Research Status and Progress of Pressure Vessel and Pipeline with Coating in Oilfield

This paper reviews the anti--corrosion coatings that are applied in oil pipelines and pressure vessels in oilfield, including organic coatings, inorganic coatings and inorganicorganic composite coatings. The composition, anti--corrosion coating performance characteristics and application of the coatings were briefly introduced. Three main anti--corrosion mechanisms including the shielding effect, corrosion inhibition feature, and electrochemical corrosion protection function of anti--corrosion coatings were investigated. The main factors affecting the quality of coatings were also discussed. Finally, the research progress of novel coatings was concerned, and the issues that should be mainly noted research and applica tion of anti--corrosion coating technology in future were proposed.
