SpletPipeline current mapping (PCM) 3. Direct examination. After the data from the indirect assessment methods are analyzed and reviewed, locations for direct examination are … SpletCPM proposed to complete a two-step testing process to identify and pinpoint coating anomalies. The first step was to use our pipeline current mapper (PCM) tool to identify segments of the pipeline with the highest probability of current loss. Then in step two, we conducted a direct current voltage gradient (DCVG) survey in that segment to ...

SpletCathodic protection is a corrosion control technique used to mitigate the corrosion of underground or submerged metallic structures. There are two types of cathodic... By: … SpletCathodic protection (CP; / k æ ˈ θ ɒ d ɪ k / ()) is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. A simple method of protection connects the metal to be protected to a more easily corroded "sacrificial metal" to act as the anode.The sacrificial metal then corrodes instead of the protected metal. seattle public tennis courts
