Özet:

 

Cathodic protection is one of the most widely used  applications for protecting underground and submarine metallic  structures from corrosion.  This method is based on providing the  electrons, which metallic structures lose as a result of electrolytic  reaction, by the cathodic protection system.  However, from time to  time, it may be possible that there is some unwanted interference  input into the metallic structure in such applications.  This study is  aimed at ascertaining the existence, arising frequency, and magnitude  of an interference called the telluric effect that is going in and out  of the natural gas pipeline between Düzce and Karadeniz Ereğli in  Turkey, which is 60 km in length and has a 40.64 cm diameter, and is  well coated with polyethylene.  In this study, the pipe/ground  potential values, electrical currents coming from the anode bed, and  soil resistivity values were measured at different times and regions  along the pipeline.  In conclusion, it was found that these changes  did not arise at a certain period or at any point between the Düzce  PIG and Ereğli RMS station, although it did occur strongly around the  Akal Take-Off.
