Abstract Pipelines play a significant role in production and transportation of oil and gas. The use of film-former corrosion inhibitors is one of the most economical and reliable methods of controlling internal corrosion of oil and gas pipelines. In this paper, the general mechanisms of internal corrosion in oil and gas pipelines, formulation and chemical structure of film-forming organic corrosion inhibitors and their different types were reviewed. The mechanisms of film formation of these corrosion inhibitors are also reviewed based on electrochemical techniques. In addition, the selection process of corrosion inhibitors for pipelines is discussed.
