Non-Destructive Testing (NDT)

Non-Destructive Testing (NDT) refers to tests that are carried out on a component to determine their physical condition and check for presence of cracks or defects in the material without damaging its integrity.

Here are the key NDT services that we provide:

• In-situ Surface Metallographic Examination: This is also known as SUMP. To replicate and study microstructural condition, micro-cracks and creep damage in materials.
• In-situ Hardness Test: To measure the hardness of base material, weld region and heat-affected zone which may have implications on the metallurgical condition of the material and weld joints.
• Internal Bore Oxide Measurement: To determine the internal scale of the super-heater and the re-heater tubes for an estimation of the effective tube metal temperature and remaining life.
• Positive Material Identification (PMI): To determine chemical composition of material to check for compliance with material specifications.
• Infrared Thermography: To determine operating temperature of components and to check for presence of hot or cold spots which may affect the service life of a facility.
• Remote Visual Inspection (RVI): To facilitate inspection at locations which are too deep in or not directly accessible to the human eye which may involve his may involve robotic or fiberscopic inspection.
• IRIS and Eddy Current Inspection: To check on physical condition, wastage and defects in tubes or pipes. We have developed a customized probes that can check on the physical condition and defects in tubes around tight boiler bends.
