VIDEO PROBE

The object of this nondestructive testing method is to provide visual inspection of any material or object with internal surfaces or components accessible only through small diameter tubing, ports or passages. The inspection can identify and/or locate loose or vibrating parts, surface condition abnormalities, corrosion, coating or seal deterioration and other discontinuities. Direct video viewing is achieved by use of a miniature video camera that transmits signals electronically to a processor for immediate high-resolution colour display on the operator's monitor. The operator can freeze the image for examination, record on videotape and add data and references to the image.

Typical items inspected include turbines (for loose or damaged parts), steam headers (for corrosion), heat exchanger tubes, process piping, pressure vessels, rotating equipment, and commercial and residential plumbing.

The distance from the area of interest to the probe can impact the inspection, as well as the configuration of the item to be inspected. Opaque substances cannot be inspected by this method. A highly corrosive or high temperature environment will damage the equipment.

Following the inspection, a report detailing the findings is submitted. If required, a videotape record of the inspection can be supplied along with the report.
