MFL or the MFL-ILI. The tool travels inside the pipeline and both cleans the pipeline and detects the flaws.
Turbine inspection is again a very critical area of industrial inspection since in most cases where turbines are used, whether in the Power or the Nuclear Industry, these assume the most important role. Turbine inspection can be carried out visually or with the help of a magnifying glass in case the blades have been stripped. The borescope is a useful method of carrying out the inspection as well as it can reach areas that are otherwise inaccessible. The dye penetrant is also an effective method. It uses a cleaner as a solvent for degreasing, a penetrant for soaking into the cracks, and a developer that shows up the flaws clearly.
