Boiler Tube Inspection Services

NDTS India provides in-service boiler tube inspection services using a portable system designed for measurement of thickness of in-service boiler tubes and detection of the most common failure modes with none or minimum surface preparation. The system uses electro magnetic acoustic transducer (EMAT) method to perform ultrasonic non-destructive measurements and detection. During an inspection, the probe is manually scanned along the boiler tube while the system records the thickness and alarms if the tube is below a pre-programmed threshold or other defect conditions are triggered. The system saves a complete record of each tube and the whole boiler for later post-analysis and tracking. Materials inspected: in-service carbon steel boiler tubes; tube thickness from 0.150" (3.8 mm) to 0.500" (12.7 mm); minimum tube diameter 0.875" (22.2 mm); and surfaces can be oxidised, roughed or pitted (scale-free). Inspection technique: EMAT ultrasonic non-destructive test method, pitch-catch sensor configuration produces an
