Inspection Techniques & Capabilities 

Dexon deploys a combination of electromagnetic, ultrasonic, and visual inspection techniques to assess tube integrity and detect defects across a wide range of materials.

• RFT → Best for rapid corrosion screening of carbon steel pipes 
• IRIS → Best for accurate wall thickness measurement 
• ECT → Best for fast crack detection in non-ferrous tubes  
• RVI → Best for visual confirmation and general condition

Access Solutions for Difficult-to-Reach Areas 

Heat exchanger inspection is primarily performed at tube level; however, access constraints can arise in elevated or congested installations. 

Dexon supports inspection execution with: 
• Rope Access (IRATA-certified): Enables access to elevated exchangers, air coolers, and structures where scaffolding is impractical  
• Drone Inspection (UAV): Supports external condition screening and inspection planning for large or difficult-to-access units
