| Abstract: | Internal corrosion in oil and gas pipelines is the common form of damaging of the pipeline.Daub corrosion inhibitor can delay the pipeline corrosion.The industry technology of pipeline corrosion inhibitor pre-film job using the pigging was summarized and introduced.The calculation method required before pigging prefilming was provided.Field practical application shows that using pig for pipeline corrosion inhibitor pre-film has advantages of good film-forming, simple operation and repair in service, providing a convenient method for pipeline corrosion prevention. |
