The losses due to copper corrosion in H2S atmospheric corrosion have attracted much focus. It’s important to improve copper corrosion resistance that the corrosion law, corrosion mechanism and characteristics were studied in H2S environment. This paper reviewed the corrosion behavior of copper, analyzed the impact of environment factors and corrosion analysis tools. Through evaluating and improving corrosion by external factors, including improving corrosive environment, using coating protection and adding corrosion inhibitors, appropriate corrosion measures were taken to extend the life of the equipment.

Copper corrosion in air containing sulfur dioxide atmosphere was described in detail, for which was one of the most primary atmospheric corrosion.In the first, effection from the synergy of pure sulfur dioxide gas and mixed gas on copper corrosion was set out, together with the introduction of certain corrosion products and formation mechanism. Besides, initial copper corrosion behaviors in variety gas concentration as well as different film thickness were summarized using electrochemical method. The research prospects were depicted in the last.

The rate of carbon steel in SO2 Atmospheric Corrosion was modeled by grey model GM (1, 1). The accuracy and rationality of prediction model have been evaluated. The result indicated that the model had a better fitting accuracy. By comparing the calculated values with a predicted atmospheric corrosion rate of carbon steel after 264h, it showed that its relative error has been just 0.5619% which had higher forecast reliability.
