摘要：
Buried pipelines are constructed and operate in dynamic environments that make them vulnerable to a number of influences that are hazardous to their safe operation. The main operating principle of the C-Scan System is the remote measurement of the strength of a signal applied to the pipeline. The attenuation of signal strength is determined by measuring the strength of the C-Scan signal carried by the pipeline at any given survey point and comparing it with the current measured in the pipeline at some other survey point.
