Corrosion is the deterioration of the metal as a result of itsreaction with the surrounding environment. The corrosion in the pipelinesthat carry petroleum products is considered as the main problem facingpetroleum products pipelines which is as a result of its reaction withenvironment that include soil, its salts and water. The corrosion resultingfrom this reaction is called external corrosion which is more dangerous, therefore it will be considered more than internal corrosion that occur betweenpipe internal surface and petroleum product compounds.The present study aimed to investigate the effect of differentenvironments and different kinds of soil through which pipeline buriedextends from Shagara (Khartoum) to Port Sudan, and it is also aimed at thedetection of the effectiveness of coating and cathodic protection system that ithas followed.Also in this study chemical analysis has been done to examine thesorts of soil surrounding the pipeline and its chemical properties. Theseproperties include soluble salts, degree of acidity, soil resistivity and relativehumidity, and have followed the pipe inspection that has been carried out byPipeline Integrity Inspection Company (PII) 2002-2003, and on the view ofstudy it can be evaluated. Through this study the obtained results show thatthe soil in Khartoum, Shendi and Atabara areas is non corrosive because ofthe low soluble salts and also its corrosion resistance is very high, and is drymost of year months, moreover it is an alkaline soil.The inspection results indicate that the corrosion is spreadingextensively in those areas because cathodic protection is poor. On the otherhand corrosion is very weak in Port-Sudan area, although the soil in this areahas a very low soil resistivity, very high insoluble salts, and high relativehumidity but cathodic protection is extensively used in this area. So the studyaccessed that most corrosion occur under the tape, that means corrosion is notas a result of coating defect surrounding the pipe which indicate thatcorrosion is not connected to the circumstance surrounding the pipe, but itmay be as a result of the poor protection due to the less number of thecathodic protection stations, or defects in the type of pipes material that is wasmade of, manufacturing process, or coating process methods. A worthy studyand searching should be carried for this phenomenon. The study alsorecommended some methods used on control and monitoring of pipelinecorrosion.
