Iris inspection is a technique used to inspect tubes and other equipment with small internal diameters. The technique involves inserting a probe into the interior of the tube, which captures high-resolution images of its inside.

Iris inspection is valuable for detecting issues such as corrosion, pitting, cracks, and other damage within the tubes. By allowing visualization, iris inspection enables inspectors to detect problems that might not be visible during traditional visual inspections.

​

Iris inspection is a non-destructive technique, meaning the equipment does not need to be deteriorated for inspection. This is crucial in industries such as petrochemical and oil & gas, where the deterioration of equipment performance can have a significant impact on production and profits.

The iris inspection technique is also effective in identifying deposits and scaling that could affect the quality and efficiency of liquid or gas flow through the tube. Early detection of such issues can help prevent the need for complete tube replacement, reducing costs and downtime.

However, it is essential that the inspection is performed by specialized professionals to ensure it is done correctly and provides consistent and reliable results.
