The values of soil voltage gradient pipe to soil potential and stray current of buried pipeline have been measured.The measured data demosstrated that interference of stray currrent is the major reason to cause bruied steel pipeline corrosion,it provides the basis for design of mitigation of stray current or other protection means.
