| Abstract: | According to the service environment of buried pipelines,an experimental platform for alternating current(AC) interference corrosion was set up.The corrosion depth of buried steel pipeline in simulated soil solution was analyzed by the method of corrosion weight loss.Influences of stray current,soil electrical conductivity and soil pH on corrosion depth were also investigated through experiment study.The results showed that AC stray current was the main factors that affected corrosion rate.Steel pipeline's ... |
