Study on the Corrosion Mechanism and Coating Protection of Q235 Steel for Offshore Platform

Abstract

The harsh marine corrosive environment has gradually become the key factor causing serious corrosion problems of offshore platform equipment and impeding the development and utilization of oil and gas resources. For comprehensively studying the corrosion factors and laws of offshore platform facilities and proposing a scientific and effective corrosion control method, accelerated laboratory simulation experiments were carried out, and weight loss and electrochemical methods were used to study the corrosion laws and mechanisms of offshore facilities. On this basis, a coating system for the protection of offshore facilities was designed and evaluated. The research results could provide reference for the corrosion analysis and the anti - corrosion coating system design and performance evaluation for marine environment.
