Study On Stray-current To Buried Metals Pipeline To Decay And Prevention Technique

Buried metals pipelin to around exist a great deal of EHV transmisson lines,substation and earth-termination system of a ground of device etc.In the oil-field currently,will release toward the earth in the movement the process because of these facilitieses in great quantities stray-current.Design or rule back track outside flow of the electric current call Stray-current.once Stray-current the inflow buried metals pipelin,again from buried metals pipelin run off,at the run off part of the pipelin current occurrence vehemence of corrosion.Stray-current corrosion BE:Decay vehemence,decay usually concentrated at the blemish part of antisepsis layer,make the pipelin take place some form pit eclipse in the in a short time,even result in oil,annoy,water of leakiness,the safe movement of serious threat pipelin.This text passes the spot inquisition and test,make sure different position EHV transmisson lines to spread the influence regulation of the electric current corrosion towards around buried metals pipelin of miscellaneously,and at miscellaneous spread the foundation of the inquisition evaluation of the electric current corrosion up,to miscellaneous spread the row which puts forward homologously handing over direct current corrosion of the tube segment of severity of the electric current influence to flowprevention measure.
