How UT Pigging Works • Horizontally placed ultrasonic transducer sends sound waves horizontally. • 45 ° rotating mirror directs the sound waves perpendicular towards the pipe wall. • Signal reflects back to the transducer the same way it came. • Difference in time between sent and received signal measured and recorded. • Measurements of up to 1,600 times per second depending on the pipe diameter.

PIPELINE DACON INSPECTION SERVICES INSPECTION PROCESS
Progressive Pigging • Soft foam pig is launched to ensure there are no obstructions in the pipeline. • Medium or hard density foam cleaning pigs are launched to clean the line and further detect for obstructions. • Gauging pig is launched into the pipeline as a final check for obstructions, dents and ovalities that may cause problems. • If gauging plate comes back in a satisfactory condition then the Intelligent Pig is launched and the pipeline data acquired. • Data is downloaded directly from the pig to the Dacon data analysis system and an immediate initial assessment can be given.
