Dexon’s Inspection Methods 

Our engineers employ a combination of techniques for a comprehensive analysis. Below is a list of the key methods used in heat exchanger inspections: 

1. Dexon’s Heat Exchanger Inspection Methods 

1. IRIS (Internal Rotary Inspection System): Uses ultrasonic technology to measure wall thickness with high precision and detect corrosion or erosion inside tubes. 

2. RFT (Remote Field Testing): Utilizes electromagnetic fields to identify wall thinning and defects in ferromagnetic tubing. 

3. RFA (Remote Field Array): An advanced version of RFT that provides higher-resolution imaging and improved defect detection in heat exchanger tubes. 

4. NFA (Near Field Array): Designed for non-ferromagnetic tubing, it detects localized defects and wall thinning using electromagnetic fields. 

5. ECT (Eddy Current Testing): A fast and effective method for detecting surface and near-surface cracks in non-ferrous tubing. 

6. FSEC (Full Saturation Eddy Current): Optimized for inspecting ferromagnetic tubes, enhancing the detection of deep-seated defects. 

7. ECA (Eddy Current Array): Uses multiple sensors to scan larger areas quickly, providing high-resolution images of material degradation. 

8. EMAT (Electromagnetic Acoustic Transducer): Enables ultrasonic testing without liquid couplants, ideal for high-temperature and coated surfaces. 

9. TOFD (Time-of-Flight Diffraction): A highly accurate ultrasonic method for measuring crack size and depth in weld inspections. 

10. PAUT (Phased Array Ultrasonic Testing): Employs multiple ultrasonic beams to create detailed images of internal structures and potential defects. 

11. TFM (Total Focusing Method): An advanced ultrasonic imaging technique that delivers superior flaw characterization and sizing. 

Dexon’s Inspection Process 

Once our engineers determine the most suitable method for the project, the inspection follows these steps: 

1. Preparation: Tubes are cleaned and, if necessary, filled with a liquid couplant to facilitate ultrasonic testing. 

2. Tool Deployment: The inspection device is inserted into the tube bundle. 

3. Data Collection: The tool scans the tube’s internal and external surfaces, detecting any anomalies. 

4. Initial Report: Data is immediately analyzed on-site for rapid decision-making. 

5. Final Analysis: Detailed reports, including defect severity and recommended actions, are provided within two weeks.
