              Abstract：This paper we discussed the steel corrosion of recycle water tower in petrochemical industry which is caused by improper superficial treatment and corrosion proof materials. According to the analysis on the corrosion proof coating and the reason of steel corrosion, we adopted a polyamidematerial as a corrosion coating. It has been using for two years, and has a perfect effect.
