Abstract

Based on on-site gathering and transportation pipelines, commercially available foam pigs and cup pigs were used to treat the No. 20 steel that had been immersed in simulated oil field produced water for 72 hours. Electrochemical methods and surface morphology observation were used to study the influence of different pigging balls on anti-corrosion effect of pipelines. The results show that after pigging, internal liquid and solid deposits in the pipeline were significantly reduced, and pigging treatment helped to improve the corrosion resistance of the pipeline. Under the same interference condition, the anti-corrosion effect of cup pig was better than that of foam pig.
