Original Thickness: The nominal or new wall thickness of the tube as specified by the manufacturer.

Measured Thickness: The current wall thickness of the tube, typically determined through inspection methods like eddy current or ultrasonic testing.

Material Type: Select the tube's material. While this doesn't change the calculation, it's crucial for context when evaluating the results against material-specific standards.

This tool calculates the percentage of material lost from the tube wall. The result helps in assessing the tube's integrity and determining if it meets operational safety standards or requires replacement.
