AUToPipe: Automatic Ultrasonic Testing of Pipes

AUToPipe is an inspection automation system for ultrasonic NDE of line pipes. The system can be customized to various diameter ranges and lengths (6-26 inch diameter and 12 m length typical) and can be programmed to perform both full volume (API-5L) and clad bonding inspection (API-5LD).

The system is capable of defect detection thresholds better than demanded by pipeline standards such as ASTM E578. The number of ultrasonic acquisition channel electronics can be tailored to deliver inspection speeds ranging from 15cm per min to 200cm per minute of 12 inch diameter pipes with full surface coverage.

AUToPipe cartable offers a portable workstation with a small motion system to test small lengths of pipe (up to about 12 inches) from the end as an x-ray replacement scan system for pre welding inspection of beveled or finished ends.

AUToPipe produces developed surface c-scan images of the pipe under inspection and contains interactive software to locate and size indications and classify them as required by the end users acceptance standards.
