• Derouging and Passivation

    A Difficult Industry Challenge

    Biotechnology manufacturing facilities house the world’s most state-of-the art stainless steel manufacturing equipment. Stainless steel corrosion, or rouge, is an industry-wide problem that, left untreated, can cause:

    • Problems with equipment cleaning and validation
    • Equipment downtime
    • Reduce equipment life
    • Product contamination

    Removing rouge and enhancing the corrosion resistance of stainless steel equipment are essential preventative maintenance requirements for any manufacturing facility.
