Close Interval Surveys (CIS): Verifying CP Performance
Close Interval Surveys provide a detailed assessment of cathodic protection effectiveness along a pipeline. By collecting pipe-to-soil potential measurements at regular intervals, CIS helps identify under-protected areas, interference issues, and overall CP system performance.

DCVG & ACVG Surveys: Locating Coating Defects
DCVG and ACVG surveys are proven methods for identifying and prioritizing coating defects on buried pipelines. These surveys help operators pinpoint holidays, assess coating integrity, and focus repair efforts where they’re needed most.
Pipeline Current Mapper (PCM): Evaluating Coating Condition
PCM surveys use AC current attenuation to qualitatively evaluate pipeline coating condition over long distances. This method provides valuable insight into coating performance and is often used alongside CIS and voltage gradient surveys for a more complete integrity picture.

Atmospheric Corrosion Surveys: Addressing Above-Ground Risk
Atmospheric corrosion can significantly impact exposed pipelines and structures. MATCOR’s atmospheric corrosion surveys evaluate environmental conditions, identify corrosion contributors, and deliver actionable recommendations to reduce long-term risk.
The same MATCOR technology used in these surveys is trusted to help protect NASA’s Vehicle Assembly Building from atmospheric corrosion.
