IRIS (Internal Rotary Inspection System) is a precise, ultrasonic NDT (Non-Destructive Testing) method using a rotating mirror probe to measure tube wall thickness and detect flaws (corrosion, pitting) from the inside, crucial for industries like oil & gas/power for inspecting heat exchangers, boilers, and pipes, ensuring asset integrity by working on various materials.

Key Uses & Applications

• Critical Equipment Inspection: Boilers, heat exchangers, air fin coolers, feedwater heaters, and process piping.
• Material Versatility : Works on ferrous (steel) and non-ferrous (copper, alloys) tubes.
• Flaw Detection : Identifies localized corrosion, pitting, and wall loss with high accuracy.
• Precision Measurement : Offers accurate remaining wall thickness measurements and defect profiling.
• Backup Technique : IOften used with or as a backup to electromagnetic testing (e.g., eddy current).

Advantages

• High accuracy for wall thickness and defect sizing.
• Works on all tube materials and types (even finned tubes).
• Provides detailed cross-sections of defects.
