CIPS / DCVG
Coating & Cathodic Protection Survey.

CIPS technique is an inspection system developed for detailed analysis of cathodic protection levels in underground pipelines.
This technique consists of continuous measurement of the pipeline potentials regarding the copper/copper sulfate reference anode.

The operator carries out a duct routing extending a fine caliber wire, the operator moves along the pipeline and the field computer records potential values.

DCVG technique, “Direct Current Voltage Gradient” is a system developed for detection and analysis in underground pipeline coating. The defects are localized by examining potential gradients in the soil, covering the pipelines to determine the flow direction of cathodic protection currents. Since cathodic protection acts in a current flow towards the steel points exposed in the pipeline, defects in the coating can be localized individually.
