The anticorrosive work for pipeline is a long-term basic work. It is significant for us to lengthen pipeline working life and enhance the operation reliability. In this article, the corrosive status in quo and reasons for pipeline in Panjin oilfield were narrated. In accordance with the corrosive characters, the new anticorrosive coating that epoxy heavy anticorrosive over-rust primer/IPN topcoat was opened up. In the lab, the anticorrosive coating by analyzed with electrochemical impedance spectroscopy (EIS), and scanning electron microscopy (SEM). The corrosion behavior of the new anticorrosive coating was compared with that of the traditional asphalt paint. The conclusion is that the epoxy heavy anticorrosive over-rust primer/IPN topcoat is superior to asphalt paint in anticorrosive properties.
