Caliper Pigging

Caliper Pipeline Integrity Gauges (PIGs) use mechanical arms to accurately record the geometric conditions of a pipeline as well as pipeline features by measuring changes in a pipeline’s internal diameter (I.D.). This information is critical during the pre-inspection qualification process in preparation for inline inspection runs. Caliper PIG’s are regularly used in conjunction with other forms of intelligent pigging such as Ultrasonic and Magnetic Flux Leakage (MFL) inline inspection.
