Most pharmaceutical and biotech companies experience some corrosion and rouging of their stainless steel surfaces. Rouge can often be found in high purity water and steam systems as well as process equipment exposed to corrosive environments. There are several factors that can contribute to rouge formation including presence of halides, oxidizing chemistries, extreme pH's, high temperatures, dissimilar metallurgy or defects, improper welding, and inadequate passivation. This presentation will be divided into two parts: Part I will cover the different types of rouge, its formation, and industry practices for derouging and passivating stainless steel, this part will also provide some laboratory generated data (including XPS and Cr/Fe) demonstrating the characteristics and performance of derouging solutions. Part II will focus on presenting case studies including recommendations and procedures at different facilities.
During the webinar we will discuss the following:
- What is stainless steel?
- Passivation definitions and industry standards
- Nature, type and causes of rouge
- Solubility of iron oxides
- Routine “maintenance” derouging
- Issues to consider for manufacturing processes
- Several Case studies
